Features

Functional Capabilities

Fully Automated Sterilization Process

The sterilizer features a fully automated cycle including preconditioning, vacuuming, gas injection, exposure, and aeration. This ensures consistent sterilization results while reducing manual intervention and operational errors.

Intelligent Control & Monitoring

Equipped with advanced PLC and SCADA systems, the equipment enables real-time monitoring of key parameters such as temperature, humidity, pressure, and EO concentration. It also supports data recording and traceability in compliance with 21 CFR Part 11.

High Safety Protection System

Multiple safety mechanisms are integrated, including gas leakage detection, explosion-proof (ATEX) design, pressure protection, and interlocking systems. These ensure safe handling of EO gas, which is flammable and requires strict control.

Disposable injection device gas sterilizer
Working Principle

EO sterilization is a chemical process that uses ethylene oxide gas to destroy microorganisms by disrupting their DNA and metabolic functions.

 

Preconditioning – Products are conditioned with controlled humidity and temperature to enhance sterilization efficiency

 

Vacuum Phase – Air is removed to improve EO gas penetration

 

Gas Injection – EO gas is introduced at a controlled concentration

 

Exposure Phase – Gas diffuses into products, eliminating bacteria, viruses, and fungi

 

Aeration – Residual EO is removed to ensure product safet

EO gas offers excellent diffusion and can penetrate packaging and complex structures, making it highly effective for disposable injection devices.

 

Applications

Medical Device Manufacturing

Disposable syringes

Injection needles and components

IV infusion sets

Catheters and tubing

EO sterilization is particularly suitable for thermosensitive materials such as plastics and polymers that cannot withstand high-temperature sterilization methods.

Pharmaceutical Industry

Sterile packaging materials

Drug delivery systems
