Glass Rod for Laboratory and Industry Use

Glass rod, also called stirring rod, stir rod or solid glass rod, commonly uses borosilicate glass and quartz as material. Its diameter and length can be customized according to your requirements. According to different diameter, the glass rod can be divided into laboratory used stirring rod and sight glass used rod. Glass rod are corrosion resistant. It can resist most acid and alkali. It has strong hardness and can work in 1200 °C high temperature for long time. Thanks to these features, stirring rod is widely used in laboratory and industry. In laboratory, stirring glass can be used to speed up the mix of chemical and liquid. It can also be used to do some experiments. In industry, glass rod are used to produce gauge glass.


GR-01:Straight thin stirring rod are commonly used in laboratory.

GR-02:Glass rod with well polishing surface and edge.

GR-03:All the glass rods are produced in strict quality control system.

GR-04:All the glass rod are produced according to the International Standard and industrial standard.

Features and advantages

  • Corrosion resistance
    The glass disc especially quartz can resist acid and alkali. The quartz do not react with any acid, except hydrofluoric acid.
  • Strong hardness
    Our glass rod hardness can reach the requirements of laboratory and industry.
  • High working temperature
    The soda-lime glass rod can work in 400 °C temperature and the best quartz glass rod can work in 1200 °C temperature continuously.
  • Small thermal expansion
    Our stirring rods have small thermal expansion and it will not break in high temperature.
  • Tight tolerance
    Usually we can control the tolerance as small as ±0.1 mm. If you require smaller tolerance, we can also produce accuracy stir rod. The tolerance can be below 0.05 mm.

Application

  • Used for stirring
    In order to accelerate the mixing of the chemicals and liquids, glass rods are used to stir.
  • Used for electrification experiment
    Rubbing fur and silk can easily estimate the positive and negative electricity.
  • Used to spread liquid evenly into somewhere
    In order to avoid fierce reaction especially dangerous chemical reaction, stir rods are used to pouring the liquid slowly.
  • Used to produce sight glass
    Some large diameter glass rod are used to produce sight glass.

GR-05:Glass rods are used for stirring because of its stable chemical property.

GR-06:Pouring through glass rod can avoid fierce reaction.
