Investigating Variation in Flow from Peristaltic Pumps

With peristaltic pumps, several flow paths can be operated simultaneously. However, many parameters influence the actual flow rate in each channel. Accurate determination of the individual flow rate in the individual channels is crucial for reproducible results.

Investigating Variation in Flow from Peristaltic Pumps

Peristaltic pumps find wide application in modern labs, they are considered inexpensive, easy to use and to maintain and, most important of all, are extremely reliable and flexible. The range of application is huge, from simple transfer of a liquid from one container to another in HPLC and Ion chromatographs, to more complex usage as dispensing tools for reagents in flow chemistry.

The Importance of Understanding Pump Flow

Pumps are one of the most common tools enabling liquids to be moved, delivered, pushed through a separation column, supplied as a dose or transferred from one container to another. Several different pumping technologies are available to choose from, depending on your application or problem. As you might expect - a pump designed to pump crude oil through a pipeline has very different requirements compared to a pump designed to deliver a constant stream of medication into a patient's vein. As such, the term ‘flow’ can be interpreted very differently, depending on the context.

Alles stabil und im Flow?

Mithilfe von peristaltischen Pumpen lassen sich mehrere Förderwege gleichzeitig betreiben. Doch viele Parameter beeinflussen die tatsächliche Durchflussrate in jedem Kanal. Die genaue Bestimmung des individuellen Durchflusses ist für reproduzierbare Ergebnisse entscheidend.

Real-Time Monitoring of HPLC Pump Performance

High Performance Liquid Chromatography (HPLC) is nowadays one of the most widely used techniques in analytical chemistry. The range of applications soluble using HPLC covers a vast range of sample types, concentrations, and compositions. This extreme flexibility is achieved by using specific columns carefully designed for each particular investigation...Read More
