Mass flow from peristaltic pumps
TESTA Analytical Solutions reports its real time flowmeter can determine average flow rate as well as peak values of pulsation, enabling selection of the most appropriate setting for any peristaltic pump application.
Peristaltic pumps are used for a wide range of applications, from simple solvent transfer to more complex flow chemistries and lab scale reactions.
Carlo Dessy, Technical Director, TESTA Analytical, commented: ‘As simple and dependable as peristaltic pumps are, they do, however, come with drawbacks intrinsic to their design and principle of operation. The flow rate cannot be determined just by the physical dimensions of the peristaltic wheel and tubing and its speed of rotation. Other factors including the viscosity of the transported liquid, flow pulsations, back pressure and ageing of the pump tubing have a significant influence.
Compact and powered via a USB connection, the flowmeter uses a thermal flow sensor that is not only extremely accurate, sensitive, and high-resolution, but is non-invasive.

Plug and play reactor modules
Uniqsis offers affordable ‘plug and play’ reactor modules designed to make high performance flow chemistry accessible.
With an operating temperature range of ambient to +300°C, the HotCoil reactor heating module represents a cost-effective entry solution into flow chemistry, simply add pumps. With LED display and ‘push-to-set’ controller, it is ideally suited to stand-alone operation. Alternatively, it can be controlled by the Uniqsis FlowSyn, Binary Pump Module, or FlowControl software.
HotChip is a standalone heater module that provides precise temperature control of flow chemistry glass static mixer (GSM) chip reactors. The Uniqsis borosilicate glass chip reactor blocks can be used as static mixers or to perform fast exothermic reactions.
The Cold Coil II flow reactor module provides an entry-level solution for low temperature flow chemistry. With an external thermoregulation circulator it can maintain stable temperatures between -78°C and +150°C for extended periods. A glass cover eliminates convective effects; a vacuum jacketed glass cover is also available.
