Automatic Microscale Continuously Closed Cup Flash Point Tester
Under specified test conditions, when a sample is heated to the temperature called flash point, the sample vapor and air mixture are ignited instantly. Flash Point is one of the indicators for the evaluation of a materials' combustion tendency. If the flash point Is low, the combustion risk would be high. As for transport and safety regulation, flash point is used for the classification of "flammable liquids". Also, flash point is used for quality control index or determining the existence of highly volatile or flammable substances in relatively nonvolatile or nonflammable matter, e.g. lubricant mixed with a small amount of diesel or gasoline.
The Koehler K24880 Microscale Continuously Closed Cup Flash Point Tester works in the following manner. The temperature of the analyzer is adjusted to at least 18 °C below the expected flash point. The sample is injected into the sample cup. The operator must ensure that the sample and sample cup temperature are both at least 18 °C below the expected flash point (the sample and sample cup may be cooled if necessary). Then the sample cup is raised towards the oven forming a closed test chamber, which is not sealed.
After every ignition, the proper volume of air goes into the test chamber to supply the next ignition with oxygen to burn. The pressure in the unsealed closed test chamber should be ambient atmospheric pressure, except during the short period of air introduction and the time when the flash point is achieved. The pressure increase comes after discharge of air, so each time after the air discharges, the chambers pressure is higher than ambient atmospheric pressure. When the pressure increase exceeds the specified limit, this is recorded as the flash point temperature (which has not been corrected).

The F-AP Fast Alkaline Phosphatase Test (F-AP) is the fastest phosphatase method available to verify the effectiveness of pasteurization. This simple one step procedure requires no reagent preparation and delivers results in just 45 seconds.
Alkaline Phosphatase is a natural enzyme present in milk that is destroyed by conventional pasteurization. This makes Alkaline Phosphatase an excellent marker to verify the destruction of pathogenic microorganisms in HTST pasteurized dairy products.
With detection at levels as low as 20 mU/L, well below established US and EU regulatory thresholds of 350 mU/L, F-AP provides an early warning indicator of improper pasteurization. F-AP is approved for use by US National Conference of Interstate Milk Shipments (NCIMS), and New Zealand Ministry of Agriculture and Forestry (MAF). All Australian states have also approved the method being used in accordance with manufacturer’s instructions to undertake phosphatase testing to assess the effectiveness of pasteurization for liquid milk products.
Benefits of F-AP Test Include:

K88539 Automatic Air Release Value Analyser
Rowe Scientific Pty Ltd would like to announce the latest product from Koehler, the K88539 Automatic Air Release Value Analyser. This innovative instrument is commonly used to determine the ability of a turbine, hydraulic or lubricating oil to separate entrained air. This is a key performance characteristic in applications where agitation causes a dispersion of air bubbles in the oil.
In order to discern air release properties, the sample is heated to a specified test temperature and blown with compressed air. After the air flow is ceased, the time required for the air entrained in the oil to reduce in volume to 0.2% gives the air bubble separation duration.
Includes an integrated touch screen control panel, which guides the user from start to finish of the test operation, and provides density calculations and timing operations for measuring the air release value of the test sample.
The test unit conforms to the American Society for Testing Materials (ASTM) D3427, IP313 and related specifications. Included is an integrated circulating bath and balance, an air bath for the sinker, an automatic lift system that moves the test vessel from air source to balance sinker, and also automatically measures the time for air release for maximum convenience and reliability.
Other state-of-the-art features include an integrated circulation bath with water level indicator, integrated balance, air tube security clamp mechanism and automatic jacketed test vessel draining.
Safety features include compressed air heater overtemperature and overpressure protection circuitry.
A drying oven is available as a supplemental accessory for warming test oil to temperatures of up to 100°C
Temperature range: Ambient to 75°C
Sample Temperature Stability: ±0.1 °C
Air Temperature Stability: ±0.2 °C
Density: ±0.001 g/mL

