Hi Sony, did you buy it already? I would not autoclave any such a filter, try gamma-irradiation instead. Or purchase sterile ones; there are sterile filters (e.g.Sterlitech) on the market.
Hi, I didn't try to autocalve PTFE and Nylon syringe filters. But, I usually autoclave HTTP membrane (Millipore) and cellulose acetate membrane . You can immerged membranes into distilled water as protecting liquid on the glass garden. sterilize and dry it.
