- Glass Spectrophotometer Cuvettes, For Chemical Laboratory
- Micro Cell With Frosted Walls And Lid Type 18
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.
- ICL’s cells and cuvettes meet the most exacting requirements of modern spectrophotometric procedures.
- The article examines the optical characteristics of such materials that will help you make the right choice before proceeding with absorbance measurements.
- This cuvette is designed to measure through a specific z dimension, so it must match the beam’s height.

- 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.
UV quartz cuvettes for UV light are suitable for transmission wavelengths from 190nm to 2,500nm and are also available in a range of path lengths. A Cuvette is a kind of laboratory glassware, usually a small square tube, sealed at one end, made of plastic, glass, or optical grade quartz and designed to hold samples for spectroscopic experiments. Irrespective of the material selected it must be borne in mind that cuvettes, except for transparent plastic cuvettes, are fragile and require careful handling. ICL’s cells and cuvettes meet the most exacting requirements of modern spectrophotometric procedures.
Glass Spectrophotometer Cuvettes, For Chemical Laboratory
The article examines the optical characteristics of such materials that will help you make the right choice before proceeding with absorbance measurements. Most often Polymethylmethacrylate and Polystyrene material use to make the plastic cuvettes. Disposable macro cuvettes with 4 optically clear sides for use in flourescence applications. International Crystal Laboratories has quartz & special IR, NIR, UV, & VIS cuvettes for any spectroscopy application. A strong, vibrant research and development group is the lifeblood of all industries. VWR will support you from the latest life science products to the guaranteed purity of organic building blocks...
Micro Cell With Frosted Walls And Lid Type 18
Consider how different sizes and optical materials will influence your processes and choose the appropriate type to get precise results. The cuvette must match your application to yield accurate information on concentration and purity. In order to choose one, the specific use and equipment have to be defined. For example, plastic may not be efficient for UV-range experiments, but it is a cost-effective alternative for all the visible light studies. Plastic cuvettes are often used in fast spectroscopic assays, where high speed is more 1 cm cuvette important than high accuracy. Plastic cuvettes with a usable wavelength range of 380–780nm may be disposed of after use, preventing contamination from re-use.

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.
