What's the chance of getting away with doing a performic in a stainless steel or PP/PE container.
I have used a SS probe and stirrer shaft with teflon paddle and SS nuts and bolts, never have I seen the slightest bit of corrosion on the steel
although I realise the surface area is very small. But I think I can do it.
I even believe that a plastic container can handle contact with DCM for 24 hours at least once, usually I keep tempretures about 34 - 36 deg C. No
reflux, but I don't know if the product would be contaminated.

316L will suffice. Peracetic has little effect on 18/18 SS. Formic acid itself will even eat Ni.
PP or PE is fine just keep the temp about 30 degrees below the transition temp.

Why do you not want to use glass?

Because I've broken all my 2L flasks, also I was curious to know. What do you mean by "transition temp"?

Glass transition temperature of plastics is the indefinite melting point.
