Due to the special plastic material and the excellent manufacturing process the cuvets can also be used in photometric ranges reserved for UV glass cuvets in the past. Type 1 Infrasil (IR Quartz) Cuvette with a 1mm path length and 0. A measuring cuvette ( 1 ), for the spectroscopic analysis of a gas sample in a ray path between a radiation source and a detector, preferably suitable for use in a gas-measuring device ( 19 ), has a vessel wall ( 2 ) that at least partially encloses a sample space ( 3 ) for receiving a process gas. That's one dilution. b is the path length and C is the 95% ethanol was placed in a 1 cm cuvette for measurement.
