PIPETTE SERIES COMPARISON BY PRODUCT FEATURE

Surprisingly, the purchase of an automatic pipette is not a simple task. When you make the choice you should consider both parameters, as well as the skills of the pipette user. For example, in research, where precision is particularly important, it is the 4-digit counter and volume lock that would really matter. But for people who are just learning to work with a pipette it would be important to use a pipette with perceptible pipetting stops to minimize the risk of error. The following table compares the features of all the variable volume pipettes currently offered by HTL:
