Features

EtO cabinet for medical injection products Key Features

1. Low-Temperature Sterilization Capability

Operating within a controlled temperature range of 30°C–60°C, the system protects heat-sensitive materials from deformation or degradation. This makes it ideal for sterilizing delicate plastic components used in injection products.

2. Excellent Gas Penetration Performance

Ethylene oxide gas offers superior diffusion properties, allowing it to penetrate multilayer packaging and complex geometries. This ensures complete sterilization of internal surfaces, even in narrow lumens or sealed packaging formats.

3. Advanced Process Control System

Equipped with an intelligent PLC-based control system, the equipment enables precise regulation of:

Temperature
Humidity
Gas concentration
Exposure time

All parameters are automatically monitored and recorded, supporting full traceability and compliance with GMP and ISO standards.

4. Uniform Gas Distribution System

The integrated gas circulation design ensures even distribution of EtO gas throughout the chamber. This eliminates sterilization dead zones and guarantees consistent results across all product loads.

5. Enhanced Safety Design

Safety is a critical consideration in EtO sterilization. The cabinet incorporates:

Multi-stage vacuum and nitrogen replacement system
Gas leakage detection sensors
Explosion-proof structural design

These features significantly reduce operational risks and ensure a safe working environment.

Working Process

The sterilization cycle is carefully engineered to optimize efficiency and safety:

Preconditioning

Products are conditioned under controlled temperature and humidity to improve sterilization effectiveness.

Vacuum Phase

Air is removed from the chamber to enhance gas penetration and prevent hazardous mixtures.

Humidification

Moisture is introduced to activate microbial susceptibility to EtO gas.

Gas Injection

Ethylene oxide is vaporized and injected into the chamber at a precise concentration.

Exposure Phase

Products are held under controlled conditions to ensure complete sterilization.

Honor and qualification

Plant area of more than ten thousand square,Wormwood storage capacity is more than 10 times the industry average

Aeration

Final ventilation reduces residual EtO levels to safe limits for handling and use.

Applications

This sterilization cabinet is widely used in the production of:

Disposable syringes
IV infusion sets
Needle assemblies
Catheters and tubing systems
Pre-filled injection devices

It is especially suitable for manufacturers requiring high-throughput sterilization with strict quality control standards.

FAQ:

Q: Can the EtO cabinet be customized based on different medical injection product types?

A: Yes, the EtO cabinet can be fully customized according to the specific characteristics of medical injection products. Parameters such as chamber size, loading capacity, and sterilization cycle can be adjusted to accommodate items like syringes, infusion sets, or complex catheter systems. In addition, the process settings-including temperature, humidity, and gas concentration-can be optimized based on material sensitivity and packaging structure to ensure effective sterilization without compromising product quality.

Q: Is it possible to customize the sterilization process for different packaging formats?

A: Absolutely. Different packaging materials and structures, such as blister packs, medical paper-plastic pouches, or multilayer barrier packaging, require tailored sterilization processes. The system supports flexible configuration of vacuum levels, gas diffusion time, and aeration cycles to ensure proper EtO penetration and residue removal. This customization helps manufacturers meet regulatory requirements while maintaining packaging integrity.

Q: Can the EtO cabinet be integrated into existing production lines?

A: Yes, the system can be designed for seamless integration into existing manufacturing workflows. Custom options include automated loading and unloading systems, conveyor interfaces, and connection with MES or SCADA systems for centralized control. This allows manufacturers to improve production efficiency, reduce manual handling, and achieve full process traceability in compliance with GMP and ISO standards.
