Three Common Methods of Incubator Sterilization Explained

There are many methods provided by manufacturers to facilitate Incubator self-decontamination. Three of the most common methods are:

1. DNA nucleotides harbor the kinds of conjugated bonds that absorb UV light. UV sterilization generates an antimicrobial effect by the damage it causes to a microorganism’s DNA when aromatic nucleotides absorb high energy photons. This can make UV sterilization an effective solution to reduce contamination in an incubator chamber.

   However, there are significant drawbacks. Your light source would need to have unrestricted access to all surfaces of the Multifunctional Incubator chamber, shelves, and shelf mounting hardware. Shadowed regions will not be decontaminated by UV light. Also, a common method for microorganisms to survive UV exposure is through enhanced DNA repair mechanisms. In this case, survivors of a UV cycle will be more likely to survive repeat treatments.

   Traditional Autoclaves operate by heating to ~121°C and applying elevated steam pressure to increase rates of thermal transmission to targeted contaminant organisms. A moist heat decontamination cycle performed above but close to 100°C and at ambient pressure is guaranteed to be less effective than an autoclave, and does not meet any medical organizational criteria for SAL6 sterilization. SAL6 represents a Sterility Assurance Level of 10-6 meaning you get a Log6 reduction of microorganisms.

   Interestingly, the archaea Geogemma barossii, better known as “Strain 121,” is a species of microorganism that has been shown to grow and reproduce successfully in a pressurized Horizontal Pressure Steam Sterilizer at 121°C.

    

   What are Drying Ovens Used for?

   Despite the fact that most people associate the word oven with the benefits of baking, industrial models are present in food manufacturing, pharmaceutical, and even in painting processes.

   The main job of an industrial Drying Oven is to remove moisture from substances or products. This means that it can be used for evaporation, incubation, sterilization, baking, and many other procedures. Keep in mind that industrial ovens vary in size, capacity, and shape, depending on what they are used for, so the perfect model will depend on the application it is given.

    

   Types of Industrial Drying Ovens

   Even though industrial Hot Air Drying Ovens share the same core concept, there are dozens of different types of technologies available. Industrial ovens vary in heating mechanisms, time and volume capacities, and other key elements, depending on your industry.v

   These versatile machines are used mostly in engineering, research, and other industries that may require drying in a low-pressure environment. Vacuum Drying Ovens also minimize oxidation and may even include an automated digital interface for monitoring purposes.A Test Chamber is a managed and controlled environment used to test the endurance, stability, and practicality of equipment, products, and chemicals. They are a controlled enclosure that mimics the effects of environmental conditions that a product may encounter during its usage. Programmed test chambers create extreme temperature variations, moist or humid conditions, and radical altitude variances.The burst test, seen in this image, determines the amount of resistant pressure this sample of cardboard can endure before it fails, an example of the types of endurance testing performed in Scalable Test Chambers.

   Some of the other purposes for test chambers are:What are the Designs of Test Chambers?

   Walk-in Test Chamber designs vary depending on the types of test they perform, which can be very complex and complicated or extremely simple. They come in various sizes to fit the manufacturer and the desired conditions to be tested such as a bench top for testing small items and room size to fit a car.
