Description

Types of Cuvette Materials

Previously, reusable quartz cuvettes were necessary for measurements in the ultraviolete (UV) range, because most plastics and optical glass materials absorb the ultraviolet light, resulting in interference. Now a few types of specialized plastic cuvettes are also transparent to UV light ranges. Optical Glass, plastic and all quartz material cuvettes are transparent to visible light ranges.

As the most prominent factor to consider when choosing a suitable cuvette is the material, we are going to compare these materials in more detail below:

- Optical Glass
- UV Quartz
- IR Quartz
- Plastic

While each of these materials has some advantages, it also has some disadvantages. Again counting on your experiment requirements, you should decide which of the materials are the best. Let’s start with optical glass material.
