Vacuum pumps for table top steam autoclaves

Product catalog summary

Overview: This brochure provides detailed information on vacuum pumps designed for table top steam autoclaves, focusing on their role in the steam sterilization process, particularly using the fractionated pre-vacuum method.

Steam Sterilization Process: Steam sterilization is an effective method for neutralizing microorganisms, requiring saturated steam generated from boiling water. The efficiency of the sterilization process is linked to the temperature and pressure relationship of the steam, with lower temperatures and pressures leading to faster cycles.

Fractionated Pre-Vacuum Process: According to European Norm prEN 13060, the fractionated pre-vacuum process is essential for achieving the highest sterilization level (class-B standard). This involves multiple evacuations of the chamber, alternating with the intake of saturated steam, facilitated by a vacuum pump that can pass the Bowie-Dick test.

Pump Specifications: The brochure details several diaphragm pumps, highlighting their suitability for autoclave applications due to their heat resistance and reliability. Key models include:

7006 Series: Offers free flow rates of 7.2 to 15.5 l/min, with maximum vacuum levels ranging from 80% to 94%. Designed for consistent performance in demanding autoclave environments.
2119VCDU20: Provides a free flow of 19 l/min and a maximum vacuum of 91.4%, with a robust design for reliable operation.
8011 Series: Features free flow rates of 34 to 65 l/min and maximum vacuum levels up to 99%, suitable for high-demand sterilization processes.

Technical Data: Each pump model is accompanied by detailed pneumatic, electrical, and general data, including motor type, nominal voltage, power consumption, and material specifications. The brochure emphasizes the importance of selecting the right pump for specific autoclave applications.

Conclusion: Gardner Denver Thomas GmbH positions itself as a leader in providing specialized diaphragm pumps for autoclaves, leveraging over a decade of experience and engineering expertise to meet the needs of sterilizer manufacturers worldwide.

Vacuum pumps for table top steam autoclaves-2

Steam sterilization is one of the best methods to neutralize micro-organisms. For a safe sterilization process only saturated steam should be used. This is pure steam generated from boiling water. Saturated steam shows a firm temperature-/pressure-curve (see diagram below). For example to reach a steam pressure of 100 mbar (absolute) a temperature of 46 °C is required. This temperature/pressure relationship is also the key to a very efficient sterilization process. The lower the steam temperature and the corresponding pressure (vacuum) level the faster the sterilization cycle. THOMAS by Gardner...

Steam sterilization with the fractionated pre-vacuum process Fractionated pre-vacuum process According to the preliminary European Norm prEN 13060-1..4 the fractionated pre-vacuum process is absolutely necessary to achieve the highest sterilization level possible, the so called class-B standard. The chamber is evacuated several times (air removal) while alternating with the intake of saturated steam. This job can be done with a vacuum pump enabling the pump to pass the Bowie-Dick test required by prEN 13060. In addition the vacuum pump provides the post-vacuum for the load drying phase of the...
