Quartz and Glass Cuvette
·Product Description
This product is compatible with spectrometers for both quantitative and qualitative analysis. It can be categorized into three series based on the wavelength range: visible light series, UV-visible series (quartz cuvette), and infrared series (infrared cuvette).
·Product Features
1. High mechanical strength and excellent thermal resistance. The adhesive parts are firm and can withstand various atmospheric conditions.
2. Advanced optical processing technology ensures superior optical properties of the transparent surface. The component error is ≤0.3%.
3. Made from high-quality quartz and optical glass to ensure no bubbles or streaks. The quartz cuvette has over 80% transmittance at 200nm, while the glass cuvette exceeds 80% at 340nm.
4. Uses low melting point material to seal the interface, offering strong corrosion resistance. It can endure 6mol/L sodium hydroxide, 6mol/L hydrochloric acid, absolute ethyl alcohol, carbon tetrachloride, and benzene for 24 hours without adhesive failure or leakage.Â
