Description
Pump head DG4B is a multi-channel peristaltic pump head with 4 channels and 10 rollers, designed for flow rates up to 54 ml/min. Tubing with a wall thickness of 1 mm and an inner diameter of 1–3 mm can be installed in the head, ensuring secure fit and stable tube contact during operation. The elevated roller count produces particularly low pulsation, which is advantageous for applications that benefit from smoother fluid delivery. Its four-channel arrangement supports parallel dosing, sampling, or multi-line transfer in laboratory and process settings. This pump head from manufacturer Landgraf HLL is built for use with compatible peristaltic pump drives in research, analytical, and routine laboratory workflows. The combination of ten rollers and moderate maximum flow helps reduce flow ripple while maintaining multi-channel capability. Suitable for aqueous and other compatible media where controlled, low-pulsation transfer is preferred. Supplied as a single piece ready for mounting on matching pump systems in fluid-handling installations.

Questions about Pump head DG4B, 4 channel, 10 rollers, up to 54 ml/min
What is this article?
Pump head DG4B, 4 channel, 10 rollers, up to 54 ml/min is the article on this page. Luminix Health distributes Landgraf HLL for laboratory use. It sits in Shakers, rockers & rotators, inside Stirring, shaking & mixing, in Lab instruments.
A shaker, rocker or rotator moves a rack, a plate or a bottle so the contents keep moving without a stirrer bar. Orbital, reciprocating and rocking motions are different. The platform, the load and the speed range are the specification.
Stirring keeps a mixture uniform or helps a solid dissolve. A magnetic stirrer spins a bar inside a closed vessel. An overhead stirrer drives a shaft when the liquid is viscous or the volume is large. A vortex mixer agitates a tube. A shaker moves a whole rack or a plate. The shape of the impeller and the speed decide whether the liquid turns over or merely spins. The vessels being stirred are indexed under ISO laboratory glassware.
