Universal pipette tips are specially designed tips that fit a wide variety of pipettes, making them highly versatile and convenient for laboratory use. They ensure accurate and consistent liquid handling, which is crucial for various tasks in biological research, clinical diagnostics, and other lab procedures where precise pipetting is important.
Do's: Use correct size pipette tips, dispense liquids slowly to avoid splashing, hold pipette vertically when aspirating and dispensing, calibrate pipettes regularly. Don'ts: Avoid dragging pipette tips across surfaces, never reuse disposable tips, do not over-pipette by pressing plunger too hard, do not blow out the remaining liquid in the tip.
Micropippettes with its tips are used to load DNA on the gel. This must be calibrated to pipette the accurate microlitres from the sample.
The instrument that holds the pipette is called a pipette bulb or a pipette filler. It is used to create suction for drawing liquid into the pipette and controlling its release.
Another name for Pasteur pipette is transfer pipette.
A Mohr pipette is a type of pipette that measures the volume of dispensed liquids. It is less accurate compared to a volumetric pipette.
Pipettes are used to move specific volumes of fluid between containers. For very small volumes, or very precise applications, a large error in the desired fluid volume can have a very large impact. Calibrating a pipette ensures that the volume desired is the volume collected. Proper sealing of pipette tips can also have a large impact on fluid volumes collected.
A 1 ml pipette, a 2 ml pipette, a 5 ml pipette, and a 0.5 ml pipette.
A TD pipette delivers a fixed volume of liquid, while a TC pipette can be adjusted to deliver different volumes.

To safely draw liquids into a pipette
The glass with measurements that is attached to a pipette is called a graduated cylinder.
A pipette filter is a tool used to fill pipettes, which are small and sometimes fragile, and thus difficult to fill without any tools. Pipette filters act as funnels that attach to the top of the pipette and have a mechanism to pour into it.
