Screw-Cap Micro Quartz Cuvettes with Slit
Two-way, fully-sealed screw-cap micro quartz cuvettes with a precision slit window, 10 mm optical path and a choice of 1 mm / 2 mm / 3 mm slit width (350 / 700 / 1050 µL). Each cell is one-piece fused from Japanese JGS1 fused silica with an M10 thread and a PTFE cap — acid, alkali and organic-solvent resistant, >83% transmittance, 200–2,500 nm.
Scuvette screw-cap micro cuvettes with slit are built for small-volume UV/visible work where a narrow measurement window matters. The slit is polished into the quartz body and the cell is fully sealed with an M10 thread and PTFE (four-fluorine) cap, so it resists acids, alkalis and organic solvents and prevents sample evaporation during long runs. The two clear windows keep the 10 mm light path clean and stress-free.
Pick the 1 mm slit (350 µL) for the tightest beam, the 2 mm slit (700 µL) as the general-purpose option, or the 3 mm slit (1,050 µL) when you need more sample. Every cell ships with a solid cap (silicone gasket) by default; solid caps with PTFE gasket and syringe caps (silicone gasket) are available separately at $12.00 each. Browse the three slit widths below or request a custom screw-cap cuvette.