Vacuum filtration setup with a 6 place manifold, filter holders, receivers, funnels, flasks, tubing, vacuum pump and hoses.
If you work in the field of environmental management, industrial quality control or life science, it is imperative that you have the support of a knowledgeable representative who can supply your laboratory with the correct products to accomplish your filtration goals.
With samples requiring filtration, the traditional procedure sees the liquid poured onto a filter paper in a funnel, with the particulate/solid suspended being retained, and liquid slowly collecting in a receiver.
Laboratory filtration with the aid of a vacuum pressure gradient, is a fast and efficient way to filter and obtain your sample. As vacuum is used to aid filtration, the resulting particulate is dryer as opposed to using a more passive, gravity fed system. The filtrate can be collected into a flask via the use of a vacuum manifold.
Rowe Scientific have a range of products to cater for varying vacuum filtration scenarios. We offer 3 or 6 place manifolds, filter holders and receivers, funnels, flasks, tubing, vacuum pumps, connectors and more. We have created 2 kits which enable an easy initial set up for most laboratory applications.
We currently have a great price deal on vacuum filtration kits. Click here to download the PDF brochure.
Contact us today to start building the right vacuum filtration setup for your laboratory.

The STEM X (Science, Technology, Engineering, Mathematics Exchange) Academy is a five-day residential professional learning program for primary and secondary teachers (total of 70) of science developed in partnership between Questacon – The National Science and Technology Centre, CSIRO and the Australian Science Teachers Association (ASTA) to address the national need for improving teacher and student STEM skills and content knowledge.
The program is doing something no other program does. Rather than just providing teachers with a package of resources to use in the classroom, it is helping them to acquire the skills and confidence to design, develop and implement their own teaching resources.
STEM X Academy does this by partnering teachers with skilled educators from Questacon and CSIRO and expert researchers to collaborate on projects across the five days. This fosters the building of relationships between teachers, schools and the STEM Industry.
The vision for STEM X Academy teachers is to be inspired by research, foster innovation in the classroom, act as a catalyst for change and remain connected creating a national community of practice. Strong evidence exists to suggest that all these objectives are being fulfilled.

Mr Thomas Sanfead
Our congratulations to Mr Thomas Sanfead, the 2017 winner of the ECU Rowe Scientific Prize in Chemistry.
In Thomas’s words,
“I enjoy how logical chemistry is. How the structure and shape of compounds influence their properties, and how this affects the way different chemicals interact with each other.
The various chemicals throughout the human body and how they allow us to function is fascinating.
Different chemicals, such as medicines, and how they interact with the human body, altering it to either hinder or help us is exciting.
Overall I think the role which chemistry has in the natural world is wondrous.”
Well done Thomas.

Mr Andre Wang
Congratulation to Andre Wang and Samuel Alsop who were the recipients of the 2017/18 UWA Vacation Awards in Chemistry and Biochemistry.
Mr Andre Wang
In Andre’s words on the description of his project,
"Mitochrondria are one of the most viral organelles in eukaryotic organisms such as humans and plants.
Originating from an endosymbiotic event and the subsequent loss of genes to the nucleus, thousands of mitochondrial proteins are thus required to be imported from the cytosol (Dudek et al., 2013).
These proteins have highly specialised mechanisms and utilise several receptors and transporters located in the mitochrondrial membranes. Recent studies suggest that several of these transporters are key regulators in controlling the rate of transport and thus mitochondrial function (Wang et al., 2013).
The Murcha lab within the School of Molecular Sciences have generated a range of Arabidopsis thaliana transgenic lines that overexpress certain key protein transporters such as Tim17, Tim22 and Tim23 from 2-10 fold. The functionality of this overexpression will be tested.
By isolating mitochondria from these lines, protein uptake ability can be assessed and quantifiably measured. Furthermore, a range of substrates can be investigated to identify the consequences of manipulating these transporters on the various known protein import pathways.
This project aims to therefore identify key regulators of protein uptake ability in plant mitochondria. This will elucidate targets that can be used to regulate mitochondrial biogenesis and activity resulting in plants with bigger biomass, faster growth and resistance to a range of environmental stresses.”
Mr Samuel Alsop
Samuel describes his project as follows,
“The project will involve investigating a biosynthetic gene cluster in the wheat pathogen Parastagononspora nodorum, using a variety of biochemical techniques. P. nodorum is the fungus responsible for Septoria nodorum blotch, and it is believed that it produces a number of secondary metabolites which contribute to its virulence.
As with other fungi, many of the biosynthetic gene clusters that produce these secondary metabolites are transcriptionally silent under normal growth conditions.
The aim of the project is to heterologously express genes in a biosynthetic gene cluster to produce intermediates and products of a biosynthetic pathway that has been shown to be expressed exclusively during infection of the host plant.
This will allow for the identification of the compounds using LC-MS and NMR spectroscopy. This will hopefully improve our understanding of the role that the secondary metabolite produced by this pathway may play in virulence, as well as providing insight into how it is synthesised by the fungus.
This project will be a continuation of work on this gene cluster conducted in a research project for BIO3003/BIO3005 throughout semester 2.”

