Laboratory #1 – Pipette and Micropipette Reagents/Supplies

Reagents/Supplies: Micropipettes (P10, P20, P200, P1000); Pipettes (1ml, 2ml, 5ml); Micropipette tips; Micro centrifuge tubes; Sharpe pen; 250ml Erlenmeyer flask; Water; Fine balance; Balance. The proper use and technique of using a pipette and a micropipette is essential in molecular biology. For this lab we will practice using a pipette by moving water from a flask to a culture tube. We will practice using a micropipette by moving water from a flask to a micro centrifuge tube.

Selecting the Right Pipette Tip | Thermo Fisher Scientific

Selecting the Right Pipette Tip Select the correct tip for ideal sample recovery There is a pipetting system for virtually every application and requirement. The type of experiment you are performing and the physical properties of the liquid will determine the correct pipette tip to use. Standard pipette tips are multipurpose and available in a choice of capacities. Most pipette tips can accommodate a range of liquid volumes, typically 0 to 20µL, 20 to 200µL, or 200 to 1000µL. Choose a pipette tip size based on the transfer capacity of the pipette with which it will be used and the amount of liquid being transferred.


Micropipettes Components, Types, Applications, Techniques

Micropipette tip is a standard but essential instrument in the laboratory utilized to precisely and accurately transfer volumes of liquid within small microliter volume. There are a few elements that are common to all micropipettes. This includes the plunger, digital display and tip cone, as well as the tip ejector, and the grippy. Based on the Working Principle Micropipettes can be classified into two categories: Air Displacement Micropipette; Positive Displacement Micropipette. They may be referred to as P10 or P20, P1000 or P5000 pipettes based upon the largest volume of liquid that is aspirated and disseminated by the pipette. For example the 0.5-10ul micropipette is often called P10 pipette.

Types of Pipette Tips

The Eppendorf Combitip system is designed to meet the needs of any and all modern laboratories. While bulk tips might be the best option out there for labs where the budget is tight, Racked Sterile Tips are a much better option for labs where sterility is paramount and the time of scientists and lab technicians is valuable and there is no extra time available to be constantly refilling and reracking tip boxes every time one is emptied. Filtered pipette tips are a perfect choice tip to utilize while training new individuals who are using a pipette for the first time. The filter inside of these tips will prevent over aspiration of sample up into the inside of the pipette shaft, which will damage a pipette creating high costs.


Types of Micropipette Tips

Air displacement Micropipettes: Air displacement micropipettes are precise and very accurate micropipettes used to measure a liquid volume range from 0.1 – 5000 µ. These micropipettes are available in different sizes from P 2 to P 5000 as mentioned above. These pipettes are used to measure and transfer the volume of liquid with the help of disposable micropipette tips. Positive displacement Micropipettes: Positive displacement micropipettes work on the same principle as air displacement micropipettes do but these micropipettes are less commonly used in the laboratory. These micropipettes are used to avoid contamination of volatile or viscous substances at very small volumes such as DNA contamination. Electronic micropipettes are available both as single-channel and multi-channel micropipettes.


FAQ of Micropipette Tips

What is the difference between micropipette and pipette?

Pipettes and micropipettes are invaluable pieces of laboratory equipment used to draw up, measure, and deliver accurate volumes of liquid. The difference between the two is that micropipettes measure between 1 and 1000µl, while pipettes generally start at 1 milliliter.


Which is more accurate pipette or micropipette?

While there are many measuring glasswares available such as graduated cylinders, beakers, and flasks; out of all, the volumetric pipette is considered the most accurate one for calculating volumetric analysis.


Is micropipette a measuring pipette?

Pipettes that can measure liquid in microliters (μL) with precision, and are most commonly used in experiments, research and analysis in the field of life science.


What does a micropipette 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 supplies are used with 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.
