Flow Cytometry is a play of lights and reflections. It can be used in many applications from routine immunology labwork to specialized research laboratories, where various cell membrane epitopes or nuclei variations are examined. Flow Cytometers since their development in the 1960's underwent a long way and became highly sophisticated devices.

Combining up to 5 different light sources (mostly lasers) with precise optics, sensitive fluidics and computerized electronics in one machine, Flow Cytometry is now one of the most challenging fields for any company dealing with Life Science laboratory instruments.

We have deployed flow cytometry systems in a number of laboratories in the Czech and Slovak Republics. Through many specially cutomized solutions we have obtained valuable experience and know-how in this field. Our technical support centre is available to all customers in any country as an alternative to calling Partec (acquired by Sysmex) support directly.

We started cooperation with Partec in 2003. From 2005 we have agreed to cooperate on the exclusive distributor basis for the Czech and Slovak Republic and on the non-exclusive basis for Central European region. In 2014 Partec was acquired by Sysmex. From 2015 our company has no distributor status for Partec product range.
