Elijah, Jackson, and Evelyn are in a lab, and they need to accurately fill a micropipettor. What should they do?

Nora, Luna, and Benjamin are in a science lab. They come across a piece of equipment. Nora thinks it's used to 

Anika is using a P20 micropipette in her biology lab to measure a liquid sample. The P20 micropipette measures volumes from 2-20 microliters. Which of the following volumes could she measure with this micropipette?

During a lab, you need to transfer 4.5 mL of a solution from a 150 mL flask to a 15 mL conical tube. Which of the following would be the best to use?

Imagine Michael, Hannah, and Nora are in a science lab. They need to transfer 1-2 ml of liquid for their experiment. Which tool should they use?

A _________has a cotton plug at the top end to slow water down. In case you overfill this will give you enough time to react and stop/reverse what you are doing before the water enters the barrel of the pipette pump.

Imagine you are in a science lab with Daniel, Abigail, and Ava. You see a piece of equipment and Daniel says, 'We should use this with ___.' What is he referring to?

You should NEVER rotate the volume adjuster on a micropipette beyond the upper and lower limit

Never invert or lay the micropipette down with a filled tip; fluid can flow back into the barrel and contaminate it for future use.

Letting the plunger of the micropipette snap back after withdrawing or expelling fluid won't damage the piston.

You must immerse the barrel of the micropipette in fluid, when taking in liquid

If you place the tip of a micropipette over a flame to sterilize it, it won't melt.

Sophia and Benjamin are having a debate. Sophia says that you should always change out the micropipette tip when changing reagents, but Benjamin isn't so sure. Who is correct?

Micropipettes are very accurate tools of measurement, but they are only as accurate as the person using it.

When expelling a liquid from a micropipette tip, it should be done up against the wall of the receiving container to allow the capillary action to draw out the liquid entirely.
