- Glass Spectrophotometer Cuvettes, For Chemical Laboratory
- Micro Cell With Frosted Walls And Lid Type 18
Our products support state requirements for NGSS, AP, and more. Transparent to the wavelength of light required for the purpose. Absorbance studies have become a base for examining various solutions and particles. Under these, the light gets passed through the solutions in a defined format. BrandTech also manufacuresUV CuvettesandVis (PS/ PMMA) Cuvettes. PS and UV-cuvettes can be used in temperaures up to 70 °C.
- ICL’s cells and cuvettes meet the most exacting requirements of modern spectrophotometric procedures.

- The sample cell contains a solution of the substance you are testing, usually very dilute.
- On customer’s request they can be replaced with crystal quartz, sapphire or silicon windows.
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.

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.

Cuvettes are tube-like containers used to hold samples for spectroscopic analysis that delivers accurate and reliable results. They are made from quartz, plastic, polycarbonates or glass in various sizes and are scratch-resistant. Disposable cuvettes are preferred to prevent carry over of samples. Quartz cuvettes are specifically used for measuring absorbance in the UV range and plastic cuvettes for the cuvette size visible light path range.

All cuvettes and cells are provided in matched sets and available with fitted covers, plugs, screw caps, anaerobic screw caps, graded seals and flow through ports.

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.
