By choosing heads, valves and accessories according to your specific field of research interest, CERTUS FLEX enables you highly flexible optimization of your experimental design.
Our patented micro valves are available with different nozzle diameters and valve travel in order to optimally adjust to your experimental design. Thanks to the use of hard materials for the valve seat (sapphire) and the valve ball (ruby), unrivalled possibilities open up for your micro valve applications. The hard-sealing micro valves structure guarantees precise opening strokes of a few hundredths of a millimeter and repeat accuracies in the range of thousandths of a millimeter.
The short opening travel and the correct actuation allow the micro valve to be switched 4000 times per second long-term. The finely ground and optimally polished inner forms of the valve nozzle and valve seat provide the best possible flow properties before emergence. This results in an exact dispensing jet for contactless dispensing and optimal drop formation. Additional guide elements in and around the hard material components and the already mentioned advantages, if properly applied, make for a long micro valve life-time. By using these high – quality materials, high chemical and mechanical resistance and compatibility values are also achieved.
Furthermore, the micro valves can be provided with a filter and all valves can easily be autoclaved or cleaned with ultrasound. The table below gives an overview of valve types and their typical application helping you choosing your optimal valve types.
