If an experiment calls for 0.1 ml of sterile saline solution, which pipette should you grab? Group of answer choices P20 P200 P1000

1. Break Down the Problem

To determine the appropriate pipette for dispensing 0.1 ml of sterile saline solution, we need to understand the volume range that each pipette can handle.

2. Relevant Concepts

• P20 Pipette: This pipette can typically measure from 1 to 20 µl (0.001 to 0.02 ml).
• P200 Pipette: This pipette can measure from 20 to 200 µl (0.02 to 0.2 ml).
• P1000 Pipette: This pipette can measure from 200 to 1000 µl (0.2 to 1.0 ml).

3. Analysis and Detail

• The required volume is 0.1 ml, which equals 100 µl.
• The P20 is too small since it can only handle up to 20 µl.
• The P1000 is too large for this task since its minimum measurement starts at 200 µl.

4. Verify and Summarize

The only pipette that can accurately dispense 0.1 ml is the P200, as it can handle up to 200 µl, making it suitable for 100 µl.

Final Answer

You should grab the P200 pipette for dispensing 0.1 ml of sterile saline solution.
