Non-metallic precision fluid transfer devices |
摘要 |
A device for delivering precisely measured, minute quantities of liquid has no metal parts which contact the liquid. The device employs a barrel defining member with a bore which receives a polymer coated glass or ceramic fiber which functions as a piston. Fluid is drawn into and discharged from the bore via a needle in the form of a polymer coated glass or ceramic capillary tube.
