Verify® 4-Flash Integrator. Provides immediate confirmation that all critical parameters for gravity flash steam sterilization at 270°F (132°C) have been achieved. Correlated to the death kinetics of a biological indicator, the flash integrators are used to monitor ththe flash steam sterilization cycles. Immediate, easy-to-read results. Detects critical sterilization parameter failures (time, temperature and steam quality). Correlated to biological kill. Indicator can be used as a permanent record. Packaging: 100/Box.
