Standard disposable macro and semi-micro cuvettes are ideal for kinetic measurements and are supplied in a clearly arranged and resealable packaging. These cuvettes are delivered grouped by mold cavity number to ensure lowest variation of extinction coefficient. - Clear, clean optical path with indication of optical path orientation. - Manufactured under controlled room conditions and fully automatic packaging. Cuvettes of PS: Typical range of application: 340 to 900 nm. Standard deviation at 360 nm £ ± 0.005 extinction units. Cuvettes of PMMA: Typical range of application: 300 to 900 nm. Standard deviation at 320 nm £ ± 0.004 extinction units.
