Learning The “Secrets” of
Glass labware are long-lasting and perform efficiently if they are handled with care. Do not expose the glassware to thermal shock and mechanical stress that is beyond the limit that the glass can handle by adhering to safety measures to prevent them from breaking. 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.
Use safe ways of disposing of defective glass lab equipment and broken pieces of these apparatus such as throwing them in a purpose-designed disposal bin that is clearly labeled and is resistant to puncture. If the glass is not contaminated by harmful chemicals, use the appropriate method of disposal. Glass of different types have different melting point thus they are not compatible and cannot be recycled together. 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.
Avoid using etched, scratched, cracked, or chipped lab glassware. When glass lab apparatus have they defects they are weak mechanically and are highly susceptible to breakage.
It is dangerous to carry large volumetric glassware by not holding the neck or rim alone. You should protect yourself from spills of corrosive and toxic substances that you are carrying in those apparatus by handing the apparatus carefully because if they slip and fall, the contents will spill on you.Support the base of the apparatus and the sides with your palms.
Use bung that is of the appropriate size for you to quickly and easily fix it onto the neck of the glass lab apparatus because when you use too much force, you can break the apparatus.
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.
Exposing glass labware to sudden temperature and pressure changes increase the risk of breakage. Avoid thermal shock that is caused by sudden changes in temperature by heating the apparatus gently and increase the temperature gradually. Cool the apparatus slowly. 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.
