MESA PS-5-50

ProSpore Ampoule are self-contained biological indicators ideal for validating the sterilization of liquid loads, though they are also suitable for loads containing dry goods. Simply expose the unit to the sterilization process and incubate afterwards. They are validated for 48 hour reduced incubation.

• No activation is required
• Hermetically sealed, type I borosilicate ampoule
• Negative controls available (for 1mL)

The negative control is a media ampoule made from the same lot of media used to make the corresponding spore ampoules. The ampoule is filled with a modified soybean casein digest broth containing bromocresol purple acid indicator. Each ampoule also contains a population of G. stearothermophilus spores. Growth is evident by either turbidity and/or a color change from purple to or toward yellow.
