Explains Peter Swanson, M.D. at Intertronics: “The P-Dot CT achieves accurate volumetric dispensing with separate internal fluid and actuator zones. This design enables extremely easy changing of the wetted parts such as nozzles and dispensing needles, as well as making it easy to clean all the fluid carrying components.”
The micro dispensing valve P-Dot CT is designed for contactless dispensing of high viscosity materials and features extremely short triggering intervals (< 1ms) so that it is possible to accurately apply the smallest amounts of material over distances from 2mm to 40mm. The volume of single shots can be set from 3 to 200 nl. Thus, depending on the material, dot sizes from a minimum of 350 μm to a maximum of 2000 μm can be achieved. The separation of the fluid path from the actuator components as well as a longer tappet ensures protection of the valve system and safe operation.