Mr Stephen Delwig
Congratulations to the following two winners of the Rowe Scientific scholarship, covering the years 2017 and 2018, from the staff of Rowe Scientific Pty Ltd.
Mr Stephen Delwig
In Stephen’s own words;
“I completed both primary and secondary education in the Victorian western districts town of Camperdown. Neither of my parents were able to work during this time; my father is disabled and my mother cares for him.
After completing my final year of VCE, I acquired financial support in the form of a Dafydd Lewis Scholarship and moved to Ballarat to pursue my tertiary studies. I initially pursued a Bachelor of Mechanical Engineering at the University of Ballarat (which has since changed names to Federation University) but after two years, I decided that engineering was not my desired profession and changed courses to study a Bachelor of Science at Federation University.
I have now completed my Bachelor of Science degree (biochemistry major, microbiology minor). I have now moved to Geelong to pursue a chemistry Honours degree at Deakin University (Geelong Waurn Ponds campus).
Ms Catherine Fraser
In Catherine’s own words;
“I have recently completed a Bachelor of Science with Distinction from Deakin University. I will be undertaking an Honours year in 2018, and following this I intend on completing a PhD.
I have learnt a great deal about myself in my three years of undergraduate study. I have also developed professional skills that are applicable to any career path, and most significantly I found where my passion lay; chemistry.
Having a passion for my field has enabled my skill development. Naturally, my discipline specific skills have developed greatly, most notably, I believe, are the skills I have acquired and improved in teamwork, self-management, and critical thinking
Pursuing a career in chemistry has pushed and challenged me to take on any opportunity to learn.

The following are the two 2017 Rowe Scientific Metallurgy scholarship winners.
Mr Brendan Jones
In Brendan’s words;
My name is Brendan Jones and I am a current student at Curtin University studying a double degree in Chemical Engineering and Extractive Metallurgy.
At the end of 2017 I will have finished my third and final amazing year at Curtin’s West Australian School of Mines (WASM) in Kalgoorlie. Extractive metallurgy is a specialist field that deals with the extraction of metals and mineral products from their ores through the application of scientific principles.
Extractive metallurgists play a key role in the mining industry. Throughout the last three years at Curtin I have enjoyed every discipline which involved chemistry, and metallurgy is no different. Metallurgy incorporates all the best elements of practical chemistry from leaching to electrochemistry.
I enjoy the challenges that metallurgy provides, particularly when analysing or partially designing process flow systems and understanding the mechanisms involved.
Although learning about metallurgy is fascinating, I am very much looking forward to putting my theoretical knowledge into action with upcoming vacation work and potential employment in the mining industry in the future. I would like to extend my gratitude to Rowe Scientific for providing me with financial aid and allowing me to continue to enjoy the field of metallurgy.
Ms Tram Nguyen
In Tram’s words;
I have always been interested in chemistry since I was in high school.
The fact that you can make different kind of alloys that can be applied to real life situations just by changing the composition of the metal input is really fascinating.
As a university student, I am always supported by Curtin. The Engineering and Science department tries their best to give me chances to get my hands on real life process through the laboratories.
One of the labs really got my interest was the extraction of gold from the ore. Even though we didn’t have the chance to deal with real gold due to high cost of gold, we actually had chance to extract metal out of the sample. In my point of view, it was a fantastic process.
Starting from a mixture between two things, by using the differences in their physical and chemical properties, we are able to separate them. That’s why I really like metallurgical field.
With the support of Rowe Scientific, through the Rowe Scientific Metallurgy Scholarship, I will be able to spend more time on my study. It also helps me prove that hard work will be rewarded. Thank you for your generosity and all your supports.
30 Jan 2018
Mr Michael Van Wageningen
In Michael's own words;
I enjoy studying chemistry and plan to follow a career in that field.
I would love the opportunity to make wine in Europe and have already begun to make some connections through the University. I hope to one day start my own vineyard in Tasmania.
Being awarded this scholarship has made a big difference to my living conditions and helped to reduce stress about finances or placing additional burdens on my family.
You have changed my life in a way I never knew could happen. I am very grateful for your support and can't thank you enough.
30 Jan 2018
Ms Jessica De La Perrelle
In Jessica's own words;
I moved from the country to the University of Adelaide because of the high quality of teaching. From a young age I was passionate about 'saving the world' via sustainable technologies and still hope to work one day in research in the sustainable technology field.
I intend to graduate with honours in either physical chemistry or physics. Receiving this scholarship has had a significant positive impact and I would like to sincerely thank you for your generous support.
My intense study load means I have little time for a part time job, and rely on savings and family for financial support. The scholarship contributed to easing my anxiety and financial pressures, enabled me to purchase a new laptop, and allowed me to focus on my university studies.
This scholarship has helped me to realise a lifelong dream of researching improvements to sustainable technologies. In addition, I would like to thank you for making the scholarship available to rural, regional and remote students, as the transition to university is often so much more complex for them, and I would love to see more rural students succeeding at university.
Mr Brandt Dolic
In Brandt's own words;
I have enjoyed my studies at the University of Adelaide and hope to one day complete a PhD and work in the research area.
My favourite thing at the University is The Braggs Laboratory and the investment and facilities they have put into the research area.
This scholarship has allowed me to focus more on studies rather than be distracted with juggling the financial issues that come with moving states.
Thank you for believing in the future I want to achieve. I really enjoy synthetic chemistry and wish to continue my studies further representing this scholarship.
Thank you very much for your support.

