This is a ultra-small solenoid diaphragm valve with the outer diameter of 5.7 mm, which is highly chemically inert. The internal volume is only 1.2 μl (pipe type: 4.3μl).

The internal volume pursued miniaturization to the limit of 1.2μl. Among these, the internal volume of the valve chamber, which can be a dead volume, is only 0.75 μl. It can help to reduce the amount of samples and improve the accuracy.
