Your Quick Guide to Using a Pipettor

One of the most important tools found in many laboratories is the pipettor. Pipettors are used to carry and dispense measured volumes of liquid. They hold a certain amount of liquid and dispense it by releasing the vacuum based on the user’s preferred volume. Several industries rely on pipettors for several of their activities.

In addition to medical and clinical facilities, pipettors are also commonly used in food and beverage firms. Furthermore, they are also considered a staple in chemical and pharmaceutical laboratories. In essence, pipettors are designed to facilitate the accurate moving of liquid from one container to another.

Using a Pipettor: Your Easy Guide

Below is a quick insight on how to use a pipettor correctly:

  • You need to attach a tip to the device before you press the button to the first stop. This enables you to position it properly so it can effectively draw liquid without spilling it.
  • You need to dip the pipettor’s tip (ideally 2-3 mm) prior to releasing the button. Going below 2-3 mm can minimize the amount of fluid drawn and might displace the liquid.
  • Slowly take the tip off. Doing it in haste might result in spillage and contamination.
  • In liquid transfers, the tip must touch the vessel’s wall. This can help ensure the liquid won’t spurt out during accidents or mishandling.
  • The button should be held in the second position while removing the tip that’s touching the wall of the vessel. The button is then released to also release the liquid. It is also important to make sure all the liquids have been effectively released into the vessel before facilitating another transfer.

The Benefits of Using a Pipettor

Pipettors can make drawing of liquid samples easy.

Without pipettors, drawing liquid samples can be difficult. Ensuring that the volume is precise is not always a one-step procedure. This is also often the case if the procedure is done manually. Fortunately, with a pipettor, it’s easier to control the liquid that is dispensed and spilling and inaccurate transfers are avoided.

Pipettors can help prevent contamination.

Since only certain parts of the pipettors are handled by the user, contamination is easily prevented. Since the liquid is directly drawn from the source, the risk of contamination is also smaller. During handling, liquids are also kept at semi-vacuum to ensure it is not exposed to contaminants.
