Parts Of A Micropipette

Basic parts of a micropipette include plunger button, tip ejector button, volume adjustment dial, volume display, tip ejector, and shaft. They differ in design, weight, plunger force, and overall precision. Depending on your budget and preference, there are plenty of micropipettes in the market that specifically catered to meet your needs. Volume adjuster: At the top, there is a circle which is used to adjust the volume of the liquid as our wish. Plunger Button: Below that is Plunger, which is used to pick up and dispense the liquid in the micropipette. Tip Ejector Button: These is used to release the tip. Make sure we want to take new tip for each transfer. Display Volume Indicator: These shows the how much volume the liquid is transfer into the pipette. Disposal tip: These is used for only transfer purpose. which is at the bootom of the pipette.

What is a micropipette?

Micropipettes are utilized in the laboratory to transfer small quantities of liquid, usually down to 0.1 uL. They are most commonly used in chemistry, biology, forensic, pharmaceutical, and drug discovery labs, among others. A micropipette is a common yet an essential laboratory instrument used to accurately and precisely transfer volumes of liquid in the microliter range. Micropipettes are available in single channel and multi channel variants. Common micropipette sizes used in labs include: Common Micropipette Sizes Volume Range P2 0.2-2 uL P10 1-10 uL P20 2-20 uL. A Micropipette is a standard type of laboratory equipment that is used to measure the small volumes of liquids. Micropipettes are also used to transfer a small volume of liquids accurately from one vessel to another.


Micropipettes & Guidelines of Micropipetting

Check your pipette at the beginning of your working day for Dust & Dirt on the outside. If needed, wipe with the 70% Ethanol or Isopropyl alcohol. ⇒ Set the volume within the range specified for the pipette. Most of the pipette can be cleaned externally with typical laboratory cleaning agents, soaps or alcohol. To ensure the full sterilization, let the cleaning solution sit on the micropipette for 10-15 min before wiping it off. Micropipettes are used to measure and dispense small volumes of liquids (usually less than 1 milliliter). Different sizes of micropipettes are used depending upon the volume of the liquid measured. The most common micropipettors are the P20.

Anatomy of a Micropipette

The pipettes you have may not look exactly like this one, but all the basic parts are the same. Always be sure the pipette you’re using is appropriate for the volume you’re transferring, and never tilt the pipette when there’s liquid in the tip (it can flow into the pipette barrel). Using an 8-channel micropipette is essentially the same as using an individual pipette. The advantage of an 8-channel is that you can extract the of liquid from adjacent wells in a 96-well plate at the same time. The anatomy of the 8-channel is the same as an individual pipette, except that you have eight tips instead of one. When using a micropipette, it is critical to follow these safety measures:!Never attempt to pipet a volume outside of the specified volume range for each micropipette !Always use gloves when handling biological fluids, strong acids, strong bases, or toxic.

Introduction to Micropipetting

Introduction to Micropipetting: The ability to measure very small amounts, microliters (µl), of liquid chemicals or reagents is a fundamental skill needed in the biotechnology or research lab. Scientists use a device called a micropipette to measure these very small volumes with accuracy. This activity introduces the technique of micropipetting. The proper storage of micropipettes is just as crucial as cleaning and calibrating the devices. The micropipette as well as accessories must be kept in a cool, clean and dry area. The storage space should have temperatures ranging between -20°C and 50° degC (from -4 degF up to 120°F) with the relative humidity ranging between 5 and 95 percent.


FAQ Of Micropipette

What is the name of the part on a Micropipettor that is pressed down to expel the fluid?

Plunger (button at the top)- This is pressed down and released to draw liquid into the micropipette. It is pressed again to expel the liquid.

What is the difference between micropipette and Macropipette?

Pipettes that dispense between 1 and 1000µl are termed micropipettes, while macropipettes dispense a greater volume. Pipettes enable sterile and accurate liquid handling and are commonly used within molecular biology, analytical chemistry and medical tests.

What are the two general types of micropipettes differentiate the two?

Micropipettes are of two types, the Fixed micropipettes, and the Variable Micropipettes. The Fixed micropipettes are designed to transfer the fixed amount of volume of the liquid.

When aspirating using a Micropipettor if you push to the second stop you will get?

Most micropipettors have a two-position plunger with friction “stops”. Depressing to the first stop measures the desired volume. Depressing to the second stop introduces an additional volume of air to blow out any solution remaining in the tip.


Why do we need to learn how do you use micropipettes in the molecular laboratory?

Micropipettes (Figure 1) are used to transfer small amounts of liquid accurately from one container to another. Learning to properly use a micropipette is considered an essential lab skill and like any skill, takes practice.
