• too much solution

• too little solution

• either too much or too little solution

Henry, Maya, and Rohan are working in a lab and are having a friendly competition to see who can select the appropriate size of micropipettes for their experiment the fastest. Which sizes should they choose to measure 146 uL (microliters) ______________?

• A PTP (plastic transfer pipette)

• A 5 - 50 uL micropipettor

• A 2 - 200 uL micropipettor

• A graduated cylinder

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 

• measure & transfer large volumes

• measure & transfer small volumes

• spin chemicals/tubes

• sterilize equipment

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?

• 9.8 ul

• 98 ul

• 980 ml

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?

• 25 mL beaker

• 5 mL serological pipette

• 50 mL graduated cylinder

• P10 micropipette

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?

• Graduated Cylinder

• transfer pipette

• micropipette

• serological pipette

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.

• Pasteur pipette

• Serological pipette

• Tip

• Transfer pipette
