Micro pumps for smallest dosing volumes

Precise pumps - smart solutions. The pumps dose small and very small quantities of liquid fast and precisely. These micro annular gear pumps (mzr® pumps) make conventional dosing applications more effective and thus open up new fields of technology.

The pumps are characterized by their low weight and compact design, low pulsation, long service life, low dead volume and low shear delivery. Five series of mzr® pumps enable the smallest dosing volumes from 0.25 µl and volume flows from 1 µl/h to 1152 ml/min as well as pressures up to 150 bar.

In addition to numerous possible applications in mechanical and plant engineering, in the chemical and pharmaceutical industries, mzr® pumps perform demanding dosing tasks in laboratory and analytical technology, diagnostics, biotechnology, chromatography and further fields of application.
The pumps and dosing systems offered by HNP Mikrosysteme GmbH are made in Germany. The products are based on 20 years of experience in product development, application consulting and customer-specific adaptations and integrations.

Biochip instead of animal testing - LiquiDoS doses nutrient medium with system

New active ingredients require new tests. For ethical, economic and scientific reasons, animal experimentations are increasingly being replaced by biochips. Human cells from different organs are placed on the chips and supplied with nutrient solution via small channels. In this way, blood circulation and metabolic functions of the human body are simulated. Monitoring after the addition of active substances such as drugs, cosmetics or chemicals allows conclusions to be drawn about the reactions and processes in the human body.

The continuous supply of the cells with liquid nutrient medium is a great challenge, as even small variations influence the test results. The LiquiDoS dosing system by HNP Mikrosysteme contains a highly precise, low-shear micro annular gear pump (mzr pump), which is ideally suited for filling the biochip. Volume flows from 1.5 µl/min to 72 ml/min as well as dosing volumes from 0.25 µl are gently realized with the LiquiDoS.

In addition to the micropump, LiquiDoS contains a filter, a shut-off valve and the mzr-Touch Control. The graphical user interface facilitates the handling of the system by direct input of dosing quantity and dosing duration. Furthermore, the mzr-Touch Control enables simple programming, fast switching between manual and automated dosing tasks as well as reproducible results.
