Glass is inert, temperature tolerant and resistant to chemical corrosion, making it a staple in laboratories. General glass tolerances for freezing to heating “guidelines” are that you should only heat frozen glass at a rate of approx. 20 degrees Celcius or less per minute to prevent it from breaking, or a minimum of 5 minutes to bring a freezing container up to boiling.
If your procedures require you to move glass from the freezer to a hot place, remember to allow the temperature to ramp up slowly and you will minimize lab mishaps and chemical spills.
