I'd rather go thicker than the film and thinner than a plate that's y I'm looking at the pad sized ptfe that's way it's still flexable to be a liner but stiff enough not to crease. IMO a pad sized thickness is a one time buy also.

Slightly off topic...man, between this thread and the evap chamber (and some others), we dropping some nasty science 'round here! :science:

@Tachead alrighty then...I just told @farscaper in a pm that I might get one to try out...but I may wait to hear from you about what you hear from the person you know running the test.

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. Plus, after a certain thickness you wont even be able to bend or line anything because it will be too rigid. so, I see only 4 options thus far.

1. Use thin PTFE film but, expect it to be an expensive, environmentally harmful consumable.

2. Use a very large PTFE sheet so large that the whole pool will sit on it without a rim(should last forever).

3. Some kind of dish made of PTFE like the ones I have listed(should last forever).

4. Use glass and have fun scrapping:)

So freeze and poke instead of fold, crease and yank. All right I'll try one. I didn't like sheet experience.

do they have any with a .030" or .040" thickness? ive also been waiting to hear from you on the grainger site cause it was a little typofilled and you had been in contact with them.
Click to expand...

indeed they do! when you search on graingers site you have to click on the item and then the description will have the actual size. using the search drop downs makes it look like they only off the thick shit. EG... a drop down selection that says ".300" could actually be .030 or .003. you just have to view that item individually and you get the real thickness. im going to order some of the .004 and .005 to see if it holds up better than osSS.

unlike PTFE film which has a very short service life and is not cheap(its also very bad for the environment, very very bad).

what do you consider a short service life? i have had pieces of slick sheet last months with repeated use before it needs to be tossed.

i do like the idea of the dish though. i am very interested in how the freezer trick will work with it.

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.

So these dishes are big enough to blast/wash right into and evap from there? I didn't get to check their sizes?
Click to expand...

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 in the $60-100 range.

That looks way too deep and narrow. Would be a pita to get oil put of that I'd think.

Besides, I can store a dozen different grams in a single large Jyar by using PTFE sheeting as parchment style storage.

well, do that then... I was only trying to help.

Sorry, I wasnt trying to discount your effort to assist. I was just explaining why I wanted the sheeting versus a "container".

I think a .005 or a little thicker would probably be thick enough to origami an envelope out of it that might stay shut like parchment does when creased. I notice the .003 of the oss does ok though so anywhere you can find .003" thick ptfe film for cheap you should be good to go if you are looking for generic ptfe sheetingto be just like oss for cheaper.

You guys must not look at my links, lol, j/k...I posted back there a couple different 400mL dishes, two different brands, nice that we have a lot of places to get this from, even though it is all pretty much one or two brands.
Oh ya...calling out @herbivore21 again...no tek secrets bro! lol

This discussion is going in a great direction...has made me not think about the evap chamber, lol.
@Tachead, do you have an approximate time frame where you will see your friends results? If it's gonna be awhile, a might just get one these dishes to try

I was reluctant about that dish you posted (its not the first time ive seen it posted either)

until the notice it may be "flexible" now I think its is a very strong possibility!

I think the dish if its flexible is worth the investment since it is specifically an evaporation dish!

I just needed it to be flexible.
