Manufactured from polystyrene (PS) or polymethyl methacrylate (PMMA), they provide accurate, reliable results. Choose PS for determinations above 340nm, and where cost is a concern. When performing assays above 300nm, choose PMMA. (For wavelengths below 300nm, see our UV-cuvettes). These disposable cuvettes are available in macro and semi-micro sizes to accommodate most sample volumes and are compatible with most spectrophotometers and photometers. All BRAND cuvettes are manufactured from scratch-resistant materials, and are grouped by manufacturing mold cavity number to ensure the lowest variation in extinction coefficient....

The tips are manufactured in an environmentally friendly manner using only high-purity polypropylene, free from oleamide and diHEMDA - additives which can interfere with biological All BRAND pipette tips are produced using the most advanced cleanroom techniques to ensure consistently high quality. The tips are manufactured in an environmentally friendly manner using only high-purity polypropylene, free from oleamide and diHEMDA - additives which can interfere with biological tests. Filter tips have a non-self-sealing PE filter that is free from chemical additives and allows easy uncontaminated sample recovery if the filter is wetted. Permeability is controlled by the combination of pore size and filter length, so that no aerosols can reach the pipette shaft. They are available BIO-CERT® sterile, or BRAND® ULR™ BIO-CERT® sterile in volume sizes ranging from 0.1-1µL to 50-1000µL....

BRAND's UV-transparent, disposable cuvettes replace expensive, fragile quartz cuvettes and are excellent for DNA, RNA, and protein analysis between 230-900nm. Made from a proprietary polycyclical Eliminate the need for cleaning, and the associated risk of sample carryover and cross-contamination. BRAND's UV-transparent, disposable cuvettes replace expensive, fragile quartz cuvettes and are excellent for DNA, RNA, and protein analysis between 230-900nm. Made from a proprietary polycyclical olefin, they can be used with most polar solvents, acids and alkaline solutions. In addition to the macro and semi-micro sizes, UV-cuvettes are available in ultra-micro sizes that require only 70µL of sample volume. The ultra-micro cuvettes are also available individually-wrapped and independently-certified DNA-, DNase-, RNase-free for an extra degree of sample protection. All BRAND cuvettes are manufactured from scratch-resistant materials, and are grouped by manufacturing mold cavity number to ensure the lowest variation in extinction coefficient....
