Mediwish Type IV Peracetic Acid Sterilant — Solution A is the first component of a two-part liquid system. When mixed 1:1 with Solution B, the activated concentrate contains 2.7–3.3% (w/v) peracetic acid and is intended for preparing working solutions for high-level disinfection and liquid chemical sterilization of compatible immersible medical devices.
Solution A for the Type IV two-part peracetic acid system
Mediwish Type IV Peracetic Acid Sterilant — Solution A is the first component of a two-part liquid system intended for professional medical-device reprocessing. Solution A must be combined with Solution B in a 1:1 ratio. After activation, the concentrate contains 2.7–3.3% (w/v) peracetic acid.
Important: Solution A is not a standalone or ready-to-use disinfectant. It must only be used with the corresponding Solution B and prepared according to the current product label, instructions for use and safety data sheet.

Key features
- Two-part activation: Solution A and Solution B are mixed in equal proportions before preparation of the working solution.
- Defined activated concentration: the combined concentrate contains 2.7–3.3% (w/v) peracetic acid.
- Broad-spectrum system: intended to provide bactericidal, virucidal, fungicidal and sporicidal activity when prepared and used according to the validated instructions.
- For heat-sensitive devices: suitable for compatible medical devices that can be completely immersed and processed with peracetic acid.
- Suitable for lumened devices: channels can be processed when they are completely filled and irrigated according to the device manufacturer’s instructions.
General preparation and use
- Confirm that the device manufacturer permits immersion processing with peracetic acid.
- Thoroughly pre-clean, rinse, inspect and disassemble the device as required before chemical processing.
- Wear the personal protective equipment specified in the safety data sheet and work in a properly ventilated area.
- Mix Solution A and Solution B in a 1:1 ratio and prepare the final working solution strictly according to the current instructions for use.
- Verify the peracetic acid concentration using the specified compatible test method before use.
- Completely immerse all compatible surfaces. Remove air from joints, cavities and lumens and ensure uninterrupted solution contact.
- Maintain the concentration, temperature and contact time specified for the intended application.
- After processing, rinse, dry and handle the device according to its manufacturer’s instructions and the facility’s validated procedure.
Safety and material compatibility
- The activated system is a strong oxidizing chemical. Avoid contact with the skin and eyes and avoid inhaling vapour or mist.
- Do not mix Solution A or the activated system with any chemicals other than the specified Solution B and approved dilution water.
- Confirm compatibility with metals, polymers, adhesives, coatings, optics and electronic components before processing.
- Special attention is required for materials susceptible to corrosion, including iron and copper.
- Store the closed original container in a cool, dark, dry and well-ventilated location, away from heat, flames and incompatible chemicals.
- Keep out of the reach of children and restrict handling to trained personnel.
Important limitations
The applicable concentration, dilution, temperature, contact time, reuse period, rinsing requirements and disposal method must be taken from the current label, instructions for use and safety data sheet. Liquid chemical sterilization by immersion does not itself create a protected package for sterile storage. Processed devices must be handled according to the validated clinical workflow and applicable local requirements.
OEM and distributor supply
Mediwish Co., Ltd supplies coordinated Solution A and Solution B systems for distributors, healthcare suppliers and professional reprocessing projects. When requesting a quotation, specify the required quantity, packaging configuration, destination market, documentation and private-label requirements.
Frequently asked questions
Can Solution A be used on its own?
No. Solution A is only the first component and must be combined 1:1 with the corresponding Solution B.
Can the system be used for every medical device?
No. Only devices whose manufacturers permit immersion processing with peracetic acid may be treated. Material and design compatibility must be confirmed before use.
