UV-cuvette 220-900 nm / 1,5-3 ml

Square opening; window size: 4.5x23 mm; film thickness 10 mm; standard deviations: range 220-260 nm: <= ±0.007 absorption units; range 270-900 nm: <= ±0.002 absorption units. Standard semimicro cuvette for analyses from 220 nm to 900 nm wavelength! Fits virtually all common photometers for standard cuvettes. Good chemical resistance. Acids and alkalis can be used as well as the majority of polar solvents. Chemicals such as acetone, methyl ethyl ketone, DMF and even concentrated hydrochloric acids do not represent a problem. No need for cleaning as with quartz glass cuvettes and thus less risk of contamination and lower costs. Inset widows to safeguard against scratches. Sorted according to cavity number in order to avoid extinction deviations. Ideal for protein, DNA and RNA determinations. Packed on a polystyrene tray of 100 cuvettes with lid."""
