Q1: What is a pipette?
A1: A pipette (sometimes spelled as pipett) 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 instrument.
Q2: What pipette is used for?
A2: A pipette is a laboratory instrument used to measure out or transfer small quantities of liquid, in volumes of milliliters (mL), microliters (μL).
Q3: Why pipette is the most accurate?
A3: Although convenient and less time-consuming to use, graduated cylinders are considered to lack precision due to their large meniscus when compared to pipettes. The long, narrow, and slender neck of the volumetric pipette make it easier to measure and read the meniscus very precisely.
Tips: What are the advantages of a multichannel micropipette?
Multi-channel pipettes function in the same way as single-channel pipettes, but they utilise multiple tips for measuring and dispensing equal amounts of liquid at once. Common setups are 8 or 12 channels. Multichannel pipettes can increase productivity. The number of pipetting steps can be dramatically reduced again by using an electronic 8 or 12-channel pipette which has a multi-dispense, autopace function, bringing a level of automation to the bench top.
