MSE PRO Micro Cuvettes With White Walls And Stopper, 20mm Path Length, IR Quartz Glass (250nm-3500nm)

20 mm Micro IR Quartz Cuvette with Stopper, 2.1 ml, for UV-Vis-NIR Spectroscopy

A 20 mm micro IR quartz cuvette needs only 2.1 ml of sample: frosted white side walls narrow the chamber to a 3 mm inside width while light still passes through the 2 polished windows. The MSE PRO cell is made from IR quartz glass.

A 2.1 ml fill sits between micro and full-size cells, a practical middle ground for routine UV-Vis and NIR measurements when sample is limited.

The PTFE (Teflon) stopper seals the cell against spills and evaporation, which matters for volatile, precious or hazardous solutions.

IR quartz transmits from 250 nm in the UV out to 3,500 nm, the widest infrared reach in this cuvette range, so it suits NIR measurements as well as UV-Vis work such as 260/280 nm readings. For deep-UV work below 250 nm, choose ES quartz instead.

The 20 mm path length gives about 2 times the absorbance of a standard 10 mm cell for the same sample, which helps when measuring dilute or weakly absorbing solutions.

Outer dimensions are 45 x 12.5 x 22.5 mm (H x W x D). Check that your spectrophotometer's cell holder accepts this footprint before ordering.

The cell is made by temperature fusion. Other sizes and custom inside widths are available on request.
