Quartz Cuvettes

A plastic cuvette rack for holding up to 10 cuvettes during experiments.

Un paquet de 100 couvercles de cuve pour une utilisation avec plastique cuvettes VIS-NIR ou cuvettes UV-VIS.

Simplify the measurement of absorbance spectra of chemical and biochemical compounds with the Go Direct UV-VIS Spectrophotometer. This sensor connects to your device via Bluetooth® wireless technology or USB, making it easy to collect accurate measurements and generate full spectra, Beer’s law data, and kinetic traces of ultraviolet and visible-absorbing samples (such as aspirin, DNA, proteins, and NADH). Compatible with LabQuest® 2, LabQuest 3, Vernier Spectral Analysis®, and Logger Pro® 3, the Go Direct UV-VIS Spectrophotometer promotes student engagement through data visualization and analysis. To conduct emission spectra experiments, simply attach the Vernier Spectrophotometer Optical Fiber.
