Single Channel Electronic Pipette Controller, 0.1ml-200ml

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 factors affect the accuracy of an electronic pipette?

• Temperature: The most important factor for pipetting accuracy is the temperature of the liquid. The graph below shows the change in volume when the temperature of the liquid is different from that of the pipette and air. If the temperature of the liquid, pipette and air are the same, accuracy will not be significantly affected.
• Density: Density is the mass/volume ratio of a liquid. Density varies with temperature and air pressure. Generally, the density of water is 0.996 kg/dm3, that of ethanol is 0.79 kg/dm3, and that of sulfuric acid (H2SO4) is 1.85 kg/dm3.
• Altitude: Geographical altitude affects accuracy through barometric pressure. At high altitudes the barometric pressure is reduced and the conversion factor Z is reduced. The boiling point of some liquids can also vary very close to room temperature, dramatically increasing evaporation losses.