On 23 October, 2017, the following two students, chosen at random from many winners of Rowe scientific prizes, received their awards by the STAV’s Science Talent Search.
Mr Dylan Zipsin, of Viewbank College.
Dylan won his award in the Junior (Yr 7-8) Inventions section, by inventing a Smart Lock: The “ZipVault” was constructed using complex wood working knowledge as well as the advanced use of electronic components and wiring and the development of code using high levels of logical and mathematical thinking.
It was designed to give people peace of mind, knowing that their belongings were safe and out of anyone elses reach.
The box features two extra layers of security on top of the expected 6-digit pin, with already over ten million different possible combinations, requiring a magnet to turn it on, as well as for the owner to tilt the box four times, before you are confronted with the 6-digit pin.
Once you are finished, the box locks and shuts down, using no power whatsoever
Well done Dylan.
Ms Eleeza Maqsood, of Sirius College, Eastmeadows.
Eleeza won her award in the Junior (Yr 7-8) Experimental Research section, for the following project: “Does Aromatherapy essential oils vapour inhibit the growth of Escherichia Coli?”
Abstract: Stated on the internet, it has been said that essential oil aromas can help sanitize a room of bacteria. This experiment looked at the effect of the vapour of essential oils in the presence of Escherichia Coli (E. coli) bacteria. To verify this claim, essential oils were placed in plastic wells in the centre of nutrient agar plates streaked with E. coli bacteria. The plates were left in the incubator for three days and then were moved into the fridge, and the plates were analysed. The plates were examined in sections for bacterial growth, and bacterial coverage was totalled.
The results showed that the most effective oils in descending order were tea tree, eucalyptus, grapefruit, peppermint, and lavender. Only tea tree oil and grapefruit oil were significantly effective and consistent with background research claims.
Sounds like impressive work for a Junior Eleeza. Well done, from the Rowe Scientific staff.

Ms Georgia Free, Bachelor of Science (Advanced) - Key Program: Chemistry
In Georgia's own words;
“I am a hard-working and determined individual who wants to use chemistry to better healthcare and the environment. Over the past year, I have been doing undergraduate research with potential anticancer agents, under the supervision of Janice Aldrich-Wright; focusing on synthesis and characterisation of platinum metal-ligand complexes - some of which are more cytotoxic than cisplatin!
This summer, I have received a summer scholarship with CSIRO Energy in Newcastle, and will be developing catalysts to transform carbon dioxide into usable materials, to reduce air pollution.
Receiving recognition for hard work is always a great feeling, however it is simply icing on the cake, because using chemistry to solve big problems is reward enough. Next year, I aim to study a Masters of Philosophy at Western Sydney University and this scholarship has eased a significant amount of financial burden off of my shoulders for next year. I am extremely grateful for this prestigious scholarship - and I hope to make the donors proud with my research over the next few years.”
