These cuvettes are made from a unique material that is resistant to aggressive solvents, acids, and bases including chemicals such as acetone, butanone, DMF, and concentrated hydrochloric acid. Suitable for measurements from 230 nm to 900 nm, such as nucleic acid purity measurements. Molded for consistent performance, each cuvette is manufactured from the same mold to ensure the lowest variation in extinction coefficient. 10 mm optical pathlength. Available in macro (2.5 - 4.5 mL); semi-micro (1.5 - 3.0 mL); and ultra-micro (minimum fill volume 70 µL) sizes in both 15 mm and 8.5 mm z-dimensions to fit most major brands of spectrophotometers. Ultra-micro size cuvettes also available individually wrapped.

Ultra-micro cuvettes require only 70 µL (up to 850µL) of sample volume. The ultra-micro cuvettes certified DNA-, DNase, RNase-free for added protection. Round polyethylene caps (sold separately) provide a seal for reliable sample storage; select from four colors.
