Newcomer Lab Skills: Micropipette

Helo Class,I am so sorry that I will not be with you until next week, but don't feel well at all. When I come back on Monday we will be doing this, so take notes and be prepared. It can be tricky, but it is a lot of fun once you get the hang of it. Mrs. Reigel Understanding Micropipettes: A Key Tool in Science Micropipettes are essential tools used in laboratories to measure and transfer small volumes of liquid, typically ranging from 0.1 microliters to 1000 microliters (1 milliliter). They are crucial in various scientific fields, including biology, chemistry, and medicine. Micropipettes are invaluable tools in many scientific applications. Understanding how to use them correctly ensures accurate results in experiments and tests. By avoiding common mistakes, scientists can make reliable discoveries that impact various fields. Read more about them in the space below:Structure:A micropipette consists of a slender tube, a plunger, a tip, and a volume adjustment dial.Function: The plunger creates a vacuum that draws liquid into the tip when pressed and released. The volume adjustment dial allows users to set the desired amount of liquid to transfer. Steps on How to Use a Micropipette When looking at the various levels for the plunger at the top of the micropipette make notes of the various levels it moves through: the color blue is 'release', green is the first stop, and red is the second stop. Select the Appropriate Micropipette: Choose a micropipette based on the volume of liquid you need to handle.Adjust the Volume:Turn the volume adjustment dial until the desired volume is displayed in the window. Typically, Mrs. Reigel will do this for you as each micropipette looks a bit different.Attach a Tip:Firmly press a disposable tip onto the end of the micropipette.Draw Up the Liquid:Press the plunger down to the first stop.Place the tip into the liquid and slowly release the plunger to draw liquid into the tip.Dispense the Liquid:Move the micropipette to the desired container.Slowlypress the plunger down to the second stop to release the liquid completely.Eject the Tip:Press the tip ejector button to dispose of the used tip safely.Mrs. Reigel will tell you when to discard your tip. How to use a micropipette Watch the video below that shows you these steps in action. Common Mistakes Made by Students Going to The Wrong Stops: Failing to follow the stop procedure can lead to inaccurate dispensing of fluids.Incorrect Volume Setting: Setting the wrong volume can cause either too much or too little liquid to be transferred.Using a Damaged Tip: A cracked or damaged tip can result in leaks and inaccuracies. Real-World Applications Medical Testing: Micropipettes are used in labs for tests such as blood analysis and disease detection.Drug Development: They help in preparing samples for experiments to develop new medications.Environmental Science: Micropipettes assist in analyzing samples from water or soil to detect pollutants. Check off all of the tasks that you completed: I read everything. I watched the video. I took notes.
