Sadly, my school is broke and we're running extremely short on melting point discs.  Please let me know if you know where I can buy some of these on my own.

I wouldn't mind if you told me where to get good prices on glassware too.  I tend to break things. 

Thanks for any and all help you can provide.

Well, I'm intrigued, what is a "melting point disc'?  A Google search doesn't turn up anything I'd recognize as applicable to lab work.  Who manufactures them?  And what do they do?

Do you mean the ones used for DSC?

It's kind of like DSC, except much more rudimentary.  We use 3/4" diameter glass discs with a small organic sample and heat it to observe its melting point range.  I don't know the brand/model of the discs we're using.  I have the empty case in my locker at school.  Obviously I can find out tomorrow, and I'm sure a brand and model # will make it super easy to find online.

We use those discs like we also use these tubes:

I would use the tubes if our techs knew how to calibrate the melting point devices.  You know something is wrong when the apparatus says room temperature is 5° C.

I assume you're talking about coverslips for a Fisher-Johns mp apparatus. We buy ours from Fisher Scientific (P.N. 12-546)

Squirmy, that looks like what we use.  Wow, it's a lot more expensive than I was hoping for, but I'll have to order those if I break any more of the discs in my locker.

i know, it's sickening!! Science is expensive.
