How to improve the safety and effectiveness of waste sterilization ——Systec autoclave classic application During the experiment, a lot of waste will be produced. If it is not handled properly, it will pollute the laboratory, affect the normal work of the laboratory, and even endanger the health and life of the laboratory personnel. Therefore, the laboratory waste is very processed. important. Laboratory waste is currently processed primarily through autoclaves. Incomplete exhaust problem (effectiveness) : In the waste sterilization process, the waste must be placed in the sterilization bag, and the cold air in the sterilization bag will be heavier than the steam, and the cold air will deposit on the bottom of the waste bag. Exclude, affecting the sterilization effect. Let's do an experiment and insert three PT-100 flexible temperature probes into the waste bag. The three probes are positioned at the top, middle, and bottom of the bag: as shown. Through our sterilization data analysis software, it was found that the three probes showed a heating rate: the top was faster than the middle faster than the bottom, which verified that cold air was deposited at the bottom of the bag, affecting the entry of steam. When the cavity temperature reached 121 ° C, the three probes in the bag did not reach 121 ° C, and even after the sterilization process, the probe temperature was only 100 degrees, which could not guarantee the quality of sterilization. The use of biological indicators also found that sterilization in discarded bags was ineffective. Red: cavity temperature, black: cavity pressure, green: top temperature, blue: middle temperature, yellow: bottom temperature Systec solution : Optional pulsating vacuum system with independent steam generator for efficient venting. The proven exhaust effect is 99.99% pure steam. Continue the above three temperature probe experiments and found that all three probes in the bag can reach the sterilization temperature (121 ° C) for effective sterilization. Biological indicators also validate our sterilization results. As the most versatile and top quality sterilizer brand on the market, Systec offers the perfect solution for all types of sterilizing substances, providing better advice for your laboratory sterilization.

All wastes to be sterilized that have been prepared are placed in plastic bags of different sizes or in stainless steel cylinders in the main laboratory. Wrap the double-layer autoclave bag before sterilization. The volume of waste in the sterilization bag should not exceed 3/4 of the bag volume. The sterilization bag is bundled with rubber band, but it can't be too dead, otherwise steam Can not enter the plastic bag to affect the sterilization effect. A sterilization indicator tape can be attached to each bag to evaluate the sterilization effect. When the autoclave is sterilized for a period of time, open the autoclave outside the biosafety laboratory and remove the item and place it in the waste collection area.
At present, the sterilization requirements for waste are getting higher and higher. Especially for wastes containing infectious bacteria, the safety and effectiveness of sterilization have received much attention. At present, for the sterilization of waste, there are mainly the following key issues:
Infectious Waste Exhaust Hazard (Safety) : Before reaching the sterilization temperature, the sterilizer must first discharge cold air so that the chamber is filled with steam. Cold air that comes into contact with waste infectious materials is discharged without being sterilized, causing damage to the laboratory or the environment.
Systec solution : The Systec sterilizer can be equipped with a venting filter system with a PTFE pore size 0.2 micron filter membrane. The filter membrane is placed in a pressure chamber for easy replacement. The filter itself can be self-sterilized by steam in the sterilization process, while the inside of the filter contains a PT-100 probe to monitor the sterilization status. During the sterilization process, the gases and liquids of all potentially pathogenic substances are filtered before being discharged, thus ensuring that aerosols and microorganisms will not leak out before sterilization is completed, and the filter element is also in-line sterilized.
