Universal Metal Filter Retention Plate for Sterilization Container Round 7-1/4"

• Fits most standard circular openings commonly found in surgical-grade rigid containers.
• Intended Use: Disposable Paper Filters ONLY
• Diameter: 7-1/4 inches
• Filter Retention

A Universal Metal Filter Retention Plate for a 7-1/4" round sterilization container is a critical accessory used to securely hold sterilization filters in place during processing cycles. This component is typically installed inside the lid or base of a rigid sterilization container, aligning over the filter area to ensure that the filter remains flat and sealed throughout the autoclave cycle. The retention plate prevents shifting or displacement of the filter due to pressure changes, steam flow, or handling, which is essential for maintaining the integrity of the sterile barrier system.

Designed for compatibility with round sterilization containers, the 7-1/4" size suggests it fits standard circular openings commonly found in surgical-grade rigid containers. These retention plates are often labeled as “universal” because they can fit a variety of container brands and models that share common sizing and mounting features. Made from medical-grade stainless steel or anodized aluminum, they are corrosion-resistant, reusable, and able to withstand repeated high-temperature sterilization cycles without deforming or degrading. Their perforated or slotted design allows for the free passage of steam or gas while securely clamping the filter against the container wall.

In practice, the Universal Metal Filter Retention Plate supports proper sterilization by ensuring that the filter media—usually made of paper or synthetic fiber—remains in its intended position, forming a consistent barrier that prevents contamination post-sterilization. Without such a retention mechanism, filters could become loose, fold, or shift during processing, compromising sterility assurance. Sterile processing departments (SPDs) rely on these plates to maintain standardized workflows, reduce the risk of wet packs, and ensure compliance with infection control standards. As a result, they play a small but vital role in maintaining the safety and effectiveness of surgical instrument reprocessing.

These surgical instruments have been previously used and show visible signs of wear consistent with their prior usage. Despite these signs, they remain in a usable condition, suitable for continued medical procedures.
