The differences between the transfer Windows and xenon light transfer Windows
There are some differences between VHP transfer Windows and xenon light transfer Windows in terms of sterilization principles, applicable scenarios, and equipment structures, as follows:Sterilization principle
VHP transfer window: Sterilization is carried out using vaporized hydrogen peroxide. Hydrogen peroxide turns into a vapor state when heated. This vapor can penetrate every corner of objects and dissociate highly active hydroxyl groups through complex chemical reactions, destroying cell membranes, lipids, proteins DNA tissues, etc., thereby achieving the purpose of sterilization.
Xenon light transfer window: It adopts pulsed xenon light sterilization technology, using the pulse engineering technology of instantaneous discharge and special inert gas lamp tubes to excite intense white light in the form of pulses. The spectral distribution is similar to that of sunlight, and the light intensity is thousands or even tens of thousands of times that of the sunlight reaching the Earth's surface. The visible light, infrared rays, and ultraviolet rays in pulsed strong light act in synergy with microorganisms, which can destroy the cell walls and nucleic acid structures of microorganisms and thereby kill them.
Applicable scenarios
VHP transfer window: Widely used in places such as biomedicine, food processing, laboratories, and medical facilities that require a sterile environment, it is mainly used to transfer items between different levels of clean areas, ensuring that medicines, food, experimental materials, etc. are not contaminated by microorganisms.
Xenon light transfer window: Mainly used for the transfer of items between clean areas and clean areas, non-clean areas and clean areas, etc. It is often used in micro-technology, biological laboratories, pharmaceutical factories, hospitals, food processing industries, LCDs, electronics factories, and other places that require purification. In addition, xenon light biosafety transfer Windows can also be used in rooms with airtightness requirements in high-level biosafety laboratories, solving the airtightness problem of logistics channels.
Equipment structure
VHP transfer window: It is usually composed of an external structure (a shell made of stainless steel or other corrosion-resistant materials), an internal chamber, a heating system (used to convert hydrogen peroxide into steam), a control system (a touch screen or buttons for operating start, stop and monitor the disinfection process), a sealing system (to ensure isolation from the external environment), etc.
Xenon light transfer window: It generally includes a pulsed xenon light generation device, an internal chamber, a control system, a sealing system, etc. The four corners of its door leaf often adopt a concentric circle design, which makes the airtightness easier to expand and contract, stress-free, and can better ensure the airtightness effect.
Performance characteristics
VHP transfer window: It features low-temperature sterilization, no residue, no toxic by-products, no impact on other items, easy process verification, environmental friendliness, good penetration of high-efficiency HEPA filters, a wide range of microbial sterilization effects, short sterilization time required, no need to provide desiccants and other consumables, and low hydrogen peroxide consumption. However, its disinfection process may be relatively complex and requires a certain amount of time to complete steps such as vaporization, disinfection, and ventilation.
Xenon light transfer window: It has a high sterilization efficiency and can achieve efficient sterilization in a short time. It belongs to cold sterilization technology and causes less damage to items. Pollution-free and will not produce harmful residues; It has self-cleaning ability. After the self-circulation fan is turned on, the cleanliness inside the transfer window can meet the purification requirements. It has strong corrosion resistance and is made of high-quality stainless steel, resistant to disinfectants, cleaning agents, and chemical reagents such as acids and alkalis. However, the equipment cost may be relatively high, and there are certain requirements for the usage environment, such as the need for a stable power supply.
Maintenance and upkeep
VHP transfer window: It is necessary to regularly inspect the sealing performance of components such as hydrogen peroxide storage tanks, pipelines, and valves to prevent leakage. Calibrate and maintain the heating system, control system, etc. Replace filters and other consumables regularly.
Xenon light transfer window: It mainly involves regular inspection and maintenance of the pulsed xenon light-generating device to ensure its normal operation. Check the performance of the sealing system and replace the damaged seals in time. Clean the interior of the transfer window to keep it clean and tidy.
