(These are for Class A pipettes; Class B pipettes are given a tolerance of twice that for the corresponding Class A.) A specialized example of a volumetric pipette is the microfluid pipette (capable of dispensing as little as 10 μL) designed with a circulating liquid tip that generates a self-confining volume in front of its outlet channels.

Different sizes of rubber bulb, flip style pipette filler and wheel style pipette filler. The rubber bulbs can also be replaced with wheel style pipette filler or flip style pipette filler. The flip style pipette fillers have two valves system and have a removable top valve which makes cleaning easy and it can be used with one hand. [3] The ...
A pipette (sometimes spelled as pipet) is a type of laboratory tool commonly used in chemistry and biology to transport a measured volume of liquid, often as a media dispenser. Pipettes come in several designs for various purposes with differing levels of accuracy and precision , from single piece glass pipettes to more complex adjustable or ...
A Serological pipette is designed for use as a blow-out pipette. A Serological pipette also has graduation marks, which start nearer the end of the tip. The pipette can be blown out by gravitational force or air pressure. Rubber bulbs attached to the end opposite the tip are commonly used to "blow out" any remaining solution.
Plastic Pasteur pipettes. An eye dropper, also called Pasteur pipette or simply dropper, is a device used to transfer small quantities of liquids. [1] They are used in the laboratory and also to dispense small amounts of liquid medicines. A very common use was to dispense eye drops into the eye.
used for preparation of culture media and the culture of organisms they are in Glass beaker: reagent storage Glass flask: gastric acid, or other fluid titration: Pasteur pipette: for aspiration and addition of reagents Graduated pipettes: for aspiration and addition of reagents, often of minuscule amounts of the material; used mainly in ...
[2] [3] They thus are used for smaller-scale transfers than equipment such as graduated pipettes, which come in 5, 10, 25 and 50 mL volumes. The most common type of pipettes can be set to a certain volume within its operational range and are called adjustable. These pipettes commonly have a label with their volume range like "10–100 μL".
A Mohr pipette, also known as a graduated pipette, is a type of pipette used to measure the volume of the liquid dispensed, although not as accurately as a volumetric pipette. [1] These use a series of marked lines (as on a graduated cylinder) to indicate the different volumes. [2] They come in a variety of sizes, and are used much like a ...
