Younike 20 cubic ethylene oxide sterilization cabinet

Younike 20 cubic ethylene oxide sterilization cabinet

Core advantages of ethylene oxide (EO) sterilization cabinet

one ✅ Low temperature sterilization, does not damage thermal sensitive items

Working temperature is 37-60 ℃, and the entire process is sterilized by cold sterilization at room temperature and low pressure

• No deformation, no aging, no brittleness: plastic, rubber, silicone, endoscopy, electronic precision instruments, optical lenses can all be used

Compared to steam/dry heat at 121 ℃, there is almost no material loss

two ✅ Broad spectrum sterilization,

• Can kill bacterial colonies, fungi, viruses, tuberculosis bacteria, and the most difficult to kill bacterial spores with full coverage

• Up to 10 ⁻⁶ sterile assurance level SAL, the highest medical standard

three ✅ Gas penetration power

Molecules are extremely small, penetrating deep into slender conduits, micropores, complex lumens, and dead corners inside curved lumens

Penetrating sterilization bags, paper plastic packaging, non-woven fabric, multi-layer stacked goods, with packaging for overall sterilization

four ✅ Material compatibility

• No corrosion, rust, or discoloration to metals

Suitable for plastics, rubber, cotton textiles, glass, composite materials, implant consumables, and almost universal for all medical materials

five ✅ Pre packaged sterilization with a long shelf life for sterility

Sealed and packaged items before sterilization, fully unopened throughout the process

Maintain sterility for a long time after sterilization, prevent secondary cross contamination, and facilitate inventory turnover

six ✅ Batch efficient, automated and controllable

• Complete cabinet sizes, capable of mass industrial sterilization in large quantities

Full process computer temperature control/humidity/concentration/time, stable quality, can be verified by dual monitoring of chemistry and biology

seven ✅ Mature and versatile, industry reliable

Global mainstream low-temperature sterilization solutions for medical use, decades of standard processes, and the highest regulatory recognition

1、 Disadvantages of ethylene oxide EO sterilization

1. Toxic and carcinogenic, flammable and explosive

EO gas itself is toxic and highly irritating, belonging to a class of carcinogens; Pure gas is prone to combustion and explosion when exposed to open flames and high temperatures, posing a high safety risk.

Long parsing time and slow shipment

After sterilization, the residual gas inside the product evaporates slowly and requires 7-14 days for routine analysis. Urgent analysis also takes more than ten hours, so it cannot be used immediately after leaving the factory.

3 Not suitable for absorbent materials

Cotton wool, gauze, paper, sponge, and wood will adsorb a large amount of EO gas, and the residue is extremely difficult to dissipate. Therefore, EO sterilization is generally not recommended.

The overall sterilization cycle is very long

Preprocessing → Vacuuming → Humidification → Medication → Insulation and Sterilization → Ventilation and Flushing → Analysis, the entire process takes a long time.

5. Afraid of water and humid environments

The humidity control requirements are strict. If it is too dry, it will not penetrate completely, and if it is too wet, it will easily condense and affect the effect.

6. Special materials for corrosive parts

Polycarbonate PC, some nylon, and natural rubber may experience slight aging, cracking, and discoloration.

7. Strict Environmental Protection and Control

The exhaust gas needs to be specially treated, and the workshop requires explosion-proof, ventilation, and alarm systems. The certificate acceptance is strict.

2、 Daily safety precautions for use

1. The equipment must have an independent explosion-proof workshop, explosion-proof electrical appliances, explosion-proof lamps, and static grounding. Open flames, smoking, and mobile phone open flame operations are strictly prohibited.

Operators must hold certificates, wear gas masks and protective gloves, and undergo regular medical examinations.

Before each startup, check the airtightness to prevent gas leakage, and equip with toxic gas alarms and exhaust systems.

4. It is strictly prohibited to bring water, oil, or wet items directly into the cabinet for sterilization.

After sterilization, it is strictly prohibited to open and use immediately. It must be forcibly analyzed and approved according to regulations before release.

Store EO steel cylinders away from heat sources and direct sunlight, and store them separately in a cool and shaded warehouse.

Regularly conduct biological monitoring, residue testing, and equipment validation to meet the requirements of medical device GMP.

8. Do not sterilize food, naked pharmaceutical products, and oily items.

3、 Minimalist summary version (can directly write materials)

Advantages: Low temperature does not damage the equipment, strong penetration, broad-spectrum killing of spores, wide material compatibility, and long-lasting sterilization with packaging.

Disadvantages: Toxic and explosive, high residue, slow resolution, long cycle, unsuitable for adsorbent materials, safety investment cost
