Description
Single-channel pump head SP vario is a laboratory peristaltic pump head for precise single-channel fluid transfer with adaptable tubing fit. Its rotor offers adjustable roller spacing so occlusion can be matched to the hose wall thickness (SWS), supporting consistent performance across different tubing grades. Convex rollers help prevent damage to organic cell cultures during gentle pumping. Sealed ball bearings support smooth running, while the rollers are stainless steel and the roller carrier is coated aluminium for durability in routine use. Depending on the drive unit and tubing selected, flow rates between 2,0 and 4151 ml/min are attainable. This pump head from manufacturer Heidolph is supplied as one piece and is intended for laboratories that need reliable single-channel dosing, media transfer or culture-friendly fluid handling. The combination of adjustable rollers, sealed bearings and robust materials makes it suitable for routine and specialised peristaltic applications when paired with a compatible drive in research or process environments.
This article belongs on Vacuum pumps, in Pumps, vacuum & evaporation.

Questions about Single-Channel Pump Heads SP vario
What is this article?
Single-Channel Pump Heads SP vario is the article on this page. Luminix Health distributes Heidolph 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.
