Pipet -- Make measuring more reliable and accurate
Many different applications have been performed in laboratories which demand precision liquid handling. In particular, pipet have come a long way because the most former varieties came into use. The earliest versions of the contemporary electronic multi-channel pipettes which are widely in use in labs and medical facilities have left a lot to be desired in terms of safety and precision.
In early days, the operator would make suction on one end of the instrument using his/her mouth. But, today we are a lot more careful about the possible dangers posed by biological samples. Pieptes of these days use the air displacement strategy for greater accuracy and moreover, they are now much safer to use.
