Vertical autoclaves with super-drying and fast cooling system
Features of Pre- and Post-vacuum autoclaves
Pre-vacuuming is a crucial phase in the sterilization process. At this stage, the equipment’s vacuum pump mechanically extracts the air from the chamber and the load. This is accomplished through multiple vacuum pulses at -0.75 Bar, interspersed with injections of saturated steam. Typically, this cycle is repeated at least three times to ensure that all the cold air is fully replaced by steam, which is essential for the steam to thoroughly penetrate all objects.
The pre-vacuum phase is essential for sterilizing objects such as wrapped solids, textiles, porous loads, and especially medical instruments with complex cavities and geometries. This phase is fundamental because, in its absence, ensuring thorough steam penetration into materials with minute cavities would be problematic, potentially leading to incomplete sterilization.
The cavities within these items trap cold air, which serves as a barrier to water vapor. Without removing this air, the efficiency of the sterilization process is compromised, posing risks of microbiological contamination. The consequences of using a contaminated medical implant in a patient are severe, increasing the likelihood of infection and sepsis dramatically.
As for the post-vacuum phase, also known as the vacuum drying phase, it is conducted on solid loads and takes place after sterilization. Autoclaves equipped for this phase not only have the standard features of a pre-vacuum autoclave but also include a heating jacket and a bacteriological filter. During this phase, multiple vacuum pulses are applied similarly to the pre-vacuum phase. However, the key difference is that hot air saturated with humidity is extracted and replaced with dry, cold air of lower humidity. This incoming cold air is filtered through a bacteriological filter to prevent any contamination of the sterilized load.
The goal of this phase is to eliminate all moisture from the load. To achieve this, the heating jacket is activated during the vacuum pulses, causing any condensed water within the load and on the chamber walls to evaporate. This process enables the vacuum pump to effectively remove all moisture from the autoclave’s interior.
The post-vacuum phase is essential to obtain completely dry and moisture-free loads. If this is not done, any moisture remaining inside these materials and instruments could be contaminated in the future.
Pre and Post-vacuum autoclaves of certified quality
Our Pre and Post-vacuum autoclaves are designed to thoroughly eliminate cold air before the sterilization step and to assure complete drying of the load once the process concludes.
Our range of Pre and Post-vacuum autoclaves includes a wide variety of models, corresponding to the AE-B, AHS-B and TLV-PD Series. These units are equipped with a steam generator and include a fractionated pre-vacuum cycle. Thanks to these characteristics, they excel at sterilizing porous solid materials, wrapped objects and those with intricate geometries, among other challenging applications.
Furthermore, the AE-B, AHS-B, and TLV-PD Series feature vacuum drying at the conclusion of the sterilization phase, effectively removing all moisture from the lead. This guarantees that the sterilized items are completely dry and ready for immediate storage or use once the cycle is finished.
Trust in sterilization equipment is essential for conducting safe and successful sterilizations, as well as for upholding quality in healthcare settings. This reliability is also essential for quality assurance in laboratories and production areas.
That is why for over 45 years, all our Pre and Post-vacuum autoclaves have been designed and constructed at our facilities in Barcelona, reflecting our commitment to quality and our extensive experience.
This equipment is subjected to rigorous testing to ensure compliance with regulations and standards, including the European Pressure Equipment Directive (PED). With this, we strive for the highest levels of production excellence and ensure the safety of our products.
