Why chemistry labs need expert glassblowers
By Oli Usher, on 11 September 2015
Chemistry labs need skilled glassblowers to produce some of the intricate, bespoke glassware for some of their experiments. This item, produced by one of UCL’s glassblowers, is designed to be placed on a heat source so it can distill liquids and deposit them in ampoules along its long stem.
The flask’s design includes bell-shaped edges inside to encourage the liquid to evaporate evenly. The gas then cools and condenses inside the long stem, collecting at the end. When enough has collected there, the end of the stem can be melted off, sealing the liquid safely inside.
