Description
Boiling stones grade A, specially for vacuum distillation, packs of 250 g are inert laboratory aids used to promote smooth boiling and prevent bumping during distillation under reduced pressure. These stones are added to the distillation flask to provide nucleation sites that ensure even vapour formation and safer operation when working with vacuum systems. The grade A material is selected for vacuum distillation applications where controlled boiling behaviour is critical. Available from manufacturer Hecht in practical 250 g packs, the product supports repeated use across multiple distillation runs in organic synthesis, solvent recovery and analytical sample preparation. Laboratories rely on boiling stones to maintain steady reflux and reduce the risk of sudden eruptions that can compromise yields or safety. The 250 g pack size offers convenient stock for routine and research-scale work. Simply introduce a few stones into the boiling flask before heating under vacuum to achieve reliable performance throughout the distillation process.

Questions about Boiling stones, grade A, for vacuum distillation, packages of 250 g
What is this article?
Boiling stones, grade A, for vacuum distillation, packages of 250 g is the article on this page. Luminix Health distributes Hecht for laboratory use. It sits in Distillation heads, adapters & columns, inside Distillation & extraction glassware, in Labware.
A still head, an adapter or a column is the glass between the boiling flask and the condenser. A Vigreux or packed column gives the vapour a surface so a closer-boiling mixture can separate. The joint sizes at both ends have to match the flask and the condenser.
Distillation separates liquids by boiling point. A condenser turns the vapour back into liquid: Liebig, coil and cold-finger shapes differ in how much cooling surface they offer. A still head and a column sit between the flask and the condenser. A Soxhlet extractor washes a solid again and again with the same solvent. Ground joints have a standard size, and the joint, not the flask, is what has to match. The pieces are indexed under ISO laboratory glassware.
