Glassware Questions & Answers

The best way to avoid breakage, and therefore ensure your safety, is to avoid mechanical stresses to the glass and ensure stability by supporting the components. To minimize stresses and vibrations, use something like PTFE bellows.

For volumetric accuracy, remember that brands vary. Be very careful that your measuring instrument is valid, measuring what it is meant to measure. Make sure that you choose a brand that is consistent in the way in which it constructs joints to ensure proper sealing.

The brand should be able to replicate multiple items according to industry standards. Choose the glass that has a uniform thickness of the wall. This will result in better durability.

It is important to follow safety protocols at all times, not only when you are working with glass. Always wear safety goggles to prevent eye irritation and even blindness if an accident occurs.

When working with corrosive chemicals, wear latex gloves to protect your hands. In fact, latex gloves are recommended for all lab work. In case of splashing or spillage, wear a laboratory coat or apron, and always wear closed shoes to protect your feet.

Many glass products have been especially designed for use in the laboratory.
