Question

Properly using a centrifuge requires that several important steps be performed correctly. Choose the three main steps in properly using this piece of equipment. o Using a test tube with approximately the same volume as your sample tube to balance the centrifuge. Placing the test tubes across from each other to balance out the centrifuge. o Placing the test tubes side by side for best separation. o Ensuring the centrifuge is completely stopped before removing samples. o Using the exact same type of test tube and solution in 3-4 test tubes. o Stop the roation of the centrufuge by using a paper towel or stopper until stopped.

Answer 1

To properly use a centrifuge, balance it with equal volume test tubes placed opposite each other, ensure it completely stops before removing samples, and never manually stop the rotation.

Step-by-step explanation:

A centrifuge is a crucial piece of equipment used in laboratories to separate specimens of varying densities through the process of sedimentation. Here are the three main steps for proper usage:

Balance the centrifuge by using test tubes with approximately the same volume, and place them across from each other in the rotor. This prevents the device from being off-balance, which can cause damage or injury.

Ensuring the centrifuge is completely stopped before removing samples is critical for safety and to avoid disturbing the separation process.

Never attempt to stop the rotation of the centrifuge manually, such as by using a paper towel or stopper. Let it come to a stop on its own to avoid damage and possible injury.
