Biological sterilisation discs are used to perform sterilisation cycle validation in small areas of a device, where a standard-sized spore strip will not fit, such as within a syringe barrel, inside tubing, or under a cap. Spore discs are created by inoculating spore suspensions of certified population and resistance onto paper discs.

• Spore population: 106 spores per disc
• Disc diameter: 6,35 mm
• 24-month shelf life when stored under labelled conditions
