When talking about medium borosilicate glass bottles, we have to mention borosilicate glass. It can be said that medium borosilicate glass bottles are just one of the categories of borosilicate glass. Low borosilicate glass also counts, but there are differences between the two. The main difference between the two is that it has a higher content of boron trioxide, has higher thermal and chemical stability, and has a stronger ability to withstand temperature changes. Therefore, the resulting medicine bottles also have certain performance differences.

The national standard for water resistance on the inner surface of low borosilicate vials is 2.6m, and the national standard for water resistance on the inner surface of medium borosilicate vials is 1.3m. In simple terms, “water resistance” is the harmful alkaline oxides such as potassium and sodium adsorbed on the inner wall of the vial during subsequent processing in the bottling plant. The fewer oxides, the better the water resistance. Good water resistance affects the pH, clarity, Various indicators such as stability are relatively good.

The size tolerance of medium boron vials is very small. For example, the outer diameter tolerance standard of 16 tubes is plus or minus 0.14m, the color is crystal clear, and the strength is also very high, which is better matched with production equipment. The tolerance of low borosilicate is large and unstable between batches. For example, the outer diameter tolerance standard of 16 tubes is plus or minus 0.14m, the color is crystal clear, and the strength is also very high, which is better matched with production equipment.
