Not all glass is created equal, and borosilicate glass is a step above the rest when it comes to laboratory glassware.  Borosilicate refers to a group of hard glass compounds which has silica and boron trioxide as its main glass-forming components. Generally, three types of laboratory glassware are used but for several reasons’ borosilicate glass is preferred for laboratory applications.

What makes Borosilicate 3.3 glass superior?

1.  Thermal stability:

Borosilicate glass has an impressive ability to withstand temperature fluctuations and thermal shocks. This is due to its remarkably low linear coefficient of expansion at approximately 3.3 x 10-6 K-1.

2.  Chemical resistance and stability:

Borosilicate glass has good resistance to concentrated acids and alkaline solutions which may potentially damage laboratory glassware items.

3.  Convenience:

Unlike Soda lime glass, Borosilicate 3.3 is durable glassware that is dishwasher safe and can withstand autoclaving. This feature saves you from the tedious task of manually washing your glassware.

4.  Spectral Transmittance:

Increased light transmittance and high-level transparency makes borosilicate glass tubing the preferred material for chemistry glassware such as test tubes, glass beakers and funnels. Photochemical reactions can also be easily observed as the glassware allows for the permeability of UV-rays.

5.  Longevity and affordability

All the physical properties of borosilicate 3.3 glass allow glassware products made from this material to be used over longer periods of time, especially when compared to lower quality glass available in the glass consumable industry.

When purchasing glassware products for your lab, you should look out for the abovementioned qualities to ensure functionality and durability. Borosilicate 3.3 glass stands apart from the rest and is the material of choice for Glassco glassware supplied by Lasec®.
