A 10-Point Plan for (Without Being Overwhelmed)

Precautions to Take to Elongate the Lifespan of Glassware Lab Apparatus

You should take great care of your lab glass vessels for them to elongate their lifespan and enable them to perform efficiently. 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 tips that will enable lab glassware to last long.

All glass labware must be washed and examined to determine if they are in good condition or not before use. You never know if the strains of chemicals from experiments that you did before were rinsed from the apparatus and the chemicals that you want to put in the apparatus may have exothermic reactions with those chemical strains.

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. Glass of different types have different melting point thus they are not compatible and cannot be recycled together. The melting point of borosilicate glass is higher melting point than other glass including soda-lime hence do not dispose of borosilicate glass with other glasses in a domestic glass recycling stream.

Glass lab instruments that are etched, scratched, cracked, or chipped should never be used. 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. If they slip and fall, they will not only break but also spill corrosive and toxic substances on you if that was the contents. 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. Sharp edges on the stirring rod can scratch the glass labware and weaken its mechanical strength.

Do not expose the glass lab vessels to sudden pressure and temperature changes because that will make them break. Heating the apparatus gently and increasing the temperature gradually will prevent thermal shock that is caused by sudden changes in temperature. The apparatus should be cooled slowly after they have been heated. Do not use over-tightening clamps and release pressure from the apparatus slowly by opening the clamp gently.
