Description
Woulff bottle (new Hei-VAP series) is a condensate separation accessory designed to protect the valves of the vacuum pump during rotary evaporation. It is intended for use with standard vacuum laboratory bottles and features a screw connection that simplifies emptying and cleaning between runs. The bottle has a filling volume of 200 ml and is compatible with all Hei-VAP configurations in the new series. Supplied as a single piece from manufacturer Heidolph, it integrates into laboratory vacuum lines as a protective intermediate vessel. Net weight is 0,420 kg and gross weight is 0,540 kg; packaging measures approximately 0,21 m depth, 0,20 m width and 0,11 m height, corresponding to a packaging volume of 0,005 m³. Classified among accessories for evaporation equipment, this Woulff bottle supports condensate capture ahead of the pump, helping safeguard valve components while remaining straightforward to service thanks to the screw connection and standard-bottle interface across Hei-VAP setups.

Questions about Woulff bottle (new Hei-VAP series)
What is this article?
Woulff bottle (new Hei-VAP series) is the article on this page. Luminix Health distributes Heidolph for laboratory use. It sits in Rotary evaporators, inside Pumps, vacuum & evaporation, in Lab instruments.
A rotary evaporator spins a flask under vacuum so solvent boils off a sample at a modest temperature. The flask size, the condenser type and the vacuum the seal can hold are the specification. Bumping is a flask that was too full or a vacuum that arrived too fast.
A vacuum pump lowers the pressure above a liquid so it boils at a lower temperature. That is the point of a rotary evaporator: solvent leaves a sample without cooking it. A diaphragm pump or a rotary-vane pump is chosen by the vacuum it reaches and by whether solvent vapour will destroy it. A peristaltic pump moves liquid by squeezing a tube, so the liquid touches only the tube. A barrel pump transfers a larger volume from a drum. The glassware on the evaporator is indexed under ISO laboratory glassware. Solvent identity is on PubChem.
