A Short Guide on Pipettes
So Many Choices
There are so many options when it comes to choosing a pipette,
but we are here to clear up your doubts.
Manual pipettes can undoubtedly be considered the holy grail of laboratory work. They offer precision and durability at reasonable prices while most are fully autoclavable and easy to clean. If you are looking for a more modern approach, electronic pipettes are the right choice for you. Superior ergonomics and increased reliability will save you precious time when lots of repetitive pipetting is required.
Multi-channel pipettes are essential for high-throughput applications, PCR, ELISA and cell culture techniques, as they permit easy transfer of liquid within multiple channels (x8, x12, or x16). There are also some models that come with adjustable tip spacing in order to fit any plate format or application, and they can be manual or electronic, the latter providing you with the highest degree of efficiency.
Positive displacement pipettes provide leak-free and precise handling of viscous, volatile or dangerous liquids. This technology is often used in repeating pipettes, which allow direct distribution of liquids from a dispenser tip.
While you should always refer to the user’s manual for your pipette, there are some measures you should keep in mind so that your products last as long as possible.
In order to provide maximum accuracy and precision, keep your pipettes clean inside and out. Avoid liquids touching anything but the tip and be especially careful not to tilt the pipette horizontally when using it, so as to avoid soaking the piston. Always store pipettes vertically and in the appropriate rack.
Regular cleaning and calibration are essential, and different products require different care. For this reason, some brands offer maintenance and calibration assistance. Check out your trusted brand’s website for more information and to confirm that the service is available in your country.
