Description
Special adapter for rotary evaporators for screw-thread vials 15-50 ml permits distillation directly from storage vessels without intermediate transfer. The assembly consists of a centred sleeve NS 29/32 for mounting on the vapour duct tube and a double screw piece of PVDF fitted with an internal sealing ring of FKM PTFE transparent coated. This arrangement accommodates screw-thread storage vessels of 15 ml, 20 ml, 30 ml and 50 ml. Supplied by manufacturer Rettberg, the adapter facilitates efficient laboratory evaporation procedures by allowing samples to remain in their original containers throughout the process. It is designed for rotary evaporator installations that demand accurate fitting of medium-volume threaded glassware. Centred geometry promotes balanced rotation under vacuum conditions. The accessory is appropriate for analytical and preparative applications where minimised handling improves throughput and sample integrity. Net weight measures 0,054 kg. Product type is adapter and country of origin is Germany.
This article is part of Rotary evaporators, in Pumps, vacuum & evaporation.

Questions about Special adapter for rotary evaporators for srew thread vials 15 - 50 ml
What is this article?
Special adapter for rotary evaporators for srew thread vials 15 - 50 ml is the article on this page. Luminix Health distributes Rettberg 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.
