These cylindrical, stainless steel closures will reduce the amount of specimen evaporation to about half that of cotton plugs. Ideal for microbiology and other related applications, these non-contaminating closures may be autoclaved repeatedly without losing resilience. The top surface has indentations that permit adequate exchange of gasses under aerobic and anaerobic conditions, yet prevent microorganisms and dust from collecting at the top. Closures are noncorrosive and come with or without three resilient fingers¯ that allow the closure to be adjusted to nominal variations in the outside diameter of the culture tube it is being fitted to. Available lanced or plain, in several sizes.
