Peristaltic & dosing pumps

In a peristaltic pump, rollers squeeze a flexible tube, so the liquid only touches the tubing. That keeps the pump clean, suits sterile and aggressive liquids, and lets you change media simply by changing the tube; see silicone tubing for suitable tubes. The pump can run continuously or dose set volumes. A dosing pump delivers a fixed volume per stroke, which suits repeated additions of the same amount, for example from a bottle or canister. Choose peristaltic for flow and flexibility, a dosing pump for simple fixed portions. Tell us your liquid and volumes: sales@luminixhealth.com.

On a peristaltic pump, the flow rate depends on three things: the pump head, the speed and the inner diameter of the tubing. A wider tube moves more liquid per turn; a narrower tube gives finer control at low flow. The maximum flow, usually in ml/min, is in the product title or on the product page; choose a pump whose range covers your need with some margin. Multi-channel heads dose the same liquid into several lines in parallel. Tubing in many diameters is in silicone tubing. Send us your target flow and we will suggest pump and tubing: sales@luminixhealth.com.

Two things decide: fit and material. The inner diameter and wall thickness must match the pump head, otherwise the rollers do not seal or wear the tube too fast; the product page of the head states which tubing it takes. Then choose the material for your liquid: silicone is flexible and suits aqueous and biological media, see silicone tubing; for solvents and aggressive chemicals, look at other materials in PVC, PTFE and other tubing and check their suitability for pumping on the product page. Replace tubing when it flattens. Questions? Ask sales@luminixhealth.com.

If you already have a drive unit, a matching pump head is the economical way to add channels, change tubing size or replace a worn head. Heads only fit the drives they are made for, so check compatibility on the product page, or send us the model of your drive and we will confirm. If you are starting from scratch, a complete pump with drive, head and control is simpler: everything is matched and ready to use. In both cases, order suitable tubing at the same time, for example from silicone tubing. Send us your drive model: sales@luminixhealth.com.

A peristaltic pump moves liquid by rollers squeezing a tube, so the liquid never touches the mechanism. Flow depends on the tube bore and the speed. A dosing pump aims at a set volume. The tube is the consumable, and the chemical has to be one that tube survives.

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.
