10mm Quartz Screw Cap Cuvette Flat Bottom 4-Port (3.5mL) - Frequently Asked Questions

What is a flat bottom four-way cuvette used for?

A flat bottom four-way cuvette allows light transmission through all four optical windows while the flat base provides stable placement on the spectrophotometer cell holder. This 10mm path length cuvette is ideal for UV-Vis measurements requiring multiple wavelength readings or simultaneous sample/reference comparison.

Why choose four-way instead of two-way optical windows?

Four-way clear windows let you measure absorbance or fluorescence from any side without rotating the cuvette. For multi-beam spectrophotometers and reference-channel setups, four-way design eliminates the need to realign the cuvette between scans. See our complete screw cap cuvette catalog for comparison.

Is the PTFE solid cap resistant to common solvents?

Yes. PTFE is chemically inert to virtually all laboratory solvents including acids (except hydrofluoric acid), bases, alcohols, and most organic solvents at room temperature. The M10 threaded solid cap provides airtight sealing for volatile or oxygen-sensitive samples up to 120C operating temperature.
