A practical guide to selecting an electronic pipette
You only need to glance around any lab to be amazed by the sheer variety of instruments they employ—both in terms of quantity and size. These pieces of equipment can be big, taking up roughly half the space in the room, or small, taking up only a benchtop or even less. The electronic pipette is a piece of compact but crucial equipment that is common on various lab counters.
It
is safe to state that without it, a lab is lacking. The challenge one has is how
to select an electronic pipette while handling a particular activity because a
pipette can be employed for a variety of purposes. You can follow our easy,
step-by-step instructions for this. Writing down the specifics of the pipette
experiment you plan to do is a preparatory step. The number of samples, the
volume being transferred, replicates, the need for sterile conditions, and
other factors should all be included.
Creating
a precise list of the steps in this way will facilitate selecting the appropriate
pipette.
Step
1 - Selecting the type of pipette
Air
displacement micropipettes and positive displacement micropipettes are the two
primary categories of micropipettes. By comparing their applicability to the
experiment, you want to conduct; you can pick the best one.
Positive
displacement pipettes are utilized for radioactive, corrosive, dense, and
viscous substances as well as applications like PCR and DNA amplification
procedures. Air displacement pipettes are best for aqueous samples or
applications involving ordinary pipetting.
Step
2 – More factors for selecting your pipette
·
Fixed or variable volume
pipette
After
selecting the suitable type, consider the subtypes available depending on
parameters such as the volume to be handled, tip quality, manual or electronic
pipettes, and so on. This is when the experiment's finer details will come in
handy.
You
can either use a pipette with a fixed volume or one whose volume can be
modified as needed.If you frequently utilize a single volume, such as 100ul, in
your studies, choose a fixed-volume pipette. If your experiment requires
you to work with a variety of volumes, select a variable or adjustable pipette.
·
The Volume to be handled
As
a general rule, choose the smallest pipette capable of handling the required
volume because when the set volume is close to the micropipette's minimum
capacity, the accuracy and precision of the readings drop.
·
Single or Multichannel
Pipette
This
decision can be influenced by the number of samples or replicates used. When the
number of samples is small, single-channelelectronic pipettes however
multichannel micropipettes can easily manage large numbers of samples or well
plates (8-channel and 12-channel).
·
Pipette tips
This
is the most important decision to make after you've chosen your pipette.
Conical or cylindrical tips, universal or pipette specific, filtered or
non-filtering, and graded are all options.
If
the experiment calls for sterile, aseptic circumstances, utilize filtered and
sterile tips. Universal tips can be used with a variety of pipettes.
The
above factors can easily change your mind while selecting an electronic
pipette.
