DWK safety tips and tricks - heating laboratory glass

Heating glassware is an important topic as heat can change the volume of the glassware if the temperature used is too high. The maximum temperature for heating the glass depends on the specifications and what type of glass is used. For example, borosilicate glassware provides a lower coefficient of expansion than other glass types such as soda lime glass. Another note is that not all glassware...

What gives Pyrex glassware its advantages?

Pyrex® is borosilicate glass which differs from other glass types as it possesses unique properties of high resistance to chemical exposure, thermal expansion and thermal shock.  This has advantages in laboratory uses, a key one being where glassware is directly heated, in beakerstest tubes or flasks. Let's look at some of these properties in more detail and see their advantages.
