It is very evident from all the research and development taking place today all over the globe in terms of vaccination development and finding a permanent cure for the situation COVID has put everyone in and this credit most certainly goes to all the scientists and lab experts working overtime in their labs and displaying their expertise. These labs have to certainly have the best equipment the industry has to offer, right from huge testing instruments to pipets. One such significant component every lab has are serological pipets.

 An individual may not understand what serological pipets are, but not to worry as, unlike every other complex guest post and articles, this article is to help understand the definition and types of the pipets along with their uses.

Serological pipets are a very important part of lab equipment where it is a long tube that is used to transfer the liquids from one container to another and this measurement lies between 1 millilitre to around 50 millilitres. These pipets are made of either glass or plastic, to cater to all budgets, as the glass pipets are slightly expensive.

Uses of the Serological pipets:

  • The primary use of this pipets is to enable the mixing of two or more components in a beaker for testing. These components will be introduced with precision as only a specific quantity of them will be needed, which is made easy with the help of the pipets.
  • Some chemical solutions and reagents need mixing in a way that things do not get contaminated with one another even by mistake and hence this pipets helps introduce the reagents with precision.
  • Next noteworthy use of this pipets is to transfer cells that are being studied under the microscope for either analysis purpose or expansion purpose. This pipets will help transport the analysis specimen from the container to the glass dish carefully.
  • Another especially interesting use of this pipets is to create a gradient of higher density which is performed by layering the reagent on top of one another as per the chemistry.

The various types:

These pipets may have variants but three main types are considered the best way of their bifurcation. The three main variants are Open-ended, Aspirating and Bacteriological.

  • Aspirating pipets: These pipets in contrast to the others have absolutely no graduations to indicate the volume of liquid taken into the pipets. This particular type of pipette is used specifically to transfer a mixture liquid from one point to the next for example in processes like pipette aspiration or even vacuum related processes. These pipes, using gamma rays are sterilized before each use to reduce error.
  • Open-ended pipets: This specific kind of pipets comes with an end that is open which leads to the exposure of the liquid with the atmosphere and this pipets is extremely useful to measure the liquids with a higher viscosity. One speciality of this pipets that makes it ideal for working with fluid elements like paint, oil, sludge or even liquid cosmetics is that it allows for a fast-fill and fast release flow rate of the viscous fluid. This pipets has an additional feature that enables the prevention of liquid contamination, and this is a fibre filter, and these pipets are sterilized before each use, using gamma radiation.
  • Bacteriological pipets: This pipets mostly used to study and transfer liquids like dairy products such as milk. They are not only non-pyrogenic but also a one time use pipets that is sterilized by gamma radiation before its use. These pipets also have fibre filters that prevent fluid contamination during testing to avoid errors in the results.
