Qvarz stocks 227 quartz spectrophotometer cuvettes for UV-Vis spectroscopy across the 190–3500 nm range. Choose by pathlength (1, 2, 5, 10, 20, 50, 100 mm), volume (sub-micro to macro), or closure type (open top, stoppered, screw cap). Standard rectangular fused-silica cells deliver flat baselines, low autofluorescence, and chemical resistance to most acids, bases, and organic solvents. Need a non-stock geometry? Custom fabrication ships in 2–3 weeks worldwide.
