Product Information

Quality Control: In manufacturing processes, pipettes are used for quality control purposes, such as ensuring that products are made to specific standards. Alternatively, a consultation visit from one of our highly experienced product specialists is available for this range. Typically our specialist will be able to go through the following aspects with you to help you make the right choices and be able to deliver them on time and and on budget. Budget will often play a role in the type of pipettes used in laboratories. Electronic pipettes are generally more expensive than their manual counterparts, which makes them more common in less technical laboratories. 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.

A special pipette used in measuring viscous fluid such as whole blood. Common in medical technology laboratory setups together with other pipettes. Invented by Friedrich Wilhelm Ostwald, a Baltic German Chemist and later refined by Otto Folin, an American chemist. [7] [ failed verification] Winkler–Dennis gas combustion pipette [ edit ] As they are used routinely in clinical, industrial, research and analysis laboratories, a key factor with any liquid handling device is ergonomics. SciPette products are specifically designed to reduce RSI (repetitive strain injury) and decrease physical stress, so they are light weight but also of high quality. Many items in the range have a 3-year warranty included, so you can be sure our liquid handling and pipettor range is a wise choice. We also offer other pipettor accessories, including pipettor stands, pipette pumps, pipettor tips and more. Pre-wet the pipette tip by aspirating and dispensing the nominal volume 3 times to humidify the air cushion. Proper pipetting posture is the most important element in establishing good ergonomic work practices. [16] During repetitive tasks such as pipetting, maintaining body positions that provide a maximum of strength with the least amount of muscular stress is important to minimize the risk of injury. A number of common pipetting techniques have been identified as potentially hazardous due to biomechanical stress factors. Recommendations for corrective pipetting actions, made by various US governmental agencies and ergonomics experts, are presented below. 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.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: The small and compact nature of single-channel pipettes means they’re ideal for use with small source and destination vessels, such as conical tubes and flip-cap containers. As well as being compact enough for use with small vessels, single-channel pipettes work well with troughs and well plates. P10– These tips are transparent (white). They have a volumetric range between 0.5 to 10 microlitres.

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. https://www.pipettes.com/calibration-services/pipettes-university/accuracy-matters-blog/how-to-use-various-types-of-pipettes 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 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 instrument. Although specific names exist for each type of pipette, in practice, any type can be referred to as a "pipette". [3] Pipettes that dispense less than 1000 μl are sometimes distinguished as micropipettes. This section needs additional citations for verification.

The micropipette was invented and patented in 1960 by Dr. Heinrich Schnitger in 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 1972, the adjustable micropipette was invented at the University of Wisconsin-Madison by several people, primarily Warren Gilson and Henry Lardy. [5]Is the task repetitive? If so, ergonomically designed pipettes can be beneficial as they reduce fatigue and minimise the risk of errors that can jeopardise accuracy and precision.
