Lid 40mm, 14mL, 2 Windows, Long Path Length Cuvette, Round Bottom, QL2H40S, Cuvette for Spectrophotometers

Description Image Place Holder This is a 40 mm long path length UV vis cuvette with a volume of 14 mL. The internal width is 10 mm. This long optical path length cuvette is selected for macro volume samples or a low concentration chemical solution that cannot be easily concentrated. This cuvette is designed with 2 clear windows for use in absorption spectroscopy experiments, and two frosted sides for easy handling. This type of cuvette is not appropriate for use in fluorescence spectroscopy where it is necessary to have four polished windows. Cuvettes with four polished sides here. 2 Clear Windows for Spectrophotometers PTFE Lid Included with Each Cuvette Fabricated from UV-vis Fused Quartz (190 nm – 2500 nm) Long Optical Path Length of 40mm Door to Door Shipping Duty Unpaid (DDU) Worldwide Long Path Length Cuvette Part No – Inside Width 10 mm Material Quartz Transmission 80% or 83% Cap Type PTFE Lid Volume 14 ml Windows 2 Windows Inner Path 40 x 10 mm Manufacturing NRC / CRF / HTR* Outer Size 45 x 12.5 x 42.5mm Bottom Round Wavelength 190 – 2500nm Path Length 40 mm Include Lid, Cell *HTR: High-Temperature Resistant. Highest quality for advanced experiments. These types of cuvettes are melt and manufactured as one piece, with extraordinary resistance to high temperature (1200℃) and corrosive chemicals. Transmission is 83% over. Zero data reading variation is available on request (default <0.3%) for 2 or more pieces. Note: These HTR cuvettes can be used with most popular organic solvents, as well as acids and bases. They are compatible with chemicals such as acetone, butanone, DMF, and concentrated hydrochloric acid. *CRF: Chemical Resistant Fused. Bestseller! This type of cuvettes is resistant to most organic solvents, acids, and bases. However, it has a chance to be stained by some chemicals to the bonding edges. It’s a cheaper alternative to the HTR type. Note: please don’t use the CRF cuvette to store chemicals for a long time. Clean it after use. *NRC: Non-Resistant To Chemicals. This type of cuvette is assembled with glue. Note: Please note that these NRC 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. DO NOT rinse the cuvette with ethanol or similar solutions for cleaning.
