Medical Vacuum

Vacuum Instrumentation for Medical Vacuum Drying and Sterilization | Rough Vacuum Applications | 1 Torr to ATM

Sterilization for medical equipment is vitally important since this process is used to render a product free from viable microorganisms. Steam is used in the many  sterilization processes. The steam is put under pressure that is higher than the atmospheric pressure (> 1 bar).

Need for Medical Vacuum Control

  • In a fractionated (pulsed) vacuum process steam is admitted into the sterilizer chamber after evacuation and immediately afterwards the steam-residual-air mixture is removed again.
  • Wrapped medical items must be dried before they can be aseptically removed from the sterilizer. An example of this would be medical catheters that are used for one-time use. During the sterilization phases condensation results, and vacuum drying is needed to effectively complete the process.
  • vacuum level of 1.0 to 2.0 psia (6.9 to 13.8 kPa) is recommended for efficient drying. At 1.0 psia (6.9 kPa) chamber pressure, water boils at 38.7°C (101.7°F).

Quick Conversion to Torr

1 PSI = 6.8 kPa = 51.7 Torr
2 PSI = 13.7 kPa = 103 Torr
Consistent and reliable vacuum pressure is required to complete the vacuum drying process.
DigiVac has been a vital component in sterilization of medical devices for more than a decade.
