text: naoh (sodium hydroxide)can be autoclaved after added into solution? after had made a solution, can that solution containing naoh be autoclaved at 120oc for 30min? or is there any hazard could damage the high pressure sterilizer machine? or hazard steam? appreciate any advice or comment about it. it should be alright... but how high of concnetration are we talking here? of course there is no need to steralize a concentrated solution of naoh... nothing could live in it. but for normal biological solutions, i don't see a problem.
