- Matched pairs for less data variability
Cuvettes come in matched pairs in standard, semimicro, or micro size, and can be ordered with either a cover of PTFE resin or a stopper of PTFE resin. All cuvettes have a 10-mm pathlength. All pairs are accurately matched to give the same value for the same solution within 1% tolerance. Quartz cuvettes can be used for the entire UV spectra down to 200 nm and have a guaranteed 80% transmission at 200 nm.
