What is a pipet and its types?

Pipet are used to transfer liquid from one container to another.


A pipet is a thin tube for suction small amounts of liquid which measures liquid volume and It’s a measuring tool made up of a glass tube used to accurately measure liquid volumes by drawing it into the tube. 

Understanding of pipets:

In chemistry, biology, and medicine, a pipet is used to transmit a measured volume of liquid. Pipet, meaning a little pipe in French. It is a tiny tube with an expansion that transfers liquids. 

 Pipets are of different sizes, shapes and designs. Heinrich Schnitger invented pipets in 1957. Simple glass pipets and complex adjustable pipets come in many designs and levels of accuracy.

 Many pipets pull up liquid by producing a partial vacuum above the liquid chamber and selectively releasing it. 

Types of pipet:

Volumetric pipets:

Volumetric pipets are for those who study chemical reactions and characteristics. You can find it easily in most schools, colleges, and expert labs. They are very accurate and can measure up to four major figures. They come in different sizes, which lets experts find out how much of a concentrated solution is in them. 


Micropipettes are likely in labs to move very small amounts of liquid which are less  0.1 uL. Besides, we can find it in labs for chemistry, biology, forensics, pharmaceuticals, and drug development. 

Pasteur Pipets:

Pasteur Pipets are of glass and with its bulb-shaped top, a Pasteur pipet looks like a regular dropper for liquids and also pasteur pipets are unreliable because They are mostly used in biology labs instead of chemistry labs to move watery liquids in one container to another. People often throw away Pasteur pipettes after using them.

 Serological pipets:

Many labs use the serological pipet to transfer milliliters of liquid from 1 to 50 ml. Glass or plastic pipets can be sterilized. Both types of pipets aspirate and dispense liquids using pipet aids and Pipets of various sizes can be utilize with the same pipet aid for multiple experiments. Serological pipettes can mix chemical solutions or cell suspensions, transfer liquids, or layer reagents of varying densities and these pipets can transfer exact milliliter amounts of lab solutions if the fluid is carefully distribute everywhere.

Pipetting Aids 

Pipetting Aids are use with one-time-use pipettes also These tools include simple rubber bulbs and electronic controllers that make some pipetting tasks easier and must be doing in repeatly. 

Pipets with slopes

The accuracy of graduated pipets is lower than that of volumetric pipets. Some call Mohr graduate pipets “drain-out pipets” because they have a zero at the beginning of the cone-shape end.

Transfer pipets:

Transfer pipet, also called droppers, are simple tools for moving liquids from one place to another and they are usually made of plastic and are meant to be thrown away in one use. They don’t have graduations like another pipet because they focus on qualitative rather than numeric liquid transfers. 

Pipets bulbs:

Pipet bulbs come with rubber bulbs on top while creating a reservoir that draws liquids into the pipet. These are call pipet bulbs. Pipet bulbs often use with graded and volumetric pipet that don’t have built-in ways to take in liquid because Pipet bulbs are necessary for taking precise readings of liquids in the lab. 


Pipets are diverse tools use in laboratories for various liquid handling tasks. They come in different types, each tailored to specific applications, from accurately measuring precise volumes to qualitative transfers. Understanding the distinctions between pipette types is crucial for ensuring efficient and accurate laboratory work.
