Doctoral Student: Should I purchase my own supplies?

Hey AskAcademia,

My adviser and I have had an extremely rocky relationship, including some sexual harassment shit in the lab that didn't go over well... I was harassed, he sided with the guy, later apologized for not handing it well, but then started to give me an extremely cold shoulder. I successfully completed my comps and had my proposal approved by my committee (and him), but now he is ignoring my emails and will not purchase the supplies I need to do my research. I have about $3,000 worth of supplies needed to complete the analyses on the samples I collected (which was extremely difficult to do). I'm toying with the idea of taking out a loan or putting it on credit just to get the supplies I need. I know it isn't a cost issue for him since he has been spending loads of money on frivolous stuff that the lab doesn't really need. My other committee members seem very supportive. I'm determined to get this degree. Should I do it? What ethical issues may make this a bad/good decision? I can use all the advice I can get.

One of the main purposes of the supervisor is to provide you with working conditions. If the groups has money and it's something needed for your thesis, don't stop until you get him to buy it. Save every instance of communication in case there's shit after, and see if you can get some of the supportive committee members to help.

Don't let the cheap bastard have his way, PhD salaries are low as is, it's really not your obligation to buy lab supplies. Depends on the University, but here in Europe we have quite a lot of mechanisms to report the unproffesional behaviour in superiors...
