LAB4US Professional Quartz Cuvettes High quality fluorescence UV quartz cuvettes Made by premium quartz materialLight path length ranges from 1-10 mm Capacity ranges from 0.2 - 3.5 mlCan be polished and frosted on two sides or polished on four sides Boundary dimension is 12.5 × 12.5 × 45 mm (0.49× 0.49 × 1.8 inch)Wavelength length 190 nm-2500 nm Ideal for all UV-Vis spectrometers Accurate results for optical processing, UV-Vis-NIR absorbance and transmission. The unpolished two sides prevent slips from holding the cuvette during experiments. The efficient and high light transmission design allows light to easily travel and pass through the clear sides of the quartz cuvette. Measurement shows >83% light transmission from UV to near IR. It features a transparent and clear material surface for reliable results. If polished four sides, it can be used for fluorescent spectrometer. Durable and Consistent Each piece from the set is made of outstanding quality quartz glass for sustainable and durable built. Each piece is made with precise and uniform luster without leakage, bubbles, scratches and holes. The cuvettes are acid and alkali resistant with high temperature tolerance up to 600 degree Celsius. Standard Size fits most of spectrometers available Expected High Quality LAB4US Cuvettes for Spectrophotometer from UV to NIR Expect high light transmission and clear visibility from the quartz cuvettes. It features a transparent and clear material surface for the best function. The excellent quartz materials and cuvette design allow light beam to pass through one side of the cuvette and exit through another side without obstructions from UV to Near IR. We also offer cost-effective cuvette made of glass material. Please visit our store to explore more!
