If a chemist needed to measure 12.52 ml of solution. the best piece of laboratory equipment is?

C. Pipet
D. Buret

Answer: D. Buret

Destroyer 2010 Ochem # 154

An Organic Chemist wanted to deliver 15.6 of a liquid in an experiment, which should she employ?

B. Buret
C. Pipet

Answer : C. PiPet



When is pipet used and when is buret used?
Only difference I see in those 2 questions are one is just chemist and one is organic chemist.. and 2 decimal place and 1 decimal place.

But I can't really get when to use what

Help me =)

I didn't get the destroyers explanations on those either.

Buret is used in titrations. It has lots of markings from 1 mL to like 50 mL.

Pipet is when you want to deliver some solution from a flask to another flask. They are only marked for 1 measurement like you have separate pipets for 10mL, 20 mL etc. You can't grab a 10mL pipet and dispense 7 mL out of it because there is only one marking.

Yea! I noticed that too!😱 Anyone?

I think those are key words. I think pipets are used to transfer liquids, hence transfer pipets. Burets are much more precise, so the additional decimal place sort of gives it away.

12.5 ODD decimal, --> buret
15.6 EVEN decimal -->pipet

 

[Alpha Centauri]

Seriously guys? What a bunch of weird reasons you guys are giving the guy as an answer

Buret measures to 2 decimal places, pipet measures to 1 decimal places.

Pipet is used to transfer liquid while buret is used to measure liquid

Lol I don't know why I found that to be the funniest explanation

lmao its true tho

 

[Charles_Darwin]

...this is actually a problem lol. DAT Bootcamp's test says the opposite -

Which of the following pieces of laboratory equipment would be best for a chemist to use to measure 8.7 mL of a solution?
The answer was PIPET, not buret.

????????????

Buret measures to 2 decimal places, pipet measures to 1 decimal places.

This debate is still going on huh... I posted the exact same question and someone said its the biggest question of the century loool

 

[fit2]

Nah haha its probably a mistake in 2009. Who in the world would use a burst for such a small amount of liquid when you have a pipet? I suppose paying close attbetion to measure/deliver is something to take note of just in case it shows up

 

[DaddioDan]

I took the DAT on Monday and I'd say it's worth knowing which one you would use.

So does anyone know.....????? How do we know the difference?

Pay close attention to what it's being used for. A buret would be favorable for something like a titration, whereas a pipette would be more useful for simply transferring a quantity of a substance.

I don't think that's right because in destroyer to measure 12.3 ml of a solution you use a buret. I think measure and transfer are the key words lol, but the charles darwin guy above posted the bootcamp question which had the word measure and that was pipet. Maybe that was an error

There is a discrepancy between this question and another question on the 2009 DAT that states the most accurate glassware to use to measure a solution is a buret. I asked Dr. Mike Christiansen, the organic chemistry professor in the explanation videos, what his thoughts were and this is his response: “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.”

The 2009 DAT is known to have several errors in it (click here for more info), and I believe this is another one of them. Burets are commonly used for titrations where an unknown amount of solution needs to be measured. A pipet is more useful for measuring and transferring precise amounts of solution.

Destroyer says otherwise.
