Differential Digital Holographic Microscopy (DDHM)

Differential Digital Holographic Microscopy (DDHM) is a new quantitative imaging technique that allows cell counting as well as cell viability monitoring in a continuous, label-free set-up.

With this technique there is need for sampling (eliminating the risk of contamination) or staining and results are available in nearly real-time and this over the whole run. In the newly developed microscope a HaydonKerk linear actuator is used to pump the liquid through the system. This allowed perfect flow control, automated flushing (in case air bubbles or large aggregates are detected) and high reliability in a very compact design.

It is only one of many examples where Haydonkerk solutions are used in medical devices. More information can be found in the labautomation brochure.
