• false

Always change out the micropipette tip when changing reagents.

• true

• false

This is a p20 micropipette.

How many microliters will this micropipette take up?

• 500 uL

• 50 uL

• 5.0 uL

• 0.5 uL

When using a micropipette you should go to which stop prior to taking in liquid?

• 1st

• 2nd

• none, enter the liquid first

• either, it doesn't effect your results

What is the purpose of a micropipette?

• To accurately measure and transfer small volumes of liquid.

• To sterilize laboratory equipment.

• To measure and transfer large volumes of liquid.

• To mix chemicals in a laboratory setting.

If a laboratory protocol asks you to add 500 uL of water to a tube, which micropipette should you use?

• p20 pipette

• p200 pipette

• p1000 pipette

If a laboratory protocol asks you to add 21 uL of DNA to a tube, which micropipette should you use?

• p20 pipette

• p200 pipette

• p1000 pipette

Answer explanation

although this is REALLY close to 20, where you could use a p20, remember to never set a micropipette above or below its set range.
