Background PFAS (Perfluoronated Alkyl Substances) from an LC instrument and mobile phase can interfere with the detection of PFAS in samples. The introduction of a delay column, which is plumbed before the autosampler in the LC system, will delay background PFAS to improve accuracy of PFAS measurement by LC-MS.​

This microplate centrifuge can accomodate a wide range of PCR and deepwell plates which makes it extremely versatile. Because of the limited space in laboratories, it is designed with a compact footprint to occupy less space. It also has an imbalance detection feature with auto-cut off safety, to ensure smooth functioning.

Supplier: VWR Collection

This centrifuge has been designed to provide the best results under varying loads. Having done the research, one should not compromise on quality, precision or design; with 15000 rpm spin and programmable microprocessor control, this centrifuge gives superior precision and detects even a minor imbalance.

X-Gal is a chromogenic substrate for ß-Galactosidase that forms an intense blue precipitate. Used in conjunction with IPTG in a colorimetric assay, X-Gal allows differentiation of recombinants from non recombinants in cloning experiments with vectors containing the lacZ gene. It is also used in microbiology to detect microorganisms which have ß-Galactosidase activity.

Ethidium bromide solution is a fluorescent stain for visualising nucleic acids in solution or in electrophoresis gels. The solution is provided at a concentration of 0,625 mg/ml. A final working concentration of 0,5 g/ml is easily obtained by adding one drop of solution to 50 ml of molten agarose, running buffer or staining buffer. Ethidium bromide solution in dropper bottles may be stored at room temperature for up to one year.

Dip slides for microbiological monitoring of surfaces and in liquids. Each slide has media on both sides, with a choice of the same medium, or two different media on the two sides of the slide. This allows sampling of two surfaces with every slide. Testing with dip slides is a safe, reliable, economical and fast indicator of the presence of microorganisms. Dip slides, with a push cap, have a larger contact area.
