Ultra-short path quartz screw cap cells (0.1–5 mm) fully sealed with M6 / M7 / M10 PTFE threads. Built for anaerobic, volatile-sample and high-concentration measurements where open-top cells would evaporate or leak. Two-way clear windows, Japanese imported JGS1 fused silica.
Highly concentrated samples saturate standard 10 mm cells. Scuvette's short path screw cap cuvettes combine an ultra-thin 0.1–5 mm optical path with a fully sealed M6 / M7 / M10 PTFE screw thread — so you can measure strong absorbers without dilution and without evaporation. All are JGS1 fused silica for >83% transmittance.
These sealed short path cells suit anaerobic photochemistry, volatile solvents and long-duration kinetics. Need an open-top version for easy pipetting? See our short path-length cells (0.1–5 mm, open-top or PTFE lid). Compare path lengths in our path length guide.
