Why Hospitals and Labs Trust EOGas 4PLUS for Reliable Sterilization

In hospitals and laboratories, where even a microscopic contaminant can endanger lives, sterilization is not just a procedure—it’s a promise. Every instrument, tool, and piece of equipment must meet the highest standard of cleanliness to ensure patient safety and research accuracy.

Among the trusted technologies in sterilization today, EOGas 4^PLUS has earned a strong reputation for its precision, reliability, and safety. Built on Andersen Sterilizers’ decades of innovation in ethylene oxide (EO) sterilization, EOGas 4^PLUS delivers consistent, validated results that hospitals and labs depend on daily.

Understanding the EOGas 4^PLUS System

EOGas 4 is an advanced ethylene oxide gas sterilization system designed for healthcare and laboratory use. It uses EO—one of the most effective sterilants known for penetrating even complex or delicate instruments—to eliminate bacteria, viruses, fungi, and spores without damaging sensitive materials.

Unlike high-temperature steam or hydrogen-peroxide systems, EOGas 4^PLUS operates at low temperatures (around 50°C) and low humidity levels. This makes it ideal for sterilizing heat- and moisture-sensitive items such as plastics, electronics, optics, and flexible endoscopes.

EOGas 4^PLUS serves diverse sectors: hospitals, research labs, dental clinics, and pharmaceutical facilities—all seeking dependable sterilization without compromising instrument integrity.

Why Sterilization Reliability Matters

Reliability in sterilization is non-negotiable. A single failure can lead to infections, compromised studies, or regulatory penalties. In healthcare environments, sterilization is directly tied to patient outcomes; in laboratories, it affects the accuracy of experiments and data integrity.

Because EO is gentle, compatible penetrating, EOGas 4^PLUS terminally sterilizes medical devices that cannot be sterilized using other modalities, making EOGas 4PLUS the perfect complement to any SPD’s infection prevention strategy.

Core Features That Make EOGas 4 Reliable

1. Low-Temperature Sterilization

EOGas 4^PLUS operates at a gentle 50°C, preserving sensitive materials such as plastics, fibers, and electronics. This allows hospitals and labs to sterilize devices that would otherwise be damaged by high-heat methods like autoclaving.

2. Advanced Monitoring and Control

Each sterilization cycle is carefully managed by microprocessor controls that regulate gas concentration, humidity, and temperature. These parameters are continuously monitored and recorded, ensuring repeatable results and full traceability for compliance audits.

3. Built-In Safety Systems

Safety is at the core of this system’s design. EOGas 4^PLUS features EO-Flexible Chamber Technology. Because EO-FCT removes excess air from the flexible chamber, EOGas 4PLUS requires just a microdose (17.6 grams per cycle) of gas to terminally sterilize — even the longest and most complex lumens. Andersen’s patented gas-diffusion technology uses a cartridge system that minimizes handling and eliminates the need for large gas cylinders.

4. Ease of Use

EOGas 4^PLUS simplifies the sterilization workflow. Users can load instruments, start the cycle, and leave the system to run automatically. Sterilization and aeration take place conveniently in the same chamber, increasing safety. Once the process is complete, sterilized items are ready for safe handling without additional steps.

5. Compact and Scalable Design

With its small footprint, EOGas 4^PLUS fits easily into hospital sterile processing departments or laboratory cleanrooms. Multiple chambers can be installed in parallel to increase throughput, offering flexibility as sterilization needs grow.
