how to differentiate between buret vs. pipet

[gangazi]

Hello I have a question on buret vs. pipet
DAT destroyer gen chem: a student wanted to measure exactly 12.3 ml of a 0.20M NaOH solution. What should she use?
Answer: Buret

Bootcamp: which would be best for a chemist to measure 8.7 mL of a solution?
Answer: Pipet

What should I look for in the question to differentiate between pipet vs. Buret?

This is the biggest question of the century

@orgoman22 Aren't buret meant to be used for titrations vs measuring a solution?

Hello? Anyone?

I emailed @Ari Rezaei about this exact conflict earlier in the week. He spoke with his chemistry guy and responded:

"Here's what Dr. Christiansen had to say about it:
My preference would be the pipet because you don’t have to fill it up full first and then dispense out of it what you want. With a pipet you can just suck up (aspirate) the exact amount you want. I use pipets every day in my lab work for measuring volumes. I never use burettes for measuring and dispensing volumes . . . ever. In fact, I don’t know a single organic chemist who does. We use burettes for titrations only. However, I think either would be equally accurate. It’s just that pipettes are way more convenient and faster."

Yes I completely agree with Dr. Christiansen. I have never ever used a buret for measuring volumes lol.

This is a question from the 2009 DAT, and guess what the answer is? Buret. -_-

The answer is not what the real answer is, the answer is what the DAT test makers want you to say.

If you were to have this question on the DAT, a pippete is for transferring amounts and Burrettes are for measuring amounts.

I strongly agree. The answer is what the author thinks the answer is lol...
