Explore how our labels can satisfy your requirements

ETO indicating dots are an efficient and reliable solution for verifying ethylene oxide sterilization, a critical process in healthcare, pharmaceutical, and laboratory environments. These small, adhesive-backed labels contain materials sensitive to ethylene oxide gas, changing color to confirm exposure and successful sterilization. This visual transformation provides immediate assurance of process completion, enhancing safety and compliance. Our ETO dots streamline the sterilization monitoring process, eliminating the need for manual indicator application and offering a cost-effective solution for maintaining product integrity. Choose our ETO dots for their ease of use and reliability, essential for ensuring the highest standards in product safety and sterility.

  • Ethylene Oxide Sensitivity: ETO dots are designed to be sensitive to ethylene oxide gas, a sterilant commonly used for the low-temperature sterilization of heat-sensitive medical devices and equipment. They change color or provide a visual indication when exposed to ETO gas.
  • Immediate Response: These dots offer a near-instantaneous visual response to the sterilization process, allowing users to quickly assess whether the ETO cycle has achieved proper sterilization conditions.
  • Passive Operation: ETO dots are passive indicators that do not require external power sources or equipment for operation. They provide a straightforward and cost-effective means of monitoring ETO sterilization.
  • Permanent Record: The color change or visual indication on ETO dots is often permanent, providing a long-term record that the sterilization process has been successfully completed.
  • Dose-Response Relationship: ETO dots are designed to have a known and predictable dose-response relationship, enabling users to verify that the sterilization parameters have been met based on the extent of color change or visual indication.
  • ETO Exposure Range: ETO dots are available in various exposure range options to cover different ETO sterilization processes, from low-dose cycles to high-dose cycles.
  • Shape and Size: ETO dots come in different shapes and sizes to accommodate various monitoring requirements and applications.
  • Integration with Packaging Materials: Some ETO dots are integrated into autoclave tape or labels, allowing them to be affixed to the packaging materials of sterilized items, such as autoclave bags or pouches.
  • Healthcare and Medical Settings: ETO dots are commonly used in hospitals, clinics, and healthcare facilities to monitor the sterilization of heat-sensitive medical instruments, surgical equipment, and devices that cannot withstand high-temperature sterilization methods.
  • Pharmaceutical Manufacturing: Pharmaceutical companies utilize ETO dots to verify the sterilization of pharmaceutical products, packaging materials, and production equipment, ensuring product safety and quality.
  • Laboratories: Research laboratories and scientific facilities use ETO dots to validate the sterilization of laboratory equipment and materials that are sensitive to heat, such as plasticware and certain chemicals.
  • Manufacturing of Optical and Precision Instruments: Optical and precision instrument manufacturers use ETO dots to monitor and verify the sterilization of delicate optical devices, lenses, and precision instruments.
  • Quality Control and Compliance: ETO dots play a crucial role in quality control and compliance with regulatory standards, ensuring that ETO sterilization cycles meet established parameters.

1. What are ETO dots?

ETO dots are small, circular indicators used to verify exposure to ethylene oxide gas during the sterilization process. They change color when subjected to ETO, providing visual confirmation that items have undergone the sterilization process.

2. Why are ETO dots important?

They provide an easy and immediate way to ensure that medical instruments, pharmaceuticals, and other sensitive items have been exposed to ethylene oxide for sterilization, which is crucial for maintaining safety and compliance in healthcare settings.

3. How do ETO dots work?

These dots contain chemicals that react specifically to ethylene oxide gas. Upon sufficient exposure to ETO, a color change occurs, signaling that the item has been subjected to the sterilization process.

4. What types of products are ETO dots used with?

They are primarily used with medical devices, surgical instruments, and other products sensitive to heat and moisture, making ETO sterilization a preferred method.

5. Can ETO dots indicate the effectiveness of sterilization?

ETO dots indicate exposure to ethylene oxide but do not directly measure the sterilization effectiveness. They should be part of a broader sterilization validation process.

6. How are ETO dots applied to products?

They are usually adhered to the product or its packaging before undergoing the ETO sterilization process.

7. Can ETO dots be used with other sterilization methods?

ETO dots are specifically designed for ethylene oxide sterilization and may not accurately indicate exposure to other sterilization methods.

8. How should products with ETO dots be stored?

Store them in a cool, dry place away from direct sunlight and extreme temperatures to preserve their integrity until use.

9. Are ETO dots reusable?

No, they are intended for single use. Once they undergo a color change indicating exposure to ETO, they should not be reused.

10. Are there any regulatory considerations for using ETO dots?

In healthcare and pharmaceutical industries, there may be specific guidelines or regulations regarding the monitoring and documentation of sterilization processes. Ensure that the use of ETO dots aligns with these requirements.
