Spectrophotometer Cells

Karaltay manufactures many popular types of UVVIS-NIR spectrophotometer cuvettes including micro-cells. Samples to be measured for absorbance or transmission are held in cells for all common spectrophotometers. Our cells comply with international standards and are compatible with many brands of spectrophotometers. Now it has formed 16 series and 500 different kinds of cells.

1A. Karaltay Advantage

Karaltay cuvettes are 100% handcrafted and 100% individually inspected. A unique Karaltay advantage is that all quartz cells are fused and ready for ultrasonic cleaning plus heavy solvent use. We developed the melting cementation technology of integrated forming and achieved the international advanced level. We overcame the limitation of low technology content: degumming, leakage, low light measuring precision and etc..
