Vertical autoclaves with super-drying and fast cooling system
Laboratory autoclaves for sterilization processes
In diverse laboratory settings, including those dedicated to healthcare, scientific research, industrial processes, and food safety, the utilization of autoclaves represents a very popular methodology for the eradication of microbial entities from laboratory apparatus, specific consumables, and instruments. The spectrum of items compatible with autoclave sterilization encompasses vitreous and plastic instruments, culture media, a wide variety of metallic instruments, waste bags, and even the specialized garb employed within the laboratory environment.
A laboratory autoclave sterilizes instruments and consumables by generating steam at very high temperatures and pressure, typically ascending to 130-135 degrees Celsius (266-275 degrees Fahrenheit) and 3 bars. This method induces the evaporation of water and the denaturation of microbial proteins, leading to the effective eradication of the microorganisms
It should be noted that certain exceptions exist. Some microorganisms, including prions and spores, exhibit resistance to conventional sterilization techniques owing to their capacity to endure elevated temperatures. Nevertheless, the implementation of more stringent sterilization cycles can guarantee their elimination.
Steam is released into a sealed, pressurized chamber where the items to be sterilized are placed. However, before placing them inside, they must undergo appropriate preparation and arrangement to ensure optimal exposure to the sterilization process.
To this end, materials designed for use in laboratory autoclaves are required. For instance, consumable waste needs to be contained within specially designed autoclavable plastic bags.
Proper processing of the load is crucial. To facilitate this, control tapes designed for autoclaves are employed. These tapes are embedded with a chemical indicator that alters its color upon exposure to the sterilization temperature for a predetermined duration, due to the heat-sensitive nature of these indicators.
Additionally, biological indicators, such as spore tests, are utilized to assess the efficacy of a sterilization process.
The duration required for a lab autoclave to fulfill a sterilization cycle is variable, primarily contingent upon the specific application, the model of the autoclave, and the conditions under which sterilization is conducted. Nonetheless, in the majority of instances, the sterilization phase is expected to span approximately 15 to 20 minutes.
Due to their characteristics and method of operation, autoclaves are not suitable for sterilizing paper or various form of plastics. Consequently, it is imperative to ascertain the compatibility of any instruments with plastic components for autoclave sterilization prior to their placement within the device. Objects made of polypropylene, however, are compatible with sterilization in lab autoclaves.
How does a lab autoclave work?
Lab autoclaves are constructed from stainless steel to withstand high temperatures and pressures without succumbing to corrosion or deformation through successive uses. The best manufacturers work with special alloys such as AISI-316L steel, renowned for its superior durability and resistance. Furthermore, they must be completely hermetic and equipped with devices that monitor the pressure and temperature levels reached within the chamber where the instruments to be sterilized are placed.
Once the instruments are adequately prepared, they are positioned within the chamber. Often, this involves a vertical laboratory autoclave, which is characterized by a door located at its top.
Once the door is closed, the sterilization cycle initiates with the removal of air from the chamber. This is achieved through the autoclave’s purging system, which operates either through gravitational forces or mechanically via a vacuum pump. Subsequently, saturated steam is introduced both within and throughout the load to ensure comprehensive sterilization.
The laboratory autoclave continues this process until it reaches the necessary pressure and temperature for sterilization to occur. At this point, both the pressure and temperature must be maintained steadily until the complete sterilization of all objects is achieved.
Following the sterilization phase, the lab autoclave transitions to drying the materials. This is facilitated by the activation of its heating jacket, which, in conjunction with the generation of a sustained vacuum, effectively removes moist air from the chamber. The synergistic effect of these mechanisms ensures the thorough drying of the sterilized instruments and objects.
Upon completion of the drying process, the load is left to cool until the instruments attain a temperature that is safe for handling. It is only at this juncture that the door is unlocked. Subsequently, the door can be opened to remove the items, which at this point are both perfectly sterilized and entirely dry.
These are the fundamentals of the sterilization process in a lab autoclave.
The parameters such as duration, temperature, and pressure for each phase of the sterilization process need to be meticulously managed, taking into account the nature of the items being sterilized, the urgency of the process, and the specific application of the sterilized items. Despite these variations, the procedural sequence post-loading into the chamber remains largely consistent across most scenarios. Understanding the characteristics of the load and determining the appropriate settings for sterilization in each instance are crucial. Once these factors are established, it is a matter of allowing the process to run and wait the necessary time.
