1. When was the electronic pipette invented?
Electronic Pipettes are handheld instruments commonly used in academic, biotech, pharmaceutical and other labs to transfer precise amounts of liquid from one container to another. Pipettes range from very basic graduated glass tubes to sophisticated precision instruments capable of aspirating and dispensing liquid in increments as small as a fraction of a microliter. The most common pipette used in life science labs around the world is the single-channel air displacement pipette.
