Yes.
Some examples of media that are not autoclavable include heat-sensitive materials like plastics, certain chemicals, and some types of agar that can be altered or degraded by the high temperatures and pressure of the autoclave. It's important to carefully check the compatibility of each specific type of media with autoclaving before attempting to sterilize it in this way.
1.) Autoclaving 2.) Dry heat sterilization 3.)bacteriological filter ** UV rays can be used to sterilize but they kill the organisms on the slide...so this practice is not used often only on select organisms that can survivie UV rays
Polypropylene is the most common form of synthetic material used. It is used in almost every thing we use. Though previously declared safe, recent searches reveal that polypropylene may release two highly toxic substances, quaternary ammonium biocides and oleamide.
Polycarbonate products are autoclavable. They must be thoroughly rinsed before autoclaving because detergent residues cause crazing and spotting. Autoclaving cycles should be limited to 20 minutes at 121°C. PC shows some loss of mechanical strength after repeated autoclaving and therefore may not function well under high-stress applications, such as centrifugation.
