Ultra-micro UV cuvettes

These cells have round openings and accommodate round caps. They feature a minimal volume (70 ul) required to fill and they come in two "z" dimensions (8.5 and 15 mm). Snug fitting round caps are available (blue is standard but you can order in several different colors as well)

Transmission properties of disposable cuvettes.  Generally, UV grade cuvettes are good from about 220nm up to 980nm.  Part of this performance is the proprietary polymer used, part is the thinner windows.  Polystyrene and PMMA are not as transmissive in the UV.  None of these polymers are good for NIR measurements.
