The semi-micro UV-Cuvette UV-transparent disposable Cuvette is a popular 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. The Cuvette has recessed windows to help protect against scratching and fit most commercial spectrophotometers and photometers. It is 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. Size: Semi-Micro. 500/Pack. BrandTech #: 759165.
