Description
RZ 2.5 is a two-stage rotary vane pump intended for laboratory vacuum applications and rated for 230 V / 50-60 Hz operation. The instrument is fitted with a CH power cable to suit Swiss laboratory electrical connections. This two-stage pump from manufacturer VACUUBRAND replaces the earlier article number 20698121 and offers proven rotary vane vacuum generation in a compact format. Net weight is 14.9 kg and gross weight is 16.8 kg, underscoring a durable build appropriate for regular laboratory service. Produced in Germany, the RZ 2.5 meets the needs of vacuum processes that call for reliable two-stage rotary vane technology. The 230 V / 50-60 Hz electrical rating aligns with standard laboratory supplies, and the CH cable provides regional compatibility. Delivered as 1 pc, the pump constitutes a self-contained vacuum source ready for integration into existing setups. Laboratories requiring a clearly defined two-stage rotary vane pump with Swiss power connection will find this model a practical and precisely specified choice.

Questions about RZ 2.5, CH
What is this article?
RZ 2.5, CH is the article on this page. Luminix Health distributes Vacuubrand for laboratory use. It sits in Vacuum pumps, inside Pumps, vacuum & evaporation, in Lab instruments.
A laboratory vacuum pump lowers pressure for filtration or evaporation. A diaphragm pump tolerates solvent vapour better than an oil-sealed rotary vane pump, and it reaches a milder vacuum. The ultimate vacuum and the flow, and whether the wetted path survives the solvent, are the choices.
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.
