All spectrophotometer cells are completely fused without the use of low melting intermediate glasses or cements. In other words, quartz is fused to quartz and glass is fused to glass. This eliminates strains due to differences in coefficients of expansion found in cells fused with intermediate low melting temperature glasses. Because of the fused construction, the window joints of ICL spectrophotometer cells are unaffected by all types of cleaning solutions.
- Made from JGS1 UV-grade fused silica, absorption onset occurs below 170 nm and there are no absorption bands situated between 170 nm and 250 nm.
- Our products support state requirements for NGSS, AP, and more.
- A cuvette is a piece of laboratory equipment that is intended to hold samples for spectroscopic analysis.
- In this measurement configuration, the opposite-side cuvette walls must be optically "clear" to let light pass unimpeded through the sample.
- Cuvette used in UV spectroscopy, you will end up creating trouble in the absorbance studies, and the obtained results won’t be accurate.
Our products complement your teaching and help your students engage with key STEM concepts. Now that you have seen the individual properties of these materials, let’ move on to their comparison and examine which one will fit best. For the region of the Republic of the Congo, see Cuvette Region.
Glass Spectrophotometer Cuvettes, For Chemical Laboratory
Cuvettes to be used in circular dichroism experiments should never be mechanically stressed, as the stress will induce birefringence in the quartz and affect the measurements made. All of our cuvettes also come with a range of lids and stoppers including PTFE lids and PTFE stoppers. The sample type and the processes you intend to complete can influence your cuvette selection.
Micro Cell With Frosted Walls And Lid Type 18
Made from JGS1 cuvette UV-grade fused silica, absorption onset occurs below 170 nm and there are no absorption bands situated between 170 nm and 250 nm. Exceptionally high transmittance across the UVB, UVA, visible spectrum, and near IR. The transmission spectra for our UV quartz cells can be seen below. When working in the IR spectra, especially for wavelengths greater than 2000 nm, we recommend IR Quartz Glass Cuvettes instead, as they offer high transmission for these wavelengths. Some cuvettes will be clear only on opposite sides, so that they pass a single beam of light through that pair of sides; often the unclear sides have ridges or are rough to allow easy handling.

Historically, reusable quartz cuvettes were required for measurements in the ultraviolet range, because glass and most plastics absorb ultraviolet light, creating interference. Today there are disposable plastic cuvettes made of specialized plastics that are transparent to ultraviolet light. Glass, plastic and quartz cuvettes are all suitable for measurements made at longer wavelengths, such as in the visible light range.
