Container lid and bottom are both of a one-piece construction and have a uniform, anodized aluminum alloy finish. Lightweight yet durable to accommodate weight loads of surgical instrumentation. Handles stop at 90 degress to aid lifting; low profile latch allows simple and secure lid closing. Retention plate employs an easy “click and lock” closure over disposable, quick-to-change filter. Dual silicone gaskets within retention plate and around perimeter ensure complete container and filter seal. Baskets are constructed with solid wire mesh to allow for maximum ultrasonic cleaning. Handles can be positioned to assist with secure and comfortable grasp for removal under sterile conditions.
