A pipette sometimes spelled pipet is a laboratory tool commonly used in chemistry, biology and medicine 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 electronic pipettes. Many pipette types work by creating a partial vacuum above the liquid holding chamber and selectively releasing this vacuum to draw up and dispense liquid. Measurement accuracy varies greatly depending on the style. HistoryeditThe first simple pipettes were made in glass, such as Pasteur pipettes. Large pipettes continue to be made in glass others are made in squeezable plastic for situations where an exact volume is not required. The first micropipette was patented in 1. Dr Heinrich Schnitger Marburg, Germany. The founder of the company Eppendorf, Dr. Heinrich Netheler, inherited the rights and started the commercial production of micropipettes in 1. The adjustable micropipette is a Wisconsin invention developed through interactions among several people, primarily inventor Warren Gilson and Henry Lardy, a professor of biochemistry at the University of Wisconsin Madison. NomenclatureeditAlthough specific descriptive names exist for each type of pipette, in practice any type of pipette will merely be referred to as a pipette and the desired device will be obvious from context. Sometimes, pipettes that dispense between 1 and 1. Common pipetteseditAir displacement micropipettesedit. Single Channel Pipettes designed to handle 1 5ml and 1.

Air displacement micropipettes are a type of adjustable micropipette that deliver a measured volume of liquid depending on size, it could be between about 0. These pipettes require disposable tips that come in contact with the fluid. The four standard sizes of micropipettes correspond to four different disposable tip colors Pipette type.

A vacuum is generated by the vertical travel of a metal or ceramic piston within an airtight sleeve. As the piston moves upward, driven by the depression of the plunger, a vacuum is created in the space left vacant by the piston. The liquid around the tip moves into this vacuum along with the air in the tip and can then be transported and released as necessary. These pipettes are capable of being very precise and accurate. However, since they rely on air displacement, they are subject to inaccuracies caused by the changing environment, particularly temperature and user technique. For these reasons this equipment must be carefully maintained and calibrated, and users must be trained to exercise correct and consistent technique. The micropipette was invented and patented in 1. Dr. Heinrich Schnitger. Marburg, Germany. Afterwards, the co founder of the biotechnology company Eppendorf, Dr. Heinrich Netheler, inherited the rights and initiated the global and general use of micropipettes in labs. In 1. 97. 2, the adjustable micropipette was invented at the University of Wisconsin Madison by several people, primarily Warren Gilson and Henry Lardy. Micropipettes brands include Gilson, Ergo.

Irrespective of brand or expense of pipette, every micropipette manufacturer recommends checking the calibration at least every six months, if used regularly. Companies in the drug or food industries are required to calibrate their pipettes quarterly every three months. Schools which are conducting chemistry classes can have this process annually. Those studying forensics and research where a great deal of testing is commonplace will perform monthly calibrations. Positive displacement pipetteeditThese are similar to air displacement pipettes, but are less commonly used and are used to avoid contamination and for volatile or viscous substances at small volumes, such as DNA. The major difference is that the disposable tip is a microsyringe plastic, composed of a plunger which directly displaces the liquid. Positive displacement pipette. The chuck which will be used to move the plunger. An early pipette. Volumetric pipettesedit. Several sizes of volumetric pipette. Volumetric pipettes or bulb pipette allow the user to measure a volume of solution extremely precisely precision of four significant figures. These pipettes have a large bulb with a long narrow portion above with a single graduation mark as it is calibrated for a single volume like a volumetric flask. Typical volumes are 1. L. Volumetric pipettes are commonly used to make laboratory solutions from a base stock as well as prepare solutions for titration. Graduated pipetteseditGraduated pipettes are a type of macropipette consisting of a long tube with a series of graduations, as on a graduated cylinder or burette, to indicate different calibrated volumes. They also require a source of vacuum in the early days of chemistry and biology, the mouth was used. The safety regulations included the statement Never pipette by mouth KCN, NH3, strong acids, bases and mercury salts. Some pipettes were manufactured with two bubbles between the mouth piece and the solution level line, to protect the chemist from accidental swallowing of the solution. A person pipetting by mouth, now considered an unsafe practice. A manual propipetter adjusted by turning the wheel with the thumb. A manual propipetter adjusted by squeezing the bulb. An automatic propipetter adjusted by pressing the button and toggling the switch. An automatic propipetter adjusted by pulling and releasing the triggers. Pasteur pipetteedit. Pasteur pipettes with rubber bulbs attached. Pasteur pipettes are plastic or glass pipettes used to transfer small amounts of liquids, but are not graduated or calibrated for any particular volume. The bulb is separate from the pipette body. Pasteur pipettes are also called teat pipettes, droppers, eye droppers and chemical droppers. The proper handling of the pipettes is by holding the rubber bulb between the thumb and index finger and controlling the glass by holding it between the ring finger and the pinky. The middle finger is not used. Transfer pipetteseditTransfer pipettes, also known as Beral pipettes, are similar to Pasteur pipettes but are made from a single piece of plastic and their bulb can serve as the liquid holding chamber.
