the sterilization transfer windows a few cons
the sterilization transfer windows a few consThe advent of the product system solved this confusion. While the sterilization transfer windows can pass on the sterilization of a variety of items, new standards have emerged that have challenged the chemical hydrogen peroxide (VHP) transfer windows.1, VHP transfer window sterilization cycle is still too long, from the start of the sterilization to the discharge of the residue to less than 1ppm, generally, small compartments need 1.5 hours, and large compartments are more likely to take about 3 hours. The time cost is too expensive. To reduce the cycle time, some companies may open the hatch to collect materials when the residue in the VHP window is still 5-10 ppm. Increased risk to personnel. 2, the principle of the VHP transfer window is to flash 30% hydrogen peroxide into hydrogen peroxide gas by high temperature flashing, in the whole process of sterilization, it will lead to the temperature of the transfer window rising 5 ℃ -15 ℃, it is not suitable for biological products and other products that are particularly sensitive to the temperature of the transfer. If the transfer window does not warm up, high-temperature hydrogen peroxide gas is extremely easy to attach to the stainless steel plate inside the transfer window to produce condensation. 3, the current domestic VHP transfer window is used on the market common 30% ~ 35% food-grade (or analytical purity level) hydrogen peroxide solution, 30% hydrogen peroxide is a hazardous chemical, flammable, and explosive, and the purchase, transport and storage need to go to the local public security department for the record. And this food-grade or analytically pure level of hydrogen peroxide impurities, the life of the hydrogen peroxide flash tray damage. Is there a sterilization cycle can be shorter, the temperature will not rise, and not need such a high concentration of hydrogen peroxide solution can be achieved 6 logarithmic thermophilic fat bacillus sterilization effect of hydrogen peroxide transfer window, to help the time, the problem of the urgent needs of the enterprise. |
