Silicone Sponge Plugs are the ideal replacement for cotton plugs when working with aerobic cultures. They cut losses due to evaporation in half in comparison to cotton plugs, thus minimizing changes in pH values. They can be dry heat sterilized repeatedly at 180ºC and are easy to clean and maintain.
