what is the difference? Borosilicate glass vs Soda Lime glass vs Pyrex
Lots of lab glassware states the type of glass it is made of – Pyrex, Borosilicate Glass or Soda Lime.
What is the difference between these types of glass?
Different types of glass have different chemical compositions, meaning Borosilicate glass and Pyrex are better suited to heating.
Borosilicate glass has a higher porportion of silicone dioxide than Soda Lime glass, as shown on the table below;
This difference means that Borosilicate glass does not expand as much on heating, so it is less likely to break when heated.
Pyrex is one particular blend of Borosilicate glass, with a particularly high heating tolerance.
Soda Lime glass is sometimes used for glassware which is not likely to be directly and strongly heated, for example petri dishes or TLC chromatography tanks.
Borosilicate glass or Pyrex is usually used for glassware that may be directly heated, such as beakers or boiling flasks.
