General purpose cuvettes for Absorbance, transmission and other measurements in the visible wavelength range (320 to 2500nm). With various path lengths of 10, 20, 40mm for static sampling, these cuvettes will fit standard spectrophotometer cell holders, and can be used with any beam height. Some cuvette are classified as a semi-micro cells with a sample volumes of 1.4, 3.5, 7, 14 and 17.5ml these cuvettes are supplied with a square PTFE lid or PTFE stopper (CEL2014). CEL2008 cuvette is also available in matched pairs. A compact, ultra-micro cuvette is also available (CEL2022) which can be used with a beam height of 8.5mm. Ultra-micro cell with a tiny sample volume of 18µl have a ‘T’ design which enables easy connection of the optional screw-in tubing kits and enables rapid filling and flushing to minimise fill-time and carryover.
