Micropipette Usage and Features

David and Mary Lou introduce micropipettes, essential tools in biotechnology for transferring small fluid volumes. They explain the operation, types, and volume ranges of micropipettes, emphasizing the importance of selecting the correct type and setting the window for accurate measurement. The video also covers the use of sterile tips to prevent contamination and encourages viewers to familiarize themselves with different micropipettes. The tutorial concludes with an invitation to explore more resources on Lab Exchange.

What is the primary function of a micropipette?

• To heat samples

• To mix chemicals

• To transfer very small volumes of fluid

• To measure large volumes of liquid

How does a micropipette differ from a traditional pipette?

• It uses a plunger instead of a bulb

• It is used for heating samples

• It is larger in size

• It is used for solid samples

Which micropipette size is used for measuring up to 20 microliters?

• P1000

• P200

• P20

• P500

What does the top digit in the window of a P200 micropipette represent?

• Ones

• Thousands

• Hundreds

• Tens

Why is it important to use the correct tip size for a micropipette?

• To reduce the weight of the micropipette

• To change the color of the liquid

• To ensure accurate volume measurement

• To increase the speed of pipetting

What is a key reason for not touching micropipette tips with your hands?

• To prevent cross contamination

• To change the tip color

• To keep the tips warm

• To make the tips more flexible

What should you do if a micropipette tip does not fit properly?

• Force it onto the micropipette

• Use a different micropipette

• Select a different tip size

• Ignore and continue using it

Why is it important to familiarize yourself with different micropipette models?

• To memorize their serial numbers

• To learn their brand names

• To understand their specific features and ranges

• To know their color

What might vary between different micropipette models?

• The color of the liquid they measure

• The number of digits in the window

• The type of liquid they can measure

• The temperature they can withstand

What is a common feature of all micropipettes regardless of their model?

• They all have the same color

• They all measure the same volume

• They all have a window for setting volume

• They all have the same number of digits
