Breakdown of Prevacuum vs. Gravity 

  • Gravity - designed for sterilization of liquids in flasks with vented closures, at 250°F (121°C), and also heat- and moisture-stabile goods at 270°F (132°C).
  • Prevacuum – designed for efficient, high-volume processing of heat- and moisture-stabile materials, such as fabrics, wrapped hard goods, glassware or animal bedding, at 270°F (132°C). Prevacuum units will also run gravity-type cycles.

Gravity units operate by the gravity downward displacement air-removal principle. Prevacuum sterilizers have a chamber evacuation system for high-speed, high-volume sterilization. Both types use steam-under-pressure as the sterilizing agent.

 

All processing cycles factory programmed into the sterilizer control have been validated to AAMI ST8.

Prevacuum configuration sterilizers are factory programmed with the following cycles:

270°F (132°C) Prevacuum (with either 5-minute or 20-minute dry phases) – For efficient, high volume processing of heat- and moisture-stable materials, such as fabrics and wrapped hard goods. This process incorporates a series of pressure/vacuum pulses to condition the load prior to sterilization. Sterilize temperature: 270°F (132°C) – Sterilize time: 4 minutes – Dry time: 5 minutes or 20 minutes

Gravity, Liquid, 250°F (121°C) – For sterilizing fabrics, Sterilize temperature: 250°F (121°C) – Sterilize time: 30 minutes – Dry time: 15 minutes (Note: A gravity cycle, adjusted to 270°F for 25-minute sterilize exposure time, can be used for processing fabric packs.)

270°F (132°) Gravity Cycle: For sterilizing hard goods. Sterilize temperature: 270°F (132°C) – Sterilize time: 15 minutes – Dry time: 30 minutes (Note: 270°F temperature must be set by the user)

SFPP configuration sterilizers are factory programmed with the following cycles: WRAP/SFPP, SFPP, Prevacuum, Gravity, Liquid and Test Cycles.

Note: SFPP Cycle: For efficient, high-volume processing of porous loads. This process incorporates a series of steam flushes and pressure pulses at pressures above atmospheric levels to condition load prior to sterilization.
Sterilize temperature: 270°F (132°C) – Sterilize time: 4 minutes – Dry time: 20 minutes

WRAP/SFPP Cycle: For efficient, high-volume processing of heat- and moisture-stable materials, such as double wrapped instrument trays. This process incorporates a series of steam flushes and pressure pulses at pressures above atmospheric levels to condition load prior to sterilization. – Sterilize temperature: 270°F (132°C) – Sterilize time: 4 minutes – Dry time: 20 minutes

Liquid Cycle: This cycle is used for sterilizing liquids in borosilicate containers with vented closures. » Sterilize temperature: 250°F (121°C) – Factory programmed sterilize time: 45 minutes – Dry time: not applicable

275°F (135°C) Prevacuum Cycle: This cycle is used for efficient, high-volume processing of heat- and moisture stable materials in double-wrapped instrument trays. This process incorporates a series of pressure/vacuum pulses to condition the load prior to sterilization. » Sterilize temperature: 275°F (135°C) » Sterilize time: 3 minutes » Dry time: 16 minutes
