The low temperature hydrogen peroxide plasma sterilizer is suitable for rapid sterilization of various medical surgical instruments in hospital operating rooms and disinfection supply centers. Microcomputer control, touch operation, automatic lift door.

The low-temperature hydrogen peroxide plasma sterilizer generates plasma through the action of high-frequency electric field in the disinfection chamber under low temperature and vacuum state, in which the active substance chemically reacts with the protein and nucleic acid in the microorganism, destroying the microorganism and disturbing the microorganism the survival function, and then use H₂O₂ as a medium to act on the microbial cells to further kill the microorganisms.

Items and materials that can be sterilized

Hysteroscope, laparoscope, laryngoscope, probe, rigid endoscope, flexible endoscope, ophthalmic lens, fiber optic cable, intracranial pressure sensor, cryotherapy probe, prostatectomy device, esophagus dilator, electrocautery instrument, Vibration motor, laser head, metal, glass, silicone, rubber, etc.

Consumables: hydrogen peroxide sterilant, plasma biological indicator, plasma chemical indicator card (label), plasma indicator tape, non-woven fabric, plasma medical packaging bag, etc.

Technical advantages

  1. Low temperature sterilization:

Sterilization temperature is 50℃±5℃, low temperature without humidity, no damage to sterilized items and instruments.

  1. Green and pollution-free:

The sterilant uses hydrogen peroxide solution, no toxic substances remain, no drainage or exhaust, and no damage to the operator’s body. There are filters at the air inlet and exhaust port, which can fully absorb the H₂O₂ removed during the vacuum residue removal process. No pollution to the environment.

  1. Sterilization and stability

The sterilization room is made of aluminum, which has the properties of anti-corrosion and fast heat conduction, which makes the temperature of the sterilization room more balanced and ensures that the H₂O₂ remains full and gaseous throughout the whole process. The hydrogen peroxide low-temperature storage system ensures that the concentration of hydrogen peroxide is stable and effective, and does not volatilize.

  1. High sterilization efficiency:

The design of the rectangular sterilization chamber makes it more convenient to load more instruments at one time, which improves the usable space of the sterilization chamber.

  1. the safety and stability of the sealed door:

The electric lift door is used, which runs smoothly and has a safety interlock device to avoid potential safety hazards caused by misoperation of equipment and operators.

  1. safe operation is simple:

Adopt high-intelligent control processor, one-key start, convenient operation, and it can be used after power on.

  1. Configuration:

The selected configuration has smooth compatibility. Control system, vacuum pump, pressure sensor, solenoid valve and other key hardware are all good components. Diversified program selection, control system can be maintained.

  1. save time and money:

The sterilization cycle is short, sterilization is completed within 55 minutes, and it can be used directly without any treatment. The cost of each sterilization is low, which can improve the turnover rate of sterilized instruments and reduce costs.

  1. the air inlet is equipped with a sterile filter:

It can effectively filter germs and microorganisms to avoid secondary pollution when discharging residues.

  1.  U disk storage function:

The disk capacity is ≥8G, and it can store and record ≥1 million sterilization data. The stored information includes program serial number, sterilization date, sterilization pot times, sterilization start and end time, and pressure, temperature, stage time and end of the sterilization process status, etc.
