Low Flow Resistance 15 Ml Glass Vials Alkali Resistant Mini Glass Vials

Easy To Clean Glass Tube Vials Low Flow Resistance

Procuct

Glass is a non-metal tube, is sodium oxide (of Na2O), boron oxide (of B2O3), silicon dioxide (SiO2) glass as a base component. Its good performance has been widely recognized by the world community, compared with ordinary glass, harmless side effect, the nature of their mechanical properties, thermal stability, resistance to water, alkali, acid, etc. is greatly improved, it can be widely used in chemical, aerospace all areas of military, families, hospitals, etc., with good promotional value and social benefits, this type of glass appeared in our country is another new revolution in basic materials industries.

1. Ordinary glass, such as laboratory use;

2. The glass tube is made of chemicals commonly used thermal stability and good corrosion resistance borosilicate glass. Transparent, easy to clean, flow resistance is small, inexpensive. But the pressure resistance is low and it is easy to damage. Can be used to -30 ~ + 130 ℃, rapid temperature change does not exceed 80 ℃ occasions.

3. Neutral glass tube

4. borosilicate glass tube

principle

The purpose is to eliminate permanent stress and structural imbalance in glass products. Glass is a poor thermal conductor. After the product is formed, the surface layer and the inner layer will have a temperature difference during the cooling process. When the surface layer is solidified and the inner layer is viscous, the temperature difference exists but the stress relaxation does not exist. This temperature difference occurs when the surface layer is cooled to room temperature. , The inner layer continues to cool down and shrinks, which is hindered by the surface layer to produce tensile stress, and at the same time, the surface layer produces compressive stress, which is permanent. The size and distribution of the permanent stress caused by the thermal process in each part of the product will not be uniform, therefore, it will affect the strength of the glass product, and even break by itself due to stress concentration. Annealing can eliminate harmful tension inside the glass and prevent new stress from being generated.
