10mm Quartz Tube-Based Fluorescence Cuvette, 4.5ml, Molded 83, Four-Way Light, Screw Cap, 1pc/ea, C104TS19
Description
The C104TS19 is a 10mm-path-length quartz tube-based fluorescence cuvette with 4 polished optical faces (Four-Way Light) and an internal volume of 4.5 ml. Exterior dimensions measure 12.5 × 12.5 × 114 mm, with an interior chamber of 10 × 10 × 97 mm. The tube-based body provides a round-to-square optical transition that couples a threaded screw-cap closure with a standard 10 mm square light path, combining the sealing convenience of a test tube with the optical precision of a cuvette. Built with Molded 83 fabrication (monolithic fused-quartz construction — no adhesive joints), the C104TS19 delivers optical transmittance of >83% across a wavelength range of 190–2500 nm.

Why Four-Way Light Transmission?
Four polished optical faces allow excitation light to enter from one side while the detector captures emission at 90° — the standard geometry for fluorescence spectroscopy. The additional polished faces also support multi-angle absorbance measurements, Raman spectroscopy, and any technique that benefits from full optical access around the sample chamber.
Why PTFE-Lined Screw Cap?
The threaded PTFE-lined screw cap provides a leak-resistant, chemically inert seal that prevents sample evaporation and contamination during extended measurements. It is ideal for volatile solvents, heated samples, or any application where an airtight closure is essential. The screw-thread design ensures repeatable sealing force and easy one-handed operation.
Why Molded 83 Fabrication?
The C104TS19 is manufactured using Molded 83 fabrication — a process that produces a monolithic, seamless quartz body with no adhesive joints. This one-piece construction eliminates the risk of solvent attack on bonded seams, making it fully compatible with concentrated acids, strong bases, and virtually all organic solvents (excluding HF). With optical transmittance exceeding 83%, Molded 83 cuvettes deliver superior baseline stability and long-term durability, making them the preferred choice for demanding analytical workflows.
• Rinse with an appropriate solvent (ethanol, dilute acid, or deionized water) before first use.
• Handle by the frosted or upper walls — avoid touching polished optical faces.
• This cuvette is withstands all common laboratory solvents, concentrated acids, and bases. Avoid HF (hydrofluoric acid).
• After use, rinse immediately and allow to air-dry inverted on lint-free tissue.
• Store in the original packaging to prevent scratches on optical surfaces.
