Why use a measuring cylinder instead of a pipette?

It's common to use measuring cylinders for handling potentially harmful substances, but there are advantages to using a pipette instead. Unlike a measuring cylinder, a pipette will be more accurate with all of the sample, accounting for every drop of the substance being held within the tool.

What are the advantages of micropipettes?

Micropipettes are accurate and precise and can transfer measured volumes of microliters of volume.

Why are electronic pipettes more accurate?

Electronic pipettes are more precise and accurate because they use a motor to control piston movement, so you will always dispense exactly the volume programmed. Pipetting protocols – including volumes and speeds – can also be pre-programmed and saved so that they are executed in the same way every time.

What is the advantage of using displacement pipettes in experiments in cell and molecular biology?

Positive displacement pipettes offer reduced volatile solvent evaporation and prevent cross contamination, since there's no contact between liquid and pipette.

What are the advantages of measuring cylinder?

Measuring cylinders are designed more specifically for accurate measurements of liquids with a much smaller error than beakers. They have many more graduation marks and have close to 0.5-1% error, which can be precisely used to measure liquids ranging from 1ml- 1L.

Why is measuring cylinder accurate?

Why is a graduated cylinder more accurate than a beaker? ... The accuracy of a graduated cylinder is higher because the graduations on the cylinder make it easier to more precisely fill, pour, measure, and read the amount of liquid contained within.

What are micropipettes and how it is useful in microbiology?

Micropipette is a laboratory tool, commonly used in Quality control department (Microbiology, Virology, Chemical). ... The micropipette is used to transfer small amount of liquids. Many modern micropipettes have a digital display in the side of the barrel to indicate the volume amount set by the volume control.

Why are micropipettes used in molecular biology?

Molecular biology laboratories utilize micropipetting instruments (micropipettors) as tools to accurately transfer very small volumes (microliters) of liquid from one container to another. Skillful use of a micropipettor is a critical component of molecular biology laboratory procedures.

Why it is necessary to calibrate the Pasteur pipette?

Pipette calibration is necessary to prevent inaccuracies in order to attain better results, performance, and longevity of the pipette itself.

What are electronic pipettes used for?

Generally speaking, an electronic pipet should be used for all applications that border on automation. Mechanical pipetting is used most when you have a limited number of different samples, with fewer repetitive steps. Mechanical pipets can be used for transfer of liquids or dilutions, but not for dispensing.

Do electronic pipettes need to be calibrated?

In general, electronic pipettes are factory calibrated using an analytical balance and distilled water in accordance with the ISO standards. Therefore, a new electronic pipette does not usually need to be calibrated. However, all pipettes require calibration at regular intervals to remain accurate and precise.

What is the difference between automated and manual operated pipette?

Instead of a technician manually setting volumes on a pipette or keeping track of steps in a method, semi-automated liquid handlers automate those aspects of the work, only requiring the technician to move a hand probe from vessel to vessel.

What is the difference between air displacement and positive displacement pipettes?

Both pipette types have a piston that moves in a cylinder or capillary. In air displacement pipettes, a certain volume of air remains between the piston and the liquid. In positive displacement pipetting, the piston is in direct contact with the liquid.

What is the importance of pipetting experience in the lab?

Good pipetting practices and techniques are essential to not data accuracy, but also reduce fatigue and lessens the risk of repetitive stress injury.
