1.all kinds cuvette with high quality 2.all kinds cuvette are 100% handcrafted and 100%individually inspected.

SGM  manufactures many popular types of UV­VIS-NIR spectrophotometer quartz 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.

SGM manufactures cells with different types of glass depending on the spectral range required for analysis. These materials include Optical Glass, suitable for use from 334 nm through 2300 nm and UV grade Quartz suitable for use between 179 nm and 2600 nm. The table below contains % transmission for these materials:

Material	Code	Application	% Transmission	Matching Tolerance
