Ultra trace colorimetric dishes are used to hold reference and sample solutions. Paired with spectral analysis instruments, it can perform quantitative and qualitative analysis of substances, and is widely used in industries such as chemical, metallurgical, medical, pharmaceutical, food, environmental protection, power plants, water plants, petroleum, and other sectors, departments, colleges, and research institutions for testing and laboratory analysis.
Select quartz glass and optical glass to ensure no bubbles or stripes. The quartz colorimetric dish has a wavelength greater than 80% at 200nm, and the glass colorimetric dish has a wavelength greater than 80% at 340nm. Using low melting point glass sealing, it has strong corrosion resistance and can withstand corrosion in five media including 6mol/L sodium hydroxide, 6mol/L hydrochloric acid, anhydrous ethanol, carbon tetrachloride, and benzene for 24 hours without delamination or leakage.
