High-transparency JGS1 ultraviolet quartz cuvettes for precise optics.-Mia

JGS1 UV Quartz Cuvettes (Absorption Cells) are essential optical consumables for UV-Vis spectrophotometers and fluorescence spectrometers, specifically designed for detection in the ultraviolet range starting at 190 nm. They complete the high-purity quartz optical product line for spectroscopic analysis, offering integrated laboratory consumables together with quartz square cells, transparent quartz crucibles, and quartz reaction tubes.

Made from premium JGS1 UV fused quartz, these cuvettes feature precisely polished optical surfaces with a transmission range covering **190–2500 nm**, exhibiting no significant background absorption in the deep ultraviolet region—unlike conventional glass cuvettes, which suffer severe UV absorption below 340 nm and are unsuitable for UV measurements. The product demonstrates excellent chemical stability, resisting strong acids and most organic solvents, and shows minimal impurity leaching during high-temperature cleaning, preventing sample contamination and baseline drift.

Manufactured using a seamless fusion-sealing process without adhesives, ensuring leak-free performance; strict quality control is applied to eliminate surface defects such as streaks, pitting, scratches, and bubbles. Low batch-to-batch matching error and precise pathlength tolerance ensure consistent performance. Available in standard 10 mm pathlengths, as well as 1/2/5/20 mm conventional pathlengths, micro-volume versions, four-way fluorescent models, stoppered sealed types, and flow-through cuvettes, they are compatible with major spectrophotometric instruments including Shimadzu, Agilent, and Persee, and support custom non-standard optical configurations.

Key applications include nucleic acid and protein quantification via OD260/280, pharmaceutical UV analysis, environmental water quality testing, heavy metal detection, photochemical reactions, fluorescence assays, academic research, and third-party testing laboratories. Each cuvette undergoes individual transmittance inspection before shipment and is individually packaged in foam protection.
