Feeding range, accuracy, suitability for certain media properties such as viscosity and media compatibility are typical selection criteria for laboratory pumps.
Our LabDos peristaltic pumps use stepper motor technology which allows them to run at extremely slow speeds without any problems. This allows you to precisely control the flow rate, especially at low flow rates, while also increasing process reliability.
Our pumps are positive displacement pumps, where the medium only comes into contact with the pump tube. This ensures contamination-free pumping. The media resistance depends on the hose material used, so there is a solution for almost every application.
They are particularly suitable for:
With a wide range of applications, high precision and an excellent price-performance ratio, LabDos pumps meet a variety of requirements in the laboratory. They are the perfect choice for stand-alone use as well as for operation in automated systems,.
