1.Glass instruments made with the excellent properties of glass are widely used in various laboratories such as chemical laboratories, medical laboratory, biological laboratory, scientific research laboratory and teaching laboratory.
2. Potassium borosilicate glass has a very low coefficient of thermal expansion, about one-third of ordinary glass, and can withstand temperature changes of about 200 ℃.
3. It is a kind of low alkali high borosilicate glass, does not contain calcium, magnesium, zinc and lead, has better physical and chemical properties, strong resistance to chemical corrosion, used in the production and processing of heat-resistant glass instruments and other demanding utensils.
Over the past 20 years, we have gained the trust and support of many customers. Our company has established close cooperative relations with many world famous brands, providing high-quality products and pre-sales and after-sales services for the scientific research and development of all walks of life.
