Distillation and synthesis components

The components important for distillation are divided into distillation towers, distillation bridges, connecting pieces, columns, coolers and cold traps, vacuum feeds and distillation trays. The apparatuses, which are assembled by means of standard ground joints, allow a flexible design. Coolers are supplied with water via olives or cooling liquids via circulating coolers. Glass can be repaired or adapted by laboratory glassblowers on request.
