Available in macro, semi-micro and ultra-micro sizes, BRAND UV-Cuvette UV-transparent cuvettes are a popular disposable alternative to quartz cuvettes in DNA, RNA, and protein analyses (customer testimonial) as well as many other applications between 220nm and 900nm.
UV-Cuvettes eliminate the tedious and time-wasting cuvette washing, and the risk of sample carry-over associated with reusable quartz cuvettes. Process QC applications avoid the need for qualified SOP's for cuvette cleaning.
The proprietary plastic material offers chemical compatibility superior to that of conventional plastic cuvettes of acrylic or polystyrene, and may be used with most polar organic solvents.
Cuvettes have recessed windows to help protect against scratching and fit most commercial spectrophotometers and photometers. They are grouped by mold cavity number to maximize consistency between cuvettes and reduce variation in extinction coefficient.
Use the semi-micro size UV-Cuvettes for sample volumes between 1.5mL and 3.0mL, and the macro UV-Cuvettes for samples larger than 2.5mL. Ultra-micro sized UV-Cuvettes may be used with sample volumes as small as 70µL. Ultra-micro UV-Cuvettes are available with either 8.5mm and 15mm window heights to match the two standard beam heights of most spectrophotometers.
Ultra-micro UV-Cuvettes are now available individually-wrapped, DNA-, DNase- and RNase-free, for use with critical samples.
Choose macro cuvettes for large volume samples, or for applications where chemical resistance is primary.
