SUGANORDNING FOR PIPETTER

摘要

The aspirator body includes a resilient cylinder with a piston reciprocable therein for aspirating a liquid into a pipette. The piston mounted on a pin concentrically held be a hollow plunger. The resilient cylinder and the hollow plunger reciprocates in an annular chamber formed by the body. An extension of the hollow body surrounds the pipette tube when it is held in fluid communication with the body and includes a magnifying lens to facilitate reading of the position of the body and liquid contained therein.
