Anti-bumping granules, also known as boiling stones or boiling chips, are essential lab accessories used to prevent or minimize the occurrence of bumping during the heating of liquids. These small granules are typically made of inert materials such as porous ceramics or glass beads.

When added to a liquid being heated in a flask or other glassware, they create nucleation sites that promote the formation of small bubbles. These bubbles help to regulate and distribute the heat more evenly, preventing the rapid and uneven boiling that can lead to bumping or violent boiling.

By introducing anti-bumping granules into the liquid, the risk of splattering, loss of sample, or equipment damage due to excessive bumping is significantly reduced. Anti-bumping granules are commonly used in various laboratory applications, such as distillation, reflux, and other heating processes where precise and controlled boiling is crucial.

They are a valuable tool for enhancing safety and improving the reliability of heating operations in the lab.
