Takasago Zero Internal Volume Option
Prevents Cross-Contamination, Reduces Sample And Reagent Volumes
The internal volume is the space between the isolation diaphragm and the valve body. When the valves close, this volume is trapped, often reducing the sensitivity of the instrument. In a conventional valve seat design, the protruding valve seat is hard and prevents the Teflon diaphragm from flattening against the valve body.
In the zero internal volume system, a special soft inert elastomer (perfluoroelastomer) is used for the valve seat. When the valve closes the soft protrusion presses flat, eliminating the internal volume.
