ZEEDO TH-701 Pathology Specimen Dissection Workstation

Overview

The ZEEDO TH-701 Pathology Specimen Dissection Workstation is an engineered solution for safe, ergonomic, and contamination-controlled gross specimen handling in clinical pathology laboratories, academic histopathology departments, and biomedical research facilities. Designed in accordance with international biosafety and occupational hygiene standards—including ISO 15190:2020 (medical laboratories — requirements for safety) and OSHA’s Laboratory Standard 29 CFR 1910.1450—the TH-701 integrates structural integrity, chemical vapor containment, and procedural efficiency into a single-purpose workstation. Its core function is to support standardized grossing protocols: specimen receipt, macroscopic examination, tissue sampling, annotation, and primary fixation—while minimizing operator exposure to formaldehyde, xylene, and other hazardous reagents commonly used in tissue processing workflows.

Key Features

• Monolithic 304 stainless steel construction (1.2 mm gauge), electropolished and brushed finish, providing corrosion resistance against aldehydes, organic solvents, and disinfectants; non-porous surface prevents microbial retention and facilitates validated cleaning procedures.
• Waist-level negative-pressure exhaust system (≥1600 m³/h airflow) with variable-speed centrifugal blower and activated carbon pre-filter; compliant with ASHRAE 110 tracer gas testing methodology for local containment efficacy.
• Dual-temperature water supply system featuring thermostatically controlled heater and insulated PPR piping; includes flexible braided stainless steel faucet with 360° swivel and high-flow laminar delivery for decontamination and rinsing across the full work surface.
• 7° forward-inclined work surface engineered to direct fluid runoff toward integrated PE-lined drainage channels, preventing pooling and ensuring rapid evacuation via corrosion-resistant PE waste piping.
• Integrated spray manifold along lateral edges enables on-demand surface rinsing without manual hose repositioning; nozzles are recessed to avoid interference with specimen handling tools.
• Uniform LED task lighting (≥1200 lux at working plane) with glare-free diffuser and shadow-minimizing positioning—optimized for accurate visual assessment of tissue morphology, lesion demarcation, and ink marking fidelity.
• Modular accessory interface supports seamless integration of optional components: 1080p HD imaging system with HDMI output and on-screen measurement overlay; ANSI Z358.1-compliant eyewash station; touchless infrared hand dryer; and CE-certified tissue shredder with stainless steel cutting chamber and HEPA-filtered exhaust.

Sample Compatibility & Compliance

The TH-701 accommodates human and animal surgical specimens across all major organ systems—including but not limited to gastrointestinal, urological, gynecological, and soft-tissue resections—without dimensional limitation within its 1500 × 800 mm active work area. All wet-process interfaces (faucets, drains, exhaust ducts) are chemically rated for continuous exposure to 10% neutral-buffered formalin, xylene, ethanol series, and chlorine-based disinfectants. The workstation meets structural requirements outlined in CAP (College of American Pathologists) checklist GEN.40550 (Grossing Area Design) and aligns with CLSI GP39-A4 guidelines for biosafety in anatomical pathology settings. Electrical components comply with IEC 61000-6-3 (EMC emissions) and IEC 60529 IP54 ingress protection rating.

Software & Data Management

While the TH-701 is a hardware-dedicated platform with no embedded operating system, its optional HD imaging module outputs uncompressed HDMI video and JPEG stills compatible with DICOM-conformant PACS environments and LIS-integrated digital pathology workflows (e.g., via HL7 v2.5 or ASTM E1703 interfaces). All optional electronic accessories log operational timestamps and usage metrics locally; audit trails are exportable as CSV for GLP/GMP-aligned documentation per FDA 21 CFR Part 11 requirements when paired with validated third-party laboratory information systems.

Applications

• Clinical gross dissection in accredited hospital pathology labs performing >500 surgical cases/month.
• Academic histology core facilities supporting teaching, research, and biobanking operations.
• Contract research organizations (CROs) conducting GLP-compliant toxicologic pathology studies requiring traceable specimen handling.
• Veterinary diagnostic laboratories processing diverse species-specific tissues under OIE-recommended biosafety conditions.
• Forensic pathology units requiring durable, decontaminable surfaces compliant with NFPA 45 and CDC Biosafety Level 2 (BSL-2) grossing practices.

FAQ

Is the TH-701 certified for use in CAP-accredited laboratories?
Yes—the mechanical design, material selection, and ventilation performance meet CAP GEN.40550 and COLA G-25 grossing area requirements when installed per manufacturer-specified clearances and ductwork specifications.
Can the exhaust system be ducted to an external scrubber or rooftop fan?
Absolutely. The unit features a standardized 250 mm diameter flanged exhaust port compatible with rigid galvanized steel or PVC ducting; static pressure drop is characterized at 120 Pa @ 1600 m³/h for system design validation.
What maintenance intervals are recommended for the filtration and fluid systems?
Activated carbon pre-filters require replacement every 6 months under continuous use; drain filter baskets should be inspected and cleaned after each shift; PPR and PE piping systems require annual visual integrity assessment per ISO 22851 maintenance protocols.
Does the TH-701 support integration with LIMS or digital pathology platforms?
Via the optional HD imaging module: yes—output signals are natively compatible with common medical-grade video capture cards and DICOM ingestion gateways; no proprietary drivers or cloud dependencies are required.
Are spare parts and technical documentation available internationally?
ZEEDO provides English-language installation manuals, electrical schematics, and CE/ISO declarations of conformity through authorized regional distributors; consumables and wear components (filters, gaskets, faucets) are stocked in EU and US distribution hubs with ≤5 business day lead time.
