Borosilicate & Pyrex Glass

1. Borosilicate Pyrex Glass

Borosilicate glass is typically formed from silica and boron oxide constituents. Borosilicate glass has a very low thermal expansion coefficient which makes it more resistant to thermal shock than any common glass.

Borosilicate also has a high softening point of 820 deg C. It has excellent resistance to water, acids, solvents and halogens. However, high concentrated acid such as hydro fluidic acid and alkaline solutions will corrode the glass rapidly.

Application: Borosilicate is used for virtually all modern laboratory glass ware.  This is because of its chemical thermal resistance as well as optical clarity.

Borosilicate is a cheaper and easier alternative to fused quartz.  Borosilicate is also used for kitchenware where measuring cups feature screen printed markings for precise measurements, e.g. measuring glasses. Other uses include:

  • HD lamps

  • Guitar slides

  • High quality flashlights


Working temperature is 400 degrees C

​2. Ribbed Borosilicate Glass

This is used mainly as a spreader lens for lighting.

3. Pattern Pyrex Glass

This is used for diffusing light.

4. Borosilicate Tubing and Rods

Borosilicate rods and tubing are perfect for laboratory equipment and specialist uses, this is because they are exceptional strong and able to with stand high temperatures.

Application: Rods are ideal for solid stairs because of its ability to withstand high heat.
They can be made into a wide range of sizes and shapes with minimal cost.

Tubing is ideal for uses in laboratory experiments for passage for liquid or gases. Like the rods, tubing can also be made into a wide range of sizes and shapes with minimal cost.

Both rods and tubing can be made with a variety of finishes, including sandblasting and can be coloured, drilled or polished.
