The RSA™ or Reduced Surface Activity autosampler vials are Pyrogen Free when manufactured as they are produced sterile and are never touched by “human hands”. They are then packaged, including shrink wrapped in a sterile, class 100,000 clean room environment.
We do not classify these vials as Sterile for sale since the packaging is not sterilized before use. However, this can give you a very good idea of the cleanliness if you wished to \Sterilize them. The entire manufacturing process is ISO Certified.
