Takasago’s original designs
As a leading manufacturer for fluidic handling, Takasago, has been solving the troubles faced by design engineers in various ways, especially in analytical instruments where our experienced technologies are mainly adopted. In our long history of customization, we have come to set the original designs for high demand customizations as standard options for customers to select freely. Please refer to the following.
Takasago’s original designs
Reduces the residual volume of the valve chamber to the utmost limit.
Makes the pumping volume 100 times lower than our standard valves.
Better ability against sealing problems caused by infusion of foreign matter.
Promotes the ventilation of a valve, and heat radiation.
Enables you to monitor the movement of the plunger of a valve.
Does not require power to maintain valve state due to the incorporation of a permanent magnet into the actuator.
Install valves compactly and minimize the flow channels.
