For over 50 several years, we’ve been making pipettes with accuracy, consolation, and reliability as a best priority. these days, we offer many different pipettes in A selection of ergonomic styles and volume measurements that boost your pipetting experience and assist you achieve reproducible, reputable success.
A pipettor, also referred to as a pipette controller or electronic pipette, is a motorized unit useful for specific liquid handling.
problems occur with foamy or viscous alternatives, the place foaming may result in inconsistent volume measurements and significant-viscosity liquids may perhaps necessitate additional power for correct aspiration and dispensing.
Volumetric Pipette: this is the sort of glass pipette which includes only one marking or graduation. It has a bulb in the center, although a similar sort Ostwald-Folin pipette has the bulb near its tip.
