A volumetric pipette, bulb pipette, or belly pipette [1] allows extremely accurate measurement (to four significant figures) of the volume of a solution. [2] It is calibrated to deliver accurately a fixed volume of liquid. These pipettes have a large bulb with a long narrow portion above with a single graduation mark as it is calibrated for a ...
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 ...
The delivery time is described as the duration of time that the meniscus reaches the end of the tip starting from the topmost volume, which is specified as 5 seconds for Class AS bulb and graduated-pipette volumetric equipment. [4] TD/EX pipettes are the most common type. [8] Another type is identified as TC ("to contain"), or IN, which means ...
A 100 ml volumetric flask with stopper Volumetric flasks of various sizes. A volumetric flask (measuring flask or graduated flask) is a piece of laboratory apparatus, a type of laboratory flask, calibrated to contain a precise volume at a certain temperature. Volumetric flasks are used for precise dilutions and preparation of standard solutions ...
