Wow, this thread is so full of misinformation. People need to stop posting when they cant give accurate information as it is dangerous and not fair to people coming here for help. I suggest you guys read all the info on Skunk Pharm Research, followed by everyone of the posts applicable to this...

Here guys... http://www.2spi.com/catalog/plasticware/PTFE-labware-jars.php Problem solved:tup:

We were talking about the larger 400ml low form dishes but, that post was one of the posts that got me searching. And, I just joined:rockon:

I was the first to suggest it in this thread. I had never seen anyone use one before and found them so I figured I would share as anything that can make things safer and easier is a good thing for everyone imo. I will let you know if its flexible although I am confident the freezer trick would...

Check these out. They go all the way down to 15ml. http://www.2spi.com/catalog/plasticware/PTFE-labware-jars.php A little pricey but, just like Oil Slick Stacks only much safer being solid PTFE vs. silicone.

Here is another that is even larger at 136mm diameter x 40mm height (400ml volume). Ignore the pic as it is generic. http://www.amazon.ca/SEOH-Evaporating-Spout-136mm-400ml/dp/B00LA7RAOG/ref=sr_1_12?ie=UTF8&qid=1412290910&sr=8-12&keywords=ptfe dishes

The bigger ones listed are just over 5 1/4 inches in diameter so(actual size Height-40mm x Diameter-136mm 400ml), they would work for smaller batches or where fast evap times arent required. We are still looking for a pie plate size although it would probably not be cheap as even these ones are...

Nice find, those would be ideal for storage:tup:

I am just going by what others say as I am new to the PTFE sheet craze and havent tried it. But, either way finding something that isnt consumable should be our goal as unlike parchment paper, PTFE is not something we want to be filling our landfills with.

The problem is other then using a very large sheet, you need a rim on whatever you are using to contain the fluids being evaporated which means lining another vessel with whatever film you are using. This wears out thin films like the OIL Slick sheet and I assume would with thicker ones as well...

If anyone is interested, some one I know is going to test a 400ml PTFE evaporation dish vs. an Oil Slick sheet lined Pyrex dish. I will report results when I hear from them.

It is made of solid PTFE so it should still be a huge improvement over glass(even if it is not flexible)as it is way, WAY more slick(there are very few materials that will permanently adhere to PTFE). I would hypothesis that putting the dish in the freezer for a couple of minutes and using a...

Yeah, it seams to me that these would work a lot better then PTFE film in every area but, possibly dried material removal and a little shot in the freezer should take care of that. The problem with PTFE film is it is a pain in the ass to line a dish with it and wears out from creasing. These...

Hey guys, just wanted to throw another idea out there before you stock up on PTFE film. You can buy PTFE evaporating dishes that are a low wall dish made of pure PTFE just like these films. These dishes are specifically designed for evaporation of chemicals and should be perfect for smaller...

Nice work Diehard, looks nice:tup:. I would stick to the glass tube if I were you though man. Copper is not safe dude, why take the risk? Here is a chemical compatibility program for ya... http://www.coleparmer.ca/Chemical-Resistance I personally would not blast though anything other then...
