BRAND UV-Cuvette Disposable Spectrophotometer/Photometer Cuvettes, BrandTech


These disposable UV-transparent cuvettes fit most commercial 10mm-pathlength spectrophotometers and photometers. Cuvettes are manufactured from a proprietary plastic that is transparent from 220–900nm, replacing quartz cuvettes for DNA, RNA, protein purity and quantification, and other UV/visible applications, while eliminating scratching, washing and sample cross-contamination. Cuvettes also offer superior chemical compatibility for polar organic solvents, acids, and bases, including acetone, butanone, DMF, and concentrated hydrochloric acid. Cuvettes are mold-cavity matched for the lowest variation in extinction coefficient.

Ultra-micro cuvettes are available in two z-dimensions (8.5mm and 15mm) to match the beam height of most commercial spectrophotometers. A 70µL minimum fill volume conserves sample. Round caps are available for ultra-micro cuvettes to provide a plug seal for short-term sample storage. Individually wrapped BIO-CERT* ultra-micro cuvettes are DNA-, DNase-, and RNase-free, providing a purity assurance not available with quartz cuvettes.

The polypropylene cuvette rack features 16 numbered positions and can be autoclaved to 121°C (250°F).
