For tissue culture, it is important to use products that can be autoclaved (121-123 C, 15-30 minutes). I have some old containers that I've been wondering what they were (they have no recycling logo or anything like that), and I suspect they're PET. I asked a few tissue culture people if they've ever used PET containers, and the only reply I got noted that they've melted in the dishwasher, which would presumably rule out autoclaving.
But Wikipedia (great source, I know) suggests the softening temperature (as gauged by the Vicat B scale) is well above that required for autoclaving, AT 170 c.
While I appreciate that PET bottles are more that PET, I would think it would be a major structural component of the bottle, and resist melting at "typical" dishwasher temperatures.
So, in short- any idea if PET plastic would deform under its own weight (i.e., no significant weight added by any contents) at up to, say, 125 C for 20 minutes? TIA.
