Good product, the finish is clean and the windows are clear. Shipping took a bit longer than expected but the cuvettes themselves are worth the wait.

10mm Quartz Screw Cap Cuvette — Frequently Asked Questions
What is a screw cap cuvette used for?
A screw cap cuvette is a sealed sample cell with a threaded PTFE cap. It is ideal for anaerobic samples, volatile solvents, and any experiment where evaporation or air exposure must be prevented. This 10mm quartz screw cap cuvette is fully airtight up to M10 thread spec, suitable for UV-Vis spectrophotometry and oxygen-sensitive reactions.
How do I clean a quartz screw cap cuvette?
Rinse with deionized water, then soak in dilute laboratory detergent or isopropanol for 30 minutes. Avoid hydrofluoric acid and abrasive cleaners. Air-dry or use lint-free wipes. The PTFE cap can be unscrewed for separate cleaning. For full protocol see our cuvette cleaning guide.
Is this cuvette compatible with my UV-Vis spectrophotometer?
Yes. The 10mm path length and standard 12.5 × 12.5 mm outer dimensions fit virtually all benchtop UV-Vis spectrophotometers (Shimadzu, Agilent Cary, PerkinElmer Lambda, Thermo Evolution, Beckman DU series). For fluorescence or HPLC use, see our full screw cap cuvette catalog.
