Donghai County Nivra Quartz Products Co., Ltd. supplies high-precision quartz cuvettes engineered with ultra-high chemical purity and premium optical fusion. Suitable for UV-Vis spectrophotometers, fluorescence analysis, and analytical laboratory instrumentation worldwide.
Manufactured by Donghai County Nivra Quartz Products Co., Ltd., our cuvettes utilize proprietary optical contact bonding and high-temperature fusion technology without corrosive glue. Guaranteed high structural stability, resistant to strong acids and organic solvents, offering transmission exceeding 83% at 200 nm.
Utilizing high-purity synthetic fused quartz (JGS1) to achieve superior light transmission down to deep ultraviolet wavelengths (190 nm).
Fully flame-fused and optically sintered body structure without toxic resin or adhesives. Completely chemically inert to aggressive acids and solvents.
Strict dimensional control within ±0.05 mm, matched cell optical path pairs with transmission deviation below 0.5% for precise analytical repeatability.
