Buying a micropipette can be a daunting task. With so many different types and brands on the market, how do you know which one is right for you? Check the size of the micropipette: When you are looking to buy a micropipette, you will need to check the size. You will want to find the size that is most appropriate for your needs. If you are looking for a micropipette that is used for general purposes, you will want to find one that is in the range of 0.5-10 microliters. If you are looking for one that is used for more specific purposes, you may need to find one that is smaller or larger.

How To Use A Micropipette

Micropipettes are a commonly used in laboratories to aspire and dispense liquid, usually down to 0.1 uL. They’re an essential part of the laboratory and if you work in a lab its very likely that you’ll have to use one. Whether you’ve never used one or you’ve utilized one for years, its always good to to refine your skills. Not only is a micropipette a crucial part of the lab, it is also an expensive one. Be sure to take care of it and have it calibrated at least once a year. Using a pipette past its volume limit will give you inaccurate results and possibly damage the pipette. It’s not worth pushing the micropipette past its limits to save time. Switch to an appropriate pipette that will allow you to work with the volumes you desire.


Micropipette and the Metric System

Work with DNA and enzymes frequently involves measuring very small volumes, often in the microliter range. The liter is the metric volume standard, and one microliter (μl) is one millionth of a liter. To make these precise measurements, the molecular biologist uses a micropipette. Work with DNA and enzymes frequently involve measuring very small volumes, often in the microliter range. A microliter (μl) is one millionth of a liter. Liquid measurements in the metric system are made in units based on the liter where a liter is about one quart. To make these precise measurements, molecular biologists use a precision tool known as a micropipette. This tool is as basic to their lab work as a hammer is to a carpenter. Micropipettes come in many models and sizes. In this lab, you will learn to use micropipettes accurately and to measure volumes using metric units including microliters. Mastery of this technique is essential for good results in the activities to follow.

Mastering the micropipette

Therefore, in every experiment, you will be required to accurately measure volumes as small as a few microliters (μL). Micropipetteswill allow you to do this accurately and precisely. 2.1: Using micropipettes correctly. 2.2: Using the spectrophotometer to evaluate your pipetting skills. 2.3: Light spectroscopy. Fill stroke Depress the plunger to the first stop Insert the pipette a few millimeters into the solution to be transferred Slowly release the plunger up to the starting position (tip will fill with fluid) For the most accurate transfers, keep the micropipette within 20 degrees of the vertical axis

Micropipettes Components, Types, Applications, Techniques

Based on the Operating Mechanism, micropipettes can be classified in two types; 1. Mechanical Micropipette The micropipettes are operated by hand using a spring piston mechanism. 2. Electronic Micropipette The electronic micropipette is usually automated. This includes the plunger, digital display and tip cone, as well as the tip ejector, and the grippy. Certain micropipettes come with a calibration tool as well as the stand for micropipettes as an option. Accurate measurement of liquids is dependent on the proper micropipette use. Air displacement micropipettes operate using the principle of air displacement. The plunger is compressed by the thumb, and when it releases the liquid is drawn towards the tip of a disposable. If the plunger is then pressed again and the liquid is dispersed.


FAQ Of Micropipette

What are the different sizes of micropipettes?

We use three different sizes of micropipettes in the laboratory, the P20, P200 and P1000. Our micropipettes have been purchased from several different manufacturers, but the principles of operation are the same.

What is a P20 micropipette?

Pipetmen come in three sizes which are capable of pipetting three. ranges of volumes: P20 = 0.5- 20 µl, P200 = 20-200 µl, and P1000 = 200-1000 µl. They are used. in conjunction with disposable (often sterile) plastic tips.

Which micropipette is used for 1 mL?

P1000: Maximum volume 1000 µl (= 1 ml). Accurate between 200 µl and 1000 µl. Numbers on the micropipette (typically red-black-black) are read X.


What volumes do micropipettes measure?

A micropipette can come in one of many standard sizes, and the most common can measure out a volume between 0.1 microliters and 1000 microliters. This is 0.0001 milliliters to 1 milliliter. Just as 1000 milliliters is equal to 1 liter, 1000 microliters is equal to 1 milliliter.

What are the two general types of micropipettes?

Micropipettes can be mainly categorized into two types – Air Displacement Micropipettes and Positive Displacement Micropipettes.
