Can someone please explain when one would use a buret and when one would use a pipet? Destroyer gen chem #108 and orgo #115 both deal with this. One says to use a buret and the other says to use a pipet. I'm not entirely sure why. Thanks

Yeah, Homie, I know this can be confusing. I just use one or two words to distinguish between the two. The Buret is most useful for better accuracy and for weird volume measurements, (e.g. with decimals & so on) because a pipet can lose some of the solution during the transfer. Ever notice how some amount leaks out when a pipet is used. That's how I would do it. Hope this helps and let me know if you need help with anything else and happy studying!

Generally buret = medium-large volumes and pipet = small volumes.

Pipets are no less inherently accurate than a buret, and I believe would be considered more accurate.

Pipets can be designed/calibrated to .25/.5/.1ul -> 10ml


Burets would also be useful for any type of titration where you're not sure how much liquid you're going to use as pipets are an "all or nothing" (generally speaking) instrument where you can use as much of the buret as you need and know how much you used after.
