The macro cuvettes, 4 clear sided, are suitable for fluorescence spectroscopy. The UV-transparent cuvette can be used from a wavelength of 230 nm and shows no autofluorescence. - Clear, clean optical path. - Manufactured under controlled room conditions and packaged fully automatically, without human contact. - Packed grouped by mold cavity number to ensure lowest variation of extinction coefficient.
