Microsyringe AGAT MSH-1N is designed to measure the volume of liquid sample when it is introduced into the pipette-evaporator of chromatograph. Microsyringe is a mechanical piston dosing device consisting of a glass cylinder with a counting device (linear scale), a steel piston (rod) with a button and a steel needle.
The principle of action is to create in the removable tip (needle) of the glass cylinder alternately vacuum or overpressure, when moving in the calibrated channel of the cylinder of the microsyringe by a metal piston, resulting in the tip is sucked into or drained from the dosed liquid. The microsyringe is made of chemically resistant materials.
The body has an indelible scale with an illuminating stripe and duplicate dots on the opposite side of the cylinder to eliminate the effect of parallax. The microsyringe has a removable needle, sealing system and a guide with a dose lock, which prevents bending of the piston and allows to reduce error when repeatedly injecting the same dose.
