The development of an electronic micropipette was made possible thanks to recent advances in micro-pipetting technology. A micropipette is an instrument used for delivering liquids in a laboratory setting. The micropipette releases the full volume of the liquid from the tip into a separate container. Its advanced features allow researchers to accurately measure the concentration of reagents and solutions. The advantages of an electronic micropipette are numerous.
Powered single-channel pipettes are commonly used in laboratory settings. They feature disposable pipette tips and are typically pre-programmed or programmable. There are two major types of powered pipettes: positive-displacement and repeating. The Picus is a good example of an electronic micropipette. This device offers a large display with programmable buttons, allowing users to select and store their desired parameters.
When cleaning an electronic micropipette, it is important to follow specific guidelines to avoid cross-contamination. Most micropipettes can be autoclaved, but if the micropipette is sensitive to liquids, the device should undergo a sterilization process. The manual will give you instructions for the optimal temperature, duration, and cleaning process. When using micropipettes, it is important to resuspend each reagent in a different pipette tip. Why is it recommend that you use a different pipette tip to resuspend each pellet? Because the first reagent in a pipette tip is the master mix or primer.
Manual pipettes can be ergonomic alternatives. They provide a consistent pipetting force, reducing human error. However, prolonged pipetting can cause repetitive strain injuries, and an electronic pipette eliminates this risk. An electronic pipette also offers a customizable program, allowing scientists to customize the device to suit their specific needs. There are many different types of micropipettes available on the market, such as single channel, multi channel, and 364-well.
Air displacement micropipettes work by dispense liquid by depressing a plunger. The tip is then placed on the inner wall of the pipette at a steep angle. The plunger is then released and the liquid is dispensed. However, residual liquid remains in the tip and does not belong to the dispensing volume. Its use is a crucial part of biomedical research.
The volume of liquid collected with an electronic micropipette varies by the size of the tips. Most types are adjustable, and have an adjustable volume range. The maximum volume range is indicated by a specific acronym on the micropipette's tip. Both mechanical and electronic micropipettes have a variety of sizing options. The latter is easy to use and can be programmed to follow a specific working protocol.
Ergonomic designs of electronic pipettes reduce the possibility of repetitive strain injury. The ergonomic shapes of some electronic pipettes have been redesigned for ease of use and reduced thumping activity. In addition, some electronic pipette models are lighter than their mechanical counterparts, which allows for increased comfort for users. Ultimately, an electronic micropipette will help laboratories reduce their risks for repetitive strain injuries.
When using an electronic micropipette, researchers should calibrate it regularly. Fixed pipettes should be calibrated once a year, while variable micropipettes should be calibrated every three to six months. Single channel pipettes should be calibrated monthly, though heavy chemicals can affect their accuracy. When in doubt, consult with your QA manager for guidelines on how often to calibrate your electronic micropipette. And remember to check your samples frequently to avoid contamination.
When the term adjustable micropipette first came about, many scientists were confused about how to use it. In reality, it is a hand tool that allows scientists to measure small amounts of liquid or air. The first adjustable pipette was made 30 years ago to measure traces of air, but over time, manufacturers began to develop new variations that would allow researchers to easily adjust the tip to fit their hands. In the process, the micropipette gained a reputation as an icon of molecular biology.
The pipettes themselves are made of premium grade PP and PA materials. They feature individual tests for accuracy and calibration stability. The volume range can be adjusted quickly and easily with the push of a button and the ejector is built into the device. The pipettes are easy to calibrate and feature a large digital volume display. Its design and ergonomics reduce repetitive strain injuries and ensure that they are comfortable to hold.
Micropipettes can be divided into two types: Fixed volume and adjustable volume. The former has a movable plunger that you can move from one end to the other. The latter allows you to adjust the volume within a given range. Generally, the accuracy of an adjustable micropipette is a few percent. But if you need to make adjustments in a smaller range, you should consult your manual to determine how to do so.
Adjustable micropipettes are also known as single channel variable volume pipettes. They come in a wide range of volumes, from 0.1 ul to 10,000 ul. Listed below are common models with variable volume. Each one is named according to the maximum volume it can aspirate and the permissible error limits. Single channel micropipettes are often referred to as P10, P1000, or P1000.
Another type of micropipette is called an air displacement pipette. This device is similar to an air displacement pipette, except it is designed to work with smaller volumes of DNA. The piston moves up and downward, displacing the liquid around the tip. This method requires very little force, but is subject to changing conditions and user technique. However, it is not without its disadvantages. The air displacement pipette is the most popular choice for most laboratory workers.
When using an adjustable micropipette in a laboratory, it is important to check the accuracy of the tips regularly. After setting the correct volume for your experiment, pipette the sample five times. After each dispense, measure the volume with an electronic balance. If the dispensed liquid volume is incorrect, calibrate the micropipette as needed. If it is not, you should repeat the experiment every three months or once a year.
