Screw-cap quartz cuvettes for oxygen-sensitive samples, evaporation control, anaerobic measurements, and long fluorescence acquisitions. PTFE liner, septum, and cap material selection.

Demountable / detachable quartz cuvettes for viscous samples, kinetics, paste analysis. Plus how to build your own mid-IR demountable cell with MQ CaF₂ and sapphire windows.

Pick cylindrical reflectance cuvettes for powders, slurries, films and opaque solids. Outer diameter compatibility with Cary, Lambda, Shimadzu, JASCO integrating spheres.

Pick the right quartz IR cuvette for NIR spectroscopy (190–2500 nm). Path length for water bands, fabrication choice, and when to leave quartz for mid-IR.

Pick the right micro cuvette for samples from 5 µL to 1.7 mL. Path length, aperture geometry, Z-dimension, pipetting accuracy — with the decision matrix.

Choose the right fluorescence cuvette: 4-sided polish, autofluorescence, micro-volume options, quartz vs glass — practical 90° detection geometry diagrams from MachinedQuartz.
