How I do I choose a pipette?
To achieve the highest level of accuracy, you should choose the smallest volume pipette capable of handling the volume in question. This is important because pipette is most accurate at nominal (maximum) volume. It is a well-recognized fact that even slight muscle fatigue reduces the output when performing work that requires precision. Therefore, in order to maintain the performance, pipettes which require high forces should be avoided. Moreover, heavy pipettes fatigue the user, selecting an ergonomic pipette allows precise operation. Electronic pipettes can be considered when number of samples is high or when reducing variance in pipetting is important. A multichannel pipette can significantly speed up working with 96 and 384 well plates.
Which type of pipette is most accurate?
There is two principles of how pipettes work, air displacement and positive displacement. The majority of pipettes used in laboratories work according to air displacement principle due to their wide applicability and lower costs of consumables. Positive displacement pipettes are sometimes used with problematic liquids, but air displacement pipettes can be used as well with correct techniques. An electronic pipette can eliminate a lot of the variance from pipetting and also variance between users. With an electronic pipette the piston movement is controlled automatically regardless of the user.
What are the best pipettes?
Different pipettes can fit different application, for example when working only with few samples a mechanical pipette is good choice, but when working with 96 microwell plates multichannel pipette is a better option. But in general lighter pipettes are better ergonomically, electronic pipettes can reduce the variance, and using tips and pipettes from the same manufacturer creates the most accurate system. Remember that choosing the right tip is as important as choosing the right pipette!
What makes a pipette accurate?
Pipette will be accurate when you use correct pipetting technique considering liquid properties, use proper fitting tips, and keep it well maintained and calibrated.
What is the difference between pipette and burette?
Pipettes transfer liquid using piston system whereas burettes are graduated glass tubes. Pipettes are used when moving known amount of liquid and burettes are often used to determine unknown amounts.
