We are attempting our best to make This website person-helpful and resourceful with timely/current specifics of Each and every pathogen, illness because of them, pathogenesis, and laboratory prognosis.
A repeater pipette is a modified micropipette with the opportunity to dispense equivalent volumes of liquid repeatedly with no need to aspirate frequently. It will save the operator effort and time.
On this website publish, We'll introduce you to definitely several of the commonest types of pipettes and how to rely on them properly. We may also give you some tips on how to keep up and calibrate your pipettes to make certain their best efficiency and longevity.
