Hello Chun,

Overall, most antioxidant substances are heat and/or light sensitive. I have not any personal experience with these drugs you mentioned but I would suggest you to check in detail prior to auclaving.

Good luck

Thanks, everyone! I autoclaved both PVP and active charcoal and made my media finally. I will keep you updated to see whether it works or not. 

Hi Chun.

For the question "Can PVP and activated charcoal be autoclaved?"-- there are two things need to be considered: (1) are these materials physically destroyed during autoclave? (2) If not physically destroyed, are the 'quality' of these materials decreased? and how bad? For example, soil can be autoclaved, but sometimes, the quality of the soil decreased because of the beneficial microbes die (for example). You may need to check it out from the company you purchased or review some documents. And as you said " to see whether it works or not", you need a 'control' group to test.

I ve being using activated charcoal for most of my orchids media and I autoclaved it every time we use. It seems ok & the plants grow well.

off course you can...go ahead

You can autoclave your PVP and charcoal, it doesn't cause any problem

PVP and AC can be autoclaved. You may increase the gradients of concentration to 8 or 10 to get the most optimum concentration for your work

Definitely Yes for activated charcoal (we have autoclaved it many times in rooting media with no adverse effect) but not sure about PVP.

for the activate charcoal I always autoclave it for my date palm micropropagation, but for the PVP I never use it.

Yes they can be autoclaved
