Cuvettes
Cuvettes come in different shapes, sizes and materials. Which cuvette is appropriate for your analysis depends on the measuring wavelength and the chemical properties of the sample and solvent.
We can provide you with;
- Quartz cuvettes
- Glass cuvettes
- Polystyrene (PS)
- Polymethyl methacrylate (PMMA)
- Starna Demountable Micro-Volume (DMV) Bio Cell
Quartz cuvettes can be used at wavelengths between 200 to 2500 nm. Glass cuvettes are cheaper than cuvettes made of quartz, but only give a reliable result in the visible range (380 to 780 nm). Cuvettes made of PS and PMMA are disposable cuvettes and not suitable for organic solvents and only give reliable result between 300 and 900 nm.
When your application uses very small volume, Starna offers a solution; The Starna Demountable Micro-Volume (DMV) Bio Cell.
Starna Demountable Mico-Volume (DMV) Bio Cell
Designed for laboratories that want to perform low-volume determinations of nucleic acids or proteins without investing in a special instrument for this purpose. The Starna® DMV-Bio Cell is compatible with all major UV-Visible spectrophotometers without compromising accuracy or reproducibility.
The Starna ‘Demountable Micro-Volume (DMV) Bio Cell uses advanced precision techniques and materials and a patented optical system that ensures that sufficient energy is available to measure a low volume sample accurately and reproducibly, and over a wide absorption range. This elegant solution to a classic problem has resulted in a cell that fits into all standard cell holders.
