Jiayuan PP-3/70 Stainless Steel Mouse Caging Rack System

Overview

The Jiayuan PP-3/70 Stainless Steel Mouse Caging Rack System is an engineered infrastructure solution designed for standardized rodent housing in academic research laboratories, preclinical testing facilities, and GLP-compliant animal study units. Constructed entirely from electropolished 304 stainless steel, the rack meets stringent requirements for corrosion resistance, cleanability, and structural integrity under repeated autoclaving and chemical disinfection cycles. Its T-type configuration supports dual-sided cage mounting, enabling efficient use of floor space while maintaining unobstructed access to all cage levels. The system adheres to internationally recognized housing guidelines—including those outlined in the Guide for the Care and Use of Laboratory Animals (NRC, 2011) and EU Directive 2010/63/EU—by ensuring adequate ventilation, thermal stability, and ergonomic servicing height (1500 mm total height with lowest tier positioned at 300 mm above floor level). Unlike modular plastic or powder-coated alternatives, this rack provides long-term dimensional stability under load and resists warping during high-humidity or high-pressure washing protocols typical in SPF (Specific Pathogen-Free) barrier facilities.

Key Features

• Electropolished 304 stainless steel frame and support rails for optimal corrosion resistance and surface smoothness (Ra ≤ 0.8 µm), minimizing microbial retention.
• T-type structural design with reinforced cross-bracing ensures static load capacity ≥ 120 kg per tier, accommodating standard polycarbonate or polysulfone cages with bedding, water bottles, and feeders.
• Standardized 7-cage-per-tier layout (5 tiers × 2 sides = 70 total positions) aligns with IVC (Individually Ventilated Cage) system compatibility, including common cage footprints such as 318 × 202 × 135 mm (PP-3) and 294 × 190 × 125 mm (CP-5).
• Integrated drip tray channels along each tier direct condensate and wash water toward rear drainage ports, preventing cross-contamination between levels.
• Modular anchoring points allow secure wall-mounting or floor-bolting in accordance with seismic safety standards (IBC 2021, Section 1613) for high-risk geographic zones.
• Non-porous, weld-free construction eliminates crevices where biofilm formation may occur—validated through ISO 14644-1 Class 5 cleanroom-compatible cleaning validation protocols.

Sample Compatibility & Compliance

The PP-3/70 rack accommodates a broad range of commercially available mouse and rat cages—including ventilated, static, and transport variants—without modification. Compatible cage types include PP-series (e.g., PP-3, PP-4), CP-series (e.g., CP-2, CP-5), and M-series (e.g., M-1, M-5) housings, all conforming to ASTM F2149–22 (Standard Specification for Rodent Cages). The rack’s open architecture supports integration with centralized IVC exhaust manifolds and HEPA-filtered supply ducts. It satisfies institutional animal care and use committee (IACUC) requirements for environmental enrichment compliance when used with nesting material, shelters, and running wheels mounted via standardized cage clips. All materials comply with USP Class VI biocompatibility testing and are free of phthalates, BPA, and heavy metals per RoHS Directive 2011/65/EU.

Software & Data Management

While the PP-3/70 is a passive mechanical system, its standardized dimensions and mounting interface enable seamless integration with digital animal facility management platforms. Barcode- or RFID-tagged cage identifiers (e.g., compliant with ISO/IEC 18000-6C) can be affixed to designated rail zones for automated inventory tracking via mobile scanners. Rack-level metadata—including location, maintenance history, and sanitation logs—can be synchronized with LIMS systems supporting HL7 v2.5 or FHIR R4 standards. Audit trails for cleaning validation (e.g., ATP bioluminescence readings, temperature logs from autoclave cycles) are exportable in CSV or PDF formats compatible with FDA 21 CFR Part 11–compliant electronic records systems.

Applications

This caging rack is routinely deployed in:

• SPF rodent breeding colonies requiring frequent sanitization and barrier integrity verification;
• Pharmacokinetic and toxicology studies where consistent microenvironmental control across 70+ animals is critical for data reproducibility;
• Genetically engineered mouse model (GEMM) repositories demanding traceable cage lineage and minimal cross-exposure risk;
• Contract research organizations (CROs) operating under OECD GLP Principles, where rack-level calibration certificates and material traceability documentation are mandated;
• University core facilities supporting multi-investigator access with shared cage scheduling via integrated calendar APIs.

FAQ

Is the PP-3/70 rack compatible with IVC systems from major vendors (e.g., Tecniplast, Allentown, Lab Products)?

Yes—the rack’s tier spacing (300 mm center-to-center vertical clearance) and rail geometry match standard IVC manifold coupling interfaces per ISO 22716 Annex B specifications.

Can the rack be sterilized using vaporized hydrogen peroxide (VHP)?

Yes—electropolished 304 stainless steel demonstrates full compatibility with VHP cycles up to 1000 ppm exposure; no surface degradation or chloride-induced pitting has been observed after 200+ cycles.

Does the manufacturer provide installation certification or validation documentation?

Jiayuan supplies Factory Acceptance Test (FAT) reports including dimensional inspection records, material mill certificates (ASTM A240), and weld integrity verification per ASME BPVC Section IX. Site-specific IQ/OQ documentation templates are available upon request.

What is the recommended maintenance interval for structural integrity verification?

Annual visual inspection per ISO 13482:2014 Annex D is advised, focusing on rail deformation, fastener torque retention (≥ 12 N·m for M6 stainless bolts), and drip channel continuity.

Are replacement parts (e.g., tier rails, leveling feet, drip trays) available separately?

Yes—all components are serialized and stocked in Beijing distribution centers; lead time for spare parts is typically 5–7 business days ex-warehouse.
