·Products
It is compatible with spectrometers for both quantitative and qualitative analysis. The cuvettes can be categorized into three main series based on the wavelength range: visible light series, UV-visible light series (quartz cuvettes), and infrared series (infrared cuvettes).
·Function
1) High mechanical strength, excellent adaptability to temperature changes, and a firm adhesive joint that can withstand high pressure.
- Advanced optical processing technology ensures excellent optical properties of transparent surfaces, with component composition errors ≤ 0.3%
- Made from high-quality quartz and optical glass, ensuring no bubbles or streaks. Quartz cuvettes have transmittance over 80% at 200nm, while glass cuvettes have over 80% at 340nm.
- Low melting point glass is used to seal the interface, providing strong corrosion resistance. It can withstand 6mol/L sodium hydroxide, 6mol/L hydrochloric acid, absolute ethanol, carbon tetrachloride, and benzene for 24 hours without adhesive failure or leakage.

Low Temperature Scouring and Bleaching
Low temperature scouring agent relates to the pretreatment process of printing and dyeing industry. The invention is scientifically prepared by efficient surface active agent and effective chemical additives, and can complete desizing, boiling and bleaching treatment of cotton and linen, chemical fiber and blended fabric at 45℃ ~ 60℃ for 1 hour, effectively remove the size, cotton seed shell, pigment and impurities on the surface of the fabric, improve the whiteness of the fabric, and almost do not damage the fiber. The invention has the advantages of energy saving, short process flow, improving quality and reducing labor intensity of workers, and has obvious economic and social benefits.
