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
Is this screw cap cuvette airtight and leak-proof?
Yes. The threaded PTFE solid cap seals against the quartz body with a precision thread, keeping the 3.5 mL sample airtight for volatile solvents and oxygen- or moisture-sensitive assays. The M10 (or M12 on the EU version) thread is fully reusable - tighten hand-tight only to protect the thread.
Two-way, four-way or five-way windows - which do I need?
Two-way cells suit standard UV-Vis absorbance measurements. Four-way and five-way cells are for fluorescence, multi-angle readings or reference-channel setups where light must enter from several sides without rotating the cell. All variants share the same 10 mm path length and 3.5 mL chamber - compare the full screw cap cuvette range.
How do I clean a quartz screw cap cuvette without scratching it?
Rinse immediately after use, flush with deionized water and a mild detergent (or 1:1 HCl for organic residues), then rinse with isopropanol and air-dry. Never use abrasive wipes, brushes or metal tools inside the optical chamber. See the cuvette care guide for the full protocol.
