Class B oral lab disinfection instrument carrying plate

In the fast-paced environment of a dental clinic, infection prevention hinges on how reliably instruments pass through the sterilization chain. A well-designed carrying tray is more than a simple basket—it must interface seamlessly with ultrasonic baths, washer-disinfectors, and Class B autoclaves. For clinics that demand precision, the Class B dental sterilizer storage shelf and plate offers a sturdy base for instrument sets. When combined with a Type B oral autoclave instrument holder tray, the workflow from cleaning to sterile storage becomes efficient and repeatable. Larger multi-operatory practices often rely on a Class B dentistry steam disinfection rack with tray system to handle multiple cassette loads simultaneously without sacrificing steam penetration. For wall-mounted or cart-based organization, the B-grade dental sterilizing equipment storage bracket keeps these components securely within easy reach, transforming chaotic sterilization rooms into orderly processing zones. Each element must work in unison, and the carrying plate sits at the heart of this integrated disinfection system.

The Class B Oral Lab Disinfection Instrument Carrying Plate is engineered to withstand the physical and chemical demands of daily sterilization without warping, pitting, or losing dimensional stability. Its flat, perforated surface provides an open area ratio exceeding 65%, allowing unrestricted steam circulation that is critical for hollow and lumened instruments such as handpiece turbines and suction tips. The low-profile raised edges—standing just 5 mm above the tray floor—retain small items like burs and endodontic files while still facilitating gloved loading and unloading. Clinicians value the lightweight construction (under 1 kg for the standard size) that reduces fatigue during instrument processing, yet the tray maintains full-load rigidity thanks to its precision-engineered rib pattern on the underside. After sterilization, the plate can be transferred directly to a drying cabinet, wrapped in sterilization pouches, or placed into a sterile storage cabinet, minimizing the risk of contamination during the final handling stage. The tray conforms to ISO 17665 requirements for moist heat sterilization and demonstrates consistent performance even after thousands of cycles at 134°C.

Key design features that set this carrying plate apart include material selection, surface treatment, and geometric details:

• Premium AISI 304 stainless steel with electropolished finish resists pitting, staining, and protein adhesion
• Surface roughness reduced to Ra ≤ 0.8 µm simplifies manual cleaning and enzymatic detergent rinsing
• Fully sealed, one-piece deep-drawn edge profile eliminates moisture traps where biofilm could accumulate
• Stackable design with integrated 4 mm spacer nibs maintains adequate air gaps when multiple trays are nested for drying or storage
• Rounded internal corners and smooth radius transitions protect sterilization wrap from punctures and eliminate hand injuries
• Optional laser-etched serial numbers enable per-tray traceability in centralized sterilization tracking systems
• Chemical-resistant surface withstands common enzymatic cleaners, peracetic acid solutions, and alcohol-based disinfectant wipes without degradation

These technical attributes have been validated through third-party testing and the product holds CE marking under the Medical Device Regulation. Below is a detailed specification table for the standard model:

Multiple size variants are manufactured to accommodate specific autoclave chamber dimensions, including formats of 300 mm × 200 mm, 450 mm × 250 mm, and 500 mm × 280 mm. Each carrying plate is individually wrapped with protective film and packaged in reinforced cartons to prevent cosmetic damage during transit. For large-volume oral surgery centers and dental university labs, custom engraving and dedicated tray identification labels can be arranged at the production level. Regular inspection of the tray base for any mechanical deformation and routine passivation are recommended to maintain a service life exceeding 5,000 cycles.
