• Safely and precisely delivering ammonia solution (Feb 17, 2021)

  Micro pumps continuously feed aqueous ammonia into static mixers

  A continuous mixing unit consisting of several static mixers is supplied with eight liquids of different viscosities. Micro annular gear pumps of the hermetically inert series and the high-performance series from HNP Mikrosysteme are used for the smaller volume flows of highly corrosive liquids. Aqueous ammonia (NH3 25 % aq.) is a special technological challenge. Here the hermetically inert pump mzr-6355-cs works in a material combination of ceramic and stainless steel. In this application, the micro pump delivers volume flows between 4 and 7 ml/min.

  The system produces mixtures with different polymer concentrations. The volume produced is controlled based on the customer's daily delivery requirements. The continuous mixing system is fully automated. It can be easily connected to the site's local IT systems, such as SAP. Continuous and highly precise delivery with micro annular gear pumps thereby ensures a process that is fast, flexible and safe.

• Biochip instead of animal testing (Feb 17, 2021)

  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.
