Glass labware are long-lasting and perform efficiently if they are handled with care. Keep in mind precautions that you should take when using glass labware to ensure that you never exceed the thermal shock and mechanical stress that the glass can manage because the labware will definitely break. These are the guidelines for maintaining glass labware.
All glass labware must be washed and examined to determine if they are in good condition or not before use. Washing them before use gets rid of strains of other chemicals that may react with what you want to put in the glassware because some reactions are explosive.
Dispose of defective glass labware and broken pieces using safe means. Use the appropriate means of disposing of all lab glass waste provided that the glass is not contaminated by chemicals. Types of glass are recycled separately because not all of them are compatible since their melting points vary. Borosilicate glass should never be disposed of in a domestic glass recycling stream with other glasses because they have higher melting point than other glass including soda-lime glass.
Never use etched, scratched, cracked, or chipped glass lab apparatus. Glass labware that have these defects are mechanically weak and easy to break.
It is dangerous to carry large volumetric glassware by not holding the neck or rim alone. You risk getting hurt by corrosive and toxic substances if the apparatus slip and fall because they will break and spill the contents on you. Place one of your palms at the base of the glassware and the other on the sides to offer it enough support from the base and sides.
Excessive force should never be applied when fixing a bung onto the neck of the glass labware because it can break therefore use bung that is of the right size because it will be quick and easy to fix.
Never use stirring rods that have sharp ends when stirring solutions in the glassware. The glassware can be scratched by the sharp edges that are on the stirring rods hence weakening the apparatus.
Glass lab apparatus should never be exposed to sudden changes in temperatures and glass for they break quickly under these circumstances. Avoid thermal shock that is caused by sudden changes in temperature by heating the apparatus gently and increase the temperature gradually. The apparatus should be cooled slowly after they have been heated. Use clamps that do not over tighten the mouth of the glassware to prevent too much pressure from accumulating in the vessel and remove the clamp gently to release the pressure slowly.
