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.

Four pieces of stirring rod with clear surface.
GR-01: Straight thin stirring rod are commonly used in laboratory.Two piece of large glass rod with clear surface.
GR-02: Glass rod with well polishing surface and edge.
A hand is measuring rod diameter of glass rod with digital vernier caliper.
GR-03: All the glass rods are produced in strict quality control system.A hand is measuring glass rod length with meter ruler.
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.
A piece of stirring rod is stirring the liquid in the beaker.
GR-05: Glass rods are used for stirring because of its stable chemical property.Pouring the liquid into the glassware through stir rod.
GR-06: Pouring through glass rod can avoid fierce reaction.
Package and transportation of glass rod

Packed with bubble wrap and then carton and wooden case outside.
As customers' requirements.
glass rods are packed in carton and wooden cases.
GR-07: Our glass rods packed with bubble wrap and then carton and wooden case outside.
