What is the pipette?
and pipette is the type of chemical drifter used in laboratory experiments to measure and transport solid volume of chemicals. There are several pipette designs, but all work in the same way. The pipette is inserted into a container filled with liquid, where it creates a vacuum. Vacuum suction attracts the determined amount of liquid and releases it to another. The pipettes are made of either borosilicate, alinosilicate or quartz. Micropipettes are issued between 1 and 1,000 microlitres. They are often used in experiments with microinjections and measurements because they are extremely accurate.
Volume pipette, such as a volume flask, is used to measure and release one specific amount of liquid to add to another. There are several different sizes for measurement of a predetermined amount of liquid, with popular sizes are 10, 25 and 50 milliliters. Volume pipettes are most commonly used in titration experiments. Is marked with a series of graded lines to measure the amount of liquid before and afterI am publishing. It is not as accurate as a volume pipette, but serves its purpose. It is not calibrated to a specific volume. This type of pipette resembles a large droplet.
The accuracy of the pipette depends on several factors. The most important factor is the training and experience of an experiment. An experienced chemist can make mistakes that affect the measurement. Another factor is the type of liquid that is pipetted. Regular use of corrosive liquids can damage the pistons and pipette fields, resulting in inaccurate measurements.
In the Order to ensure the accuracy of the pipette, it must be regularly calibrated. The pipette can be calibrated relatively easily without being sent by a professional. Verify that it is properly exhausted before calibration.
run the calibration by setting the dial to the highest volume. Using deionized water, pipette the liquid into the flask on the analytical balance. Measure and record the matternosta. Perform the procedure five times.
repeat the process with the dial to the lowest and medium settings. Compare the measurement and look for irregularities. If systematic discrepancies are recorded, adjust the calibration wheel clockwise or counterclockwise as needed. If there are accidental discrepancies, chemical technology may require improvement.
