摘要

A Device For The Contactless Metering of Liquids A device for the non-contacting dosing or metering of liquids, designed as a dosing syringe, comprises a piston centrally disposed within a sleeve, with a spring surrounding the piston. The spring bears against an upper end of a barrel within which the piston reciprocates and which is surrounded by the lower and of the sleeve. The outside of the barrel is formed with stroke-limiting abutments.
