Kuvetter
Avantor tilbyder kuvetter som engangs- eller som genanvendelige modeller. Kuvetter kan være lavet af plastik, glas eller kvartsglas (til UV-lys) og er designet til at indholde en prøve til spektrofotometriske undersøgelser. Engangskuvetter i plastik bruges ofte til hurtig spektroskopiske analyser, hvor hastighed er vigtigere end nøjagtighed. Glaskuvetter bruges typisk til prøver, hvor bølgelængden er i det synlige område og kvartsglas bruges mest til UV-området og NIR-området.
