Quartz Micro Slit Screw Cap Cuvette - Frequently Asked Questions

What is a micro slit screw cap cuvette used for?

A micro slit cuvette has a narrow slit-shaped chamber that confines the sample to a small volume while keeping a standard optical path. This 2 mm slit cell holds just 700 µL with a 10 mm optical path — ideal for limited or precious samples in FTIR / IR spectroscopy.

How does a 2mm slit cell change my absorbance reading?

The 2 mm slit confines the sample chamber and keeps the volume at just 700 µL, while the standard 10 mm optical path keeps absorbance readings directly comparable with standard 10 mm cells — no path-length conversion is needed.

Why four-way windows with a screw cap on a slit cell?

Four polished windows allow fluorescence or multi-angle measurements, and the M12 PTFE solid cap keeps the narrow chamber airtight so volatile samples do not evaporate during long scans. See the complete micro cuvette range.
