What experiments are pipettes used for?
Calibrated serological pipettes can hold and deliver liquid volumes from 0.1 ml to 25 ml. They are typically used in laboratory activities such as Blood Banking, Urinalysis, Hematology, and Immunology. Pasteur pipettes are also known as eyedropper pipettes.
What is a pipette and how does it work?
Air Displacement Pipettes Liquid is pulled in and pushed out through the use of displaced air. Each of these pipettes has an internal piston connected to a plunger. For an air displacement pipette, the plunger directly pushes out a volume of air equal to the liquid that will be aspirated.
What is the measurement of a pipette?
Accordingly, pipettes vary in volume, with most measuring between 0 and 25.0 millilitres (0.00 and 0.88 imp fl oz; 0.00 and 0.85 US fl oz).
What is the difference between a pipette and a pipette?
Pipette and pipet describe completely different liquid handling devices—for example, pipette is used for the device that you use pipette tips with, whereas a pipet describes the glass (or plastic) tubes used for serology (serological pipet) and chemistry (volumetric pipet).

Why is a pipette more accurate?
The main advantage of a volumetric pipette is its accuracy. It is especially precise when it is delivering solutions, as another advantage of the standard build is its narrow neck. This allows for the meniscus to be read more accurately, and therefore deliver more precise results than graduated pipettes.
What are the types of pipettes used in the chemistry laboratory?
A Brief Guide of Pipette Types
- Volumetric Pipettes. In general, volumetric pipettes are used by those investigating chemical properties and analysing reactions.
- Graduated pipettes. Graduated pipettes are less accurate than volumetric pipettes.
- Vacuum-Assisted Pipettes.
- Micropipettes.
- Pasteur Pipettes.
What is the most common pipette?
Due to their versatility and wide volume range, variable volume air displacement single-channel pipettes are the most used laboratory instruments.
What are the uses of pipette in laboratory?
Types of Pipettes. Pipettes may be constructed out of glass or plastic and are used to transfer a measurable amount of liquid.
How to use lab pipettes?
Position the pipette over the receiving container. Remove the tip of your pipette from the liquid.
