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 light beam to a thin sample layer, keeping the required sample volume low while maintaining sensitivity. This 5mm slit cell is ideal for concentrated or limited samples in UV-Vis spectroscopy.

How does a 5mm slit cell change my absorbance reading?

Because absorbance follows A = εcl, a short 5mm path length reduces absorbance by several times compared with a standard 10 mm cell - letting you measure high-concentration samples without dilution while avoiding detector saturation.

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

Four polished windows allow fluorescence or multi-angle measurements, and the M10 PTFE solid cap keeps the narrow chamber airtight so volatile samples do not evaporate during long scans. See the complete micro cuvette range.
