Peristaltic Pumps
Feeding range, accuracy, suitability for certain media characteristics such as viscosity and media compatibility are typical selection criteria for laboratory pumps. The LabDosTM laboratory pump perfectly meets these varied requirements and is good value for money. It is thus the ideal solution for diverse applications: A dosing pump for laboratory process plant, for feeding and recycling, for automatic sampling and for liquid handling applications.
The trend-setting SofDriveTM drive technology combines the advantages of a servomotor with those of a stepping motor. The drive has the sturdiness, extremely large rotational speed range, absolute precision and long service life of a stepping motor but does not demonstrate its pulsating performance. The SofDriveTM drive forms an ideal pairing together with pump heads from Watson Marlow and Masterflex.
Large operating keys with tactile feedback enable sure operation, even when wearing gloves. The illuminated screen can be faultlessly read from any angle. The pump is suited both for stand-alone use and for operation in automated systems.
The simple working principle of the peristaltic pump enables its cost-effective deployment from simple feeding jobs up to complex liquid handling.
The pump head, which is fitted onto the slanted front, enables the hose to be replaced in a few quick steps without having to dismantle the pump.
