JET ZEROTIP® are a pipette filter tip manufactured from a super clear high quality polypropylene. The surfaces of the tips are produced through a special process which makes the inner tip surface super hydrophobic, which significantly reduces sample loss and provides substantially higher reproducibility when working with critical media. JET ZEROTIP® are free of Nucleic Acids, Pyrogens/Endotoxins, PCR Inhibitors and trace metals which makes them ideal for biological samples that contain detergents. They are also Non-Pyrogenic and are DNase/RNase-free.

Macherey Nagel have expanded the HPLC product line to include the NUCLEODUR® PFAS, 3 µm HPLC and UHPLC columns
Polyfluoroalkyl substances (PFAS) are a group of highly stable synthetic organic compounds which are used in a wide variety of industrial and commercial applications as additives in consumer products such as fire-fighting foam, fiber coating, cookware, paper finishing and food packaging to name a few. Within mainstream media they are often referred to as "forever chemicals". These substances strongly bioaccumulate within our natural environment and have become ubiquitous throughout the world since the 1940's.
NUCLEODUR® PFAS, 3 µm HPLC columns provide a solution for analysing and detecting these substances. Macherey Nagel columns show a high batch-to-batch reproducibility which make them well suited for LC-MS/MS analyses due to low bleeding characteristics. The new columns are available in a 2 mm ID and 100 or 50 mm lengths. Each column is accompanied by documentation which certifies and identifies each column to it's respective batch for PFAS analyses in the laboratory.
NUCLEODUR® PFAS Delay, 5 µm columns provide high retention for PFAS compounds and are used to retain PFAS contaminants from the HPLC system, which could otherwise falsify the sample to be analysed. For this purpose the NUCLEODUR® PFAS Delay column is connected in flow direction between the mixing vessel and the sample injector, as seen in the flow diagram below.
Stainless steel HPLC columns for analytical or preparative applications are an ideal choice for your daily labwork.
NUCLEOSIL HPLC phases have gained wide acceptance as routine chromatographic packings for differing fields in modern chromatography. It is one of the first spherical silicas used in HPLC and is a reliable choice for routine analyses.
NUCLEODUR silica is an ideal base material for modern HPLC phases. It is the result of MACHEREY-NAGEL's pioneering research in chromatography for almost 50 years. NUCLEODUR HPLC columns with 1.8 µm particle size for increased separation efficiency are used for UHPLC applications.
Due to core-shell technology NUCLEOSHELL columns provide efficient separation results with a comparably lower back pressure to fully porous materials.

Repetitive pipettes are the first choice when it comes to efficient liquid dispensing. Positive displacement pipettes are often the correct solution for pipetting viscous media. The new HandyStep® touch from BRAND combines both features.
With the intuitive touchscreen display, you are able to conveniently swipe back and forth between functions and always have an overview of the essential information on your work steps. Operation is easy, even with protective gloves on. The days of manually changing tips are over as on the HandyStep® touch, lightly tapping the eject icon on the display is enough to eject the tip.
The HandyStep® touch repetitive pipette automatically recognises the volume of the new BRAND PD-Tips II. This saves time and reduces the risk of error. Tips from many other manufacturers can also be used, providing maximum flexibility.
Charging is easy and efficient: simply place the HandyStep® touch in the inductive charging stand and the battery automatically starts charging.
