Varsal manufactures UV-VIS-NIR spectrophotometer cells and cuvettes, including micro-cells. Our unique fire-fused production technology assures long lasting, easy to clean, high performance cells. Varsal cells can be used with all commonly used spectrophotometers to measure absorbance or transmission and they comply with all international standards. Depending on the spectral range to be analyzed, Varsal spectrophotometer cells are available in optical glass, quartz and IR quartz glass. Our technical ability to produce cells that meet the demanding specifications of instrument manufacturers is only surpassed by Varsal’s customer service and on-time delivery.
Varsal Advantages
- Varsal cuvettes are 100% handcrafted and 100% individually inspected.
- All quartz cells are fire-fused to withstand ultrasonic cleaning and heavy solvent use.
- Varsal offers sets of 4 and 6 cells matched for transmittance < 3% (Type 1 cells with a 10mm path length). This offer includes all glass types G, Q and I.
- Varsal can custom build cells to your specification and inscribe cells with identification logos
