Distilling receivers, acc. to Bernhauer

Distillation receivers according to Bernhauer, 50 ml are specialised laboratory glassware assemblies intended for controlled collection of distillate fractions. Each set includes a suction olive and is supplied complete with three round-bottom flasks of 50 ml capacity, all fitted with NS 14/23 ground joints together with a matching NS 14/23 socket. This configuration supports sequential fraction collection under atmospheric or reduced-pressure conditions and integrates readily with standard distillation trains. The Bernhauer layout is widely used in organic synthesis, solvent recovery and purification workflows where multiple cuts must be isolated cleanly. Offered by manufacturer Witeg, the receivers provide a ready-to-use solution that eliminates the need to source individual flasks and adapters separately. Net weight is 0,158 kg, allowing convenient handling and stable placement on laboratory benches or distillation racks. Typical applications include preparative organic chemistry, natural-product isolation and teaching laboratories that require reliable joint compatibility and vacuum-assisted transfer via the olive. The complete three-flask package ensures immediate deployment for multi-fraction experiments while maintaining the dimensional standards expected of precision laboratory glassware.
