Abstract:
A manual pipette having a cushioned hand grip area and a tip ejector. The ejector is located strategically so that an operator can easily manipulate either the ejector or a pipette fluid plunger which introduces and expels fluid to be sampled. The pipette is ergonomically balanced and designed to prevent operator fatigue. The pipette includes structure for in field calibration and volume variation.
