Description：
Glass capillary tubes also called Micro glass capillary ,small hole capillary glass，precision glass tube.Usually the out diameter less than 10mm.
Micro quartz glass capillary tubes and rods are made of high purity silicon dioxide in thermal processing method. The tubes and rods are drawn at one time, dimension and tolerance are uniform which in high precision, good tolerance control.
All products adhere to the most exacting tolerances in a full spectrum of sizes, materials and shapes.
Type：
According the shape, it is divided into circular glass capillary tube, square glass capillary tube, triangular glass capillary tube, thick-walled glass capillary tube, thin-walled capillary tube, double-hole capillary tube, porous capillary tube, and other special-shaped capillaries,D shaped capillary.
According the material，it is divided into micro quartz capillary tube，borosilicat glass capillary，soda lime glass capillary，lead free glass capillary.
According to dimensional accuracy，it is divided normal glass capillary with large tolerance （such as ±0.1 to ± 0.5mm）and high precision micro glass capillary tubes with tight tolerances（Such as ±0.001mm）

Different of borosilicat glass capillary and quartz capillary .
1.Different ingredients
High borosilicate glass capillary composition oxidation sodium silica, boron oxide and boron silicon content is higher in the sheet glass: 12.5 ~ 13.5%, silicon: 78 ~ 80%.But quartz glass capillary is made of silica and the content is 99.99.
2. Different temperature tolerance:
The temperature of high borosilicate glass capillary is 520 degrees and the softening temperature is 820 degrees.
The temperature of quartz glass capillary is 1100 degrees and the melting point is about 1700 degrees.
3.Quartz glass capillary is not only resistant to high temperature, but also to acid and corrosion.
