If an experiment calls for 0.9 ml of sterile saline solution solution, which pipette should you grab? Group of answer choices P20 P200 P1000

Break Down the Problem

1. We need to determine which pipette is suitable for measuring 0.9 ml of sterile saline solution.
2. The pipettes available are P20, P200, and P1000. Each pipette has a range of volumes it can accurately measure.

Relevant Concepts

1. P20 pipette: Typically used for volumes from 2 µl to 20 µl.
2. P200 pipette: Suitable for volumes from 20 µl to 200 µl.
3. P1000 pipette: Designed for larger volumes, usually from 200 µl to 1000 µl.

Analysis and Detail

1. Since 0.9 ml is equivalent to 900 µl, we need a pipette that can measure this volume.
2. The P20 and P200 pipettes cannot measure 0.9 ml accurately as their maximum volumes are below 900 µl.
3. The P1000 pipette, however, can measure volumes up to 1000 µl and is therefore appropriate for this experiment.

Verify and Summarize

• The only pipette suitable for measuring 0.9 ml (or 900 µl) is the P1000, as the P20 and P200 are not capable of handling this volume.

Final Answer

You should grab the P1000 pipette for measuring 0.9 ml of sterile saline solution.
