Pipette Confidently with PipetteRite – Control the Immersion Depth, Steady Your Hand, and Improve Ergonomics". Micropipette: These are used to measure very small volumes of liquid, typically in the range of microliters or even nanoliters.

While compact and easy to use, single-channel pipettes can only be used to transfer one liquid sample at a time. This means they can be tedious and time consuming to use when multiple transfers are required.

For any radioactive contamination, wash the micropipette with a solution like Decon and then air dry. The very first thing you should do is make sure that you choose the right pipette for your experiment. As explained above, an adjustable volume air displacement pipette is most accurate when pipetting at its maximum capacity, so you should always choose the smallest pipette capable of handling the required volumes.

Designed with precision in mind, micropipettes allow scientists to accurately extract, transport and dispense liquids in the microlitre range. Micropipette capacity ranges from between 1 and 1000 microlitres. Macropipettes are designed for larger quantities and offer a capacity range of between 0.25–5 mL.

It is a handheld device that is attached to the top of the pipette, and can be used to control the amount of liquid being transferred. Pipette PumpA plastic pipette is a disposable pipette. You can not use it again and again just like a glass pipette. As they are used for the transfer of liquids that are infected so these pipettes are discarded after use to maintain biosafety protocols. Better precision and accuracy – as they are less operator-dependent. You can also save pipetting protocols to reduce manual errors and prevent operator-to-operator variability. For example, a scientist transferring a PCR master mix to a 96-well plate would benefit greatly from using an electronic pipette. Using a manual pipette would require 96 individual transfers which would result in significant ergonomic strain. In contrast, an electronic pipette can slash the number of transfers by 30% or more, depending on tip size and the volume of liquid being transferred. As well as saving time, the use of electronic pipettes minimises the risk of hand injury and fatigue. 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. [1] [2] Nomenclature [ edit ] The type of task being performed is directly linked to pipette function in laboratory. Does the task require accuracy and precision, or is speed more important? The answer will determine what type of pipette is used.

Pipetting viscous and volatile liquids with an adjustable volume air displacement pipette can be challenging but mastered with the right technique and pipette tip. Viscous liquids should be aspirated and dispensed slowly using reverse pipetting. Using this technique, a larger volume than needed is aspirated, which compensates for the retained liquid adhering to the inside of the tip. Low retention tips are the ideal option for viscous liquids, and for very high viscosity liquids, or those that tend to foam, wide bore tips are recommended. When you're repeat dispensing multiple aliquots, you should discard the first and last dispense of the series, as they have the largest associated volume errors. Also known as variable volume air displacement pipettes, single-channel pipettes are extremely versatile and can be used for a variety of applications. Most offer a wide volume range of between 0 to 2500 microlitres. Depending on the application, scientists can choose to use adjustable of fixed volume single-channel pipettes. Pipette recalibration [15] is an important consideration in laboratories using these devices. It is the act of determining the accuracy of a measuring device by comparison with NIST traceable reference standards. Pipette calibration is essential to ensure that the instrument is working according to expectations and as per the defined regimes or work protocols. Pipette calibration is considered to be a complex affair because it includes many elements of calibration procedure and several calibration protocol options as well as makes and models of pipettes to consider.Quality Control: In manufacturing processes, pipettes are used for quality control purposes, such as ensuring that products are made to specific standards. When using a laboratory pipette, it’s critical to choose the right instrument for the job. As explored above, pipette performance and functionality can vary significantly between models. Before selecting a pipette the following should always be considered: Klingenberg, M (2005). "When a common problem meets an ingenious mind". EMBO Rep. 6 (9): 797–800. doi: 10.1038/sj.embor.7400520. PMC 1369176. PMID 16138087. Great for use in microplate applications, multichannel pipettes are ideal for small scale applications and repetitive tasks. Most feature between 8 to 12 heads and allow scientists to transfer multiple liquid samples using a single device.
