A pipette, also known as a chemical dropper, is used for transferring a measured proportion of liquid. This device is utilized in analytical chemistry, molecular biology as well as for carrying multiple medical examinations. This device is obtainable in various forms, shapes and sizes which are used with varying levels of precision and accuracy. In order to carry out all kinds of clinical examinations with high precision and to obtain error free results, these devices are used in all clinical laboratories.
Pipetteis available in multiple forms and is used for carrying multiple operations. From single piece glazed units to more intricate electronic and adjustable designs, these units are obtainable in various forms. Although the basic functioning of every form of pipette is same but depending upon accuracy of result required, most advance devices are used. A partial vacuum is created by these devices above the chamber which is used to hold the liquid and then appropriate amount of vacuum is released in order to draw the liquid above. Same methodology is used by all pipettes for dispensing multiple forms of liquids. While simplified pipettes are used for testing less vital liquids, the more advanced versions are employed for carrying testing of liquids that require highest precision in results.
There are two types of pipettes available depending on the volume of liquid being dispensed by them. The one which dispenses 1 and 1000 ul amount of liquid is called as micropipettes while other used for dispensing volume more than this amount is known as macro-pipettes. Based on these two types, there are two other forms of pipette - positive displacement units and air displacement units. Normally, pipettes which are air based are used for carrying functionalities of micropipettes while latter is used for testing liquids with high volume. The amount of liquid which is to be displaced through this unit is set with help of a readable meter available on these units.
There are multiple forms of these units available which can be selected by individuals depending upon volume of liquid to be tested. Adjustable, fixed, single-channel, repeater, multi-channel, volume handled, locking, electronic, manufacturer, standard are some of the forms of this pipette which can be obtained by individuals. In addition to this, there are graduated pipette, Pasteur pipette and volumetric pipette as well those which are easily obtainable for carrying on high precision examinations. The best fact about these entire multiple forms available is that even if individuals are using it for the first time, they can use it without any hassle.
A pipette is available with various forms of accessories which are used for carrying on the complete testing process. These accessories are fillers, dispensers, pipette tips and pipetting systems. Each of these accessories possesses a unique functionality and is therefore used in testing procedure, if required. Zeptoliter pipette is the smallest form of pipette available which is made of carbon shell along with a gold alloy. Pipette is the most important device without which any examination is not possible and for this reason only qualitative pipettes must be selected by individuals.
