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.
- Fingerprints and droplets of water disrupt light rays during measurement, so low-lint gauze or cloth may be used to wipe clean the outer surface of a cuvette before use.
- The width determines the length of the light path through the sample, which affects the calculation of the absorbance value.
- PS and UV-cuvettes can be used in temperaures up to 70 °C.
- It is more resistant to chemical attack from the sample solution than other types designed for fluorescence measurements.
While 10 mm path lengths are the most widely used, absorption cuvettes come in path lengths ranging from 1 mm to 100 mm, as well. The most common type of cuvette is square, with external dimensions of 12.5 x 12.5 mm. This format accommodates sample volumes from the microliter range (ultra-micro cuvettes) to the milliliter range . Cuvettes are small rectangular glass or quartz containers. They are often designed so that the light beam travels a distance of 1 cm through the contents, but the path length can vary from 1 or 2 mm all the way up to 10 cm.

It has to be kept in mind as well while picking up a suitable cuvette. So when you are tight on budget, plastic will be a great alternative to go with. Fostered by enormous industrial familiarity and understanding, we are occupied in offering an extensive consignment of UV and Glass Cuvettes. Our company is among the trusted names, betrothed in offering an extensive range of Steel Ball Disposable Cuvettes. Brian Howie is a content writer and senior industrial designer. After graduation from Westminster College, he has been engaged in product design and manufacturing for 18 years.
Micro Cell With Frosted Walls And Lid Type 18
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. 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. spectrophotometer cuvette size 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.
Sheath-flow cuvette for high-sensitivity laser-induced fluorescence detection in capillary electrophoresis. These cuvettes enable you to use the minimum amount of solution, therefore you can conduct more experiments than you would normally be able to. A standard 10 mm square cuvette is actually 12.5 mm measured from the outside. Its wall thickness of 1.25 mm brings the measuring space to 10 mm, the same dimension used for most spectrometer chambers. Macro cuvettes hold a measuring volume greater than 3.5 mL. Among these types are common cuvettes ranging from 7 to 35 mL.
