Bürkert Fluid Control Systems has recently launched its latest addition to the micro fluidics range, the Type 6712 WhisperValve, which is a plunger type design with media separation, that measures only 7mm wide and has a switching time of less than 5 milliseconds. Designed for medical applications such as dialysis, drug delivery systems and in-vitro diagnostic work as well as precision inkjet printing, this latest development from Bürkert also has a very low switch noise of less than 36 dB, a mere whisper.
