Our cuvettes are high-quality cells designed to hold liquid samples. The synthetic quartz glass construction allows these cuvettes to be used with UV light at wavelengths as low as 190 nm, as well as with visible and infrared light up to 2.5 µm. Shengfan offers cuvettes with either two polished sides, for use in absorption spectroscopy experiments, or four polished sides, for use in fluorescence spectroscopy. The polished sides can be cleaned using standard optics cleaning procedures. Versions are also available with one of three PTFE tops: a cap to block dust and other particles, a stopper to prevent evaporation and provide a seal, or a septum screw cap to provide an airtight seal and prevent contamination until a needle is inserted.
The standard 12.5 mm square outside dimension and 10.00 mm transmitted path length through the sample make these cuvettes compatible with most spectrophotometers as well as our cage-compatible Cuvette Holder, Fiber Optic Filter and Cuvette Mount, and Holder for Integrating Spheres. We offer macro, micro, and super micro sizes (see the tables below for more information), sold in packs of two. The 100 µL cuvettes with four polished sides as well as all 3500 µL cuvettes are also available in a version with enhanced chemical resistance. All cuvettes are engraved on the outer surface with the Item # and a letter "Q" designating synthetic quartz glass construction and the typical input side.
The super micro and micro cuvettes with two polished sides are assembled with glue. Our other cuvettes are assembled by heating the quartz glass to a high temperature and applying pressure to adhere the pieces together. Of these, micro cuvettes that are polished on four sides and all standard macro cuvettes have a quartz glass powder applied to the edges before heating, while the enhanced-chemical-resistance super micro and macro cuvettes are constructed by finely polishing the quartz glass before heating.
Solvent Compatibility
All standard cuvettes should not be used with benzene, toluene, aqua regia, ethanol, corrosive solutions, or other similar substances, as they may degrade the bonds between the pieces and cause the cuvette to leak. The cuvettes with enhanced chemical resistance are compatible with corrosive solutions such as aqua regia. Contact Tech Support for instructions on cleaning the cuvettes found on this page.
For applications that require cuvettes with a enhanced chemical resistance and a shorter optical path length, we offer Enchanced Chemical Resistance Cuvettes with ≤2 mm Path Length. These cuvettes are made from either synthetic quartz glass or borosilicate glass and are available with 350 µL or 700 µL capacity.
