Question

a ________ pipette is designed to deliver a single volume precisely.
select one:

○ graduated
○ mohr
○ volumetric
○ measuring
○ none of these

Explanation:

To solve this, we analyze each option:

• Graduated pipettes are for measuring variable volumes (with graduations for different amounts).
• Mohr pipettes are a type of graduated pipette, also for variable volumes.
• Volumetric pipettes are designed to deliver a single, precise volume (they have a single mark for a specific volume).
• Measuring pipettes are similar to graduated ones, for variable volumes.

So the correct option is the one related to delivering a single precise volume.

Answer:

C. volumetric
