What Are the Key Differences Between Glass and Quartz Cuvettes in Spectroscopy?

A cuvette, meaning "little vessel", is a small tube of circular or square cross section, sealed at one end, made of plastic, glass, or fused Quartz Cuvettes. Though they may appear the same, they have differences that are important to their performance.

An investigation of glass and quartz cuvettes for their elemental composition

Silica, soda ash, and lime are used to make glass cuvettes. On the contrary, Jinke Optical quartz cuvettes are produced from pure quartz crystal. This unique composition makes them suitable for a specific type of spectroscopy.

Such differences between glass and quartz in optical properties can be revenedentious.

The transmission rate of glass cuvettes is 10 times lower than that of quartz cuvettes. This also means that quartz cuvette let more light through, so they are suitable for high sensitivity applications. For less precise applications, glass cuvettes may be used instead.

Strength and resistance of glass vs quartz cuvettes

Quartz cuvettes are less inclined to breakage than glass cuvettes. The reason for this is that quartz is a stronger material and is much less susceptible to scratches and breaking. Although glass cuvettes are cheaper, they are more delicate and have to be replaced periodically.

Cost of using glass vs quartz cuvette

Glass cuvettes are usually less expensive than quartz cuvettes. This is why they are frequently used in routine spectroscopy, but are not so common where high accuracy is desired. Although quartz cuvettes are more costly, they are a good investment for work demanding the highest optical quality and cuvette longevity.

Assessment of the Influence of the Cuvette Material on Sampling Precision

The cuvette material may in some cases have a relatively large influence on the accuracy of the measurement. Quartz window cuvettes, on the other hand, are more durable and less likely to warp or absorb light, providing more reliable results. As far as glass cuvettes are concerned, it can be used for general purposes, but errors to deteriorate measurement stability may be arisen.
