Precision-Engineered for Pathology Safety and Workflow Excellence

Product Overview

As a trusted manufacturer of operating room equipment, we bring decades of expertise in contamination control to the pathology laboratory. The MediShield™ Grossing Workstation is a dedicated specimen processing system designed to protect personnel from formalin exposure and biohazards while enhancing workflow efficiency. Built to surgical-grade standards, this workstation combines robust construction, intelligent ventilation, and ergonomic accessories to create the ideal environment for gross examination and tissue sampling.

Key Features at a Glance

Surgical-Grade Structural Design

• Premium Material Construction: The worktop is fabricated from 304 stainless steel with a minimum thickness of 1.0 mm, ensuring long-term durability and resistance to corrosion from formalin, xylene, and harsh cleaning agents.

• Anti-Reflective Working Surface: The matte finish eliminates glare from overhead lighting, reducing eye strain during prolonged procedures and allowing for accurate specimen visualization.

• Seamless Welding with Chamfered Edges: All joints are ground smooth and edges are precision-chamfered to eliminate sharp corners, preventing scratches and eliminating bacterial harborage points.

• Engineered Drainage Geometry: The worktop is tilted at a 3° to 5° rearward angle with built-in drainage channels, ensuring waste liquids flow quickly and completely toward the collection port without pooling.

• Integrated Storage Solutions: Stainless steel cabinets and drawers beneath the work surface provide organized storage for retrieval tools, specimen containers, and consumables.

• Odor-Containing Cabinetry: Cabinet doors feature a self-closing mechanism with excellent sealing performance, effectively preventing odor leakage and maintaining a clean laboratory environment.

Core Functional Systems

Exhaust and Negative Pressure System

• Flexible Exhaust Hood: A top-mounted exhaust hood is fully adjustable in height and rotatable through 360 degrees, allowing precise positioning based on procedure type and user preference.

• Active Negative Pressure Control: A built-in negative pressure device maintains the workstation interior at a controlled range of -5 Pa to -10 Pa.

• Verified Airflow Velocity: The system delivers air movement of ≥0.3 m/s, ensuring rapid capture and removal of formaldehyde vapors, tissue debris aerosols, and other airborne contaminants.

• Source Capture Technology: The combination of negative pressure and directional airflow ensures hazardous fumes are evacuated before reaching the user's breathing zone.

Water Supply and Rinsing System

• Dual-Control Mixing Faucet: Hot and cold water faucet with intuitive wrist-blade handles for precise temperature control.

• High-Pressure Spray Gun: Delivers rinsing water at ≥0.6 MPa pressure, providing the force needed to thoroughly clean work surfaces and remove adherent tissue fragments.

• Retractable Hose Design: The spray gun features a retractable hose that keeps the work area uncluttered when not in use while remaining instantly accessible.

• Pure Water Interface: A dedicated connection point for deionized or distilled water systems accommodates specialized specimen processing protocols requiring reagent-grade water.

Waste Liquid and Tissue Collection System

• Anti-Clogging Filtration: Guide channels direct waste liquids through a filter device that effectively intercepts tissue debris, preventing plumbing blockages.

• High-Capacity Sealed Collection: A ≥20 liter sealed waste liquid collection bucket is installed at the rear of the workstation for easy removal and disposal.

• Hands-Free Waste Disposal: A foot-operated waste bucket hook mounted on the work surface edge allows for hands-free opening, eliminating contact contamination risks.

• Complete Containment: The sealed collection system prevents odor escape and maintains a hygienic laboratory environment.

Lighting and Ergonomic Accessories

• Cold Light Source Spotlight: Delivers 5000K to 6000K color temperature with flicker-free operation, providing true-to-life tissue visualization without heat-induced specimen degradation.

• Side-Mounted Tool Organization: Tool racks and specimen box placement areas on both sides of the work surface keep frequently used items within easy reach.

• Adjustable Specimen Holders: Securely position specimens of various sizes for optimal examination and dissection, reducing manual manipulation and improving safety.

• Shadow-Free Illumination: The overhead lighting design ensures the entire work surface is evenly illuminated without distracting shadows.

Biosafety Protection Features

Physical Containment Barriers

• Perimeter Splash Guard: A ≥15 cm high splash guard surrounds the work surface, effectively preventing tissue fluids and fixatives from splashing onto users or surrounding areas.

• Optional Transparent Shield: For applications requiring additional isolation, a clear protective screen creates a physical barrier between operator and specimen while maintaining full visibility.

• Aerosol Containment: The combination of physical barriers and negative pressure ventilation ensures comprehensive protection against both splashes and airborne contaminants.

Disinfection and Compliance

• Ultraviolet Disinfection Capability: The workstation can be equipped with UV lamps for timed disinfection of tools, consumables, and work surfaces between procedures.

• GB 19489 Compliance: The entire unit is designed and manufactured in accordance with the General Requirements for Laboratory Biosafety, providing documented assurance of biosafety performance.

• Easy Decontamination: The seamless stainless steel construction with coved corners allows for thorough cleaning and disinfection without hidden accumulation points.
