Put the statements in order to describe the correct actions in the use of micropipette to dispense 95 ul from a microfuge tube containing water into an empty microfuge tube 8 a Step 1 - Use the dial to set the micropipette to the correct volume For your answer rearrange the order of the lettered statements to write the correct order of the remaining steps.
The micropipette is used to transfer small amounts 1 ml of liquids. Grade Levels 9-12 Learning Objectives 1. The Molecule of Life Think for a moment about all the different types of life that exist on our planet.
When not in use to prevent airborn contamination. Make sure you are using the correct pipet for the intended volume. 74 Identify and demonstrate proper use of micropipettes Proper use of micropipettes.
It might be surprising to know that the basic blueprint for this life is found in a tiny molecule. Open the box without touching the tips with your hands. Precise results are reproducible.
Perhaps some pipetting technique variation is even expected. Micropipette tips are usually bought in racks which can be placed in a box and used in a. She also demonstrates the proper techniques fo.
In here we describe how to use both a micropipette and a pipette. Micropipette Centrifuge Spectrophotometer pH meter. Slowly release the button to its original position then pause for a second.
These differences may seem normal and insignificant. Best Practices for the Use of Micropipettes When it comes to pipetting technique minor variations can have major consequences. Lets use a target analogy to demonstrate the difference between accurate and precise results.
This will attach the tip to the shaft. Obtain the micropipette tips that match the micropipette you will need to use. Demonstrate proper use of compound microscope.
Use biotechnology laboratory equipment correctly and safely. Identify and describe the proper use of basic equipment found in a biotechnology laboratory. Describe how to make solutions from either solid chemicals or liquid stock solutions.
There are so many different types of laboratories and in all of them people have to work with liquids and semi liquids. Inserting the Tip 1. Each micropipette has a digital readout of three to four numbers corresponding to different volumes.
A micropipette is an instrument that measures volume with great accuracy. Place tip about 2 mm into liquid you intend to draw. 75 Identify and demonstrate proper use of spectrophotometers including creating a standard curve relating absorbance and concentration Proper use of spectrophotometers including creating a standard curve.
