Transparent Borosilicate Sealed Jar

The raw material of transparent borosilicate sealed jar is borosilicate glass. Its main components are sodium hydroxide (Na₂O), boron oxide (B₂O₃) and silicon dioxide (SiO₂). The boron content is about 12.5%-13.5%, the silicon content is 78%-80%, and the ferrous ion content is very low. Therefore, the appearance is clear and transparent, very refreshing, and there is no need to open the jar frequently to check the remaining amount. It is equipped with a sealing rubber ring during production. After the lid is closed, the rubber ring will fit tightly to the mouth of the jar to form an enclosed space, which can effectively block the outside air and prevent the smell of the items. The transparent appearance gives people a high-end and exquisite feeling. Put it in the kitchen or on the dining table to enhance the beauty of the entire home.

Due to its chemical composition, high borosilicate glass has excellent performance in heat resistance and chemical stability. It is for this reason that transparent borosilicate sealed jars have good performance advantages:

High and low temperature resistance: It can withstand temperature differences of -30℃-200℃. Compared with ordinary glass, ordinary glass can only withstand a temperature difference of 70℃. Therefore, friends who like to drink hot water should give priority to high borosilicate glass cups;

Pollution resistance: The surface is smooth and not easy to absorb impurities. It is easy to clean and can be used for laboratory utensils;

Light transmittance: The light transmittance is ≥‌92%, which is close to crystal transparency. The items inside can be seen, and the ultraviolet blocking rate is >90%;

Safety and environmental protection: The lead content is 0, and it has passed quality certification. It can be used to store food and can be eaten immediately after opening the lid, which is in line with people's concept of putting safety first.
