Overview
The Jiayuan PG-5/5-Layer Universal Rodent Flat-Rack System is an engineered stainless steel housing support structure designed for standardized, space-efficient, and hygienic management of both mouse and rat cages in preclinical research, GLP-compliant toxicology studies, and SPF animal facilities. Unlike modular stackable cage racks or vertical tower systems, this flat-rack architecture employs a horizontal, open-frame design optimized for manual handling, visual inspection, and integration with automated cage-washing lines. Its structural integrity derives from welded AISI 304 stainless steel tubing—resistant to corrosion, autoclaving, and repeated chemical disinfection (e.g., peracetic acid, sodium hypochlorite, and vaporized hydrogen peroxide). The rack’s 5-tier configuration accommodates industry-standard cage footprints—including M-1 (290 × 180 mm), M-5 (475 × 350 mm), CP-4 (466 × 314 mm), and R-1 (460 × 300 mm)—enabling flexible deployment across mixed-species housing protocols without reconfiguration.
Key Features
- Five-tier horizontal platform design with uniform 280 mm vertical spacing between tiers—optimized for ergonomic access and unobstructed airflow under static and forced-ventilation cage systems.
- Four dual-wheel casters (two with locking brakes) ensure stable mobility on smooth epoxy or vinyl flooring while maintaining alignment during transport within vivarium corridors or cage-wash areas.
- Smooth, non-porous 304 stainless steel surfaces meet ASTM A967 passivation requirements and support routine decontamination cycles compliant with NIH Guide for the Care and Use of Laboratory Animals Appendix A.
- No welded seams at load-bearing junctions; all structural joints are fully TIG-welded and ground flush to eliminate debris traps and facilitate cleaning validation per ISO 14644-1 Class 7–8 environmental standards.
- Modular footprint (1450 mm L × 400 mm D × 1500 mm H) enables side-by-side placement with standard IVC units and compatibility with most institutional cage storage carts and lift tables.
Sample Compatibility & Compliance
The PG-5/5-Layer rack supports all major commercially available rodent caging formats, including ventilated (IVC), static, and individually ventilated cage systems requiring flat-bottom mounting. It is validated for use with cages conforming to ASTM E1752–22 (Standard Specification for Laboratory Animal Caging) and EU Directive 2010/63/EU Annex III housing criteria. Rack loading adheres to maximum distributed weight limits of 45 kg per tier when used with polycarbonate or polysulfone cages filled to nominal capacity. Surface finish meets Ra ≤ 0.8 µm specification for microbial retention control, supporting facility-wide environmental monitoring programs required under AAALAC International accreditation and FDA GLP (21 CFR Part 58) facility audits.
Software & Data Management
While the PG-5/5-Layer rack itself is a passive mechanical infrastructure component, its dimensional consistency and barcode-ready labeling zones (top-tier front crossbar) integrate seamlessly with institutional animal management software platforms—including LabVantage LIMS, Provantis, and Scion RDS. Each rack can be assigned a unique asset ID and mapped to room-level HVAC zoning data, enabling real-time tracking of cage turnover rates, maintenance history, and sterilization cycle logs. Optional RFID tag mounts (not included) are available for integration with automated inventory reconciliation systems used in high-throughput breeding colonies.
Applications
This rack system is routinely deployed in:
- SPF mouse and rat breeding colonies where frequent cage changes and health monitoring necessitate rapid visual access and minimal handling stress.
- Toxicology and pharmacokinetic study satellite facilities requiring traceable cage positioning and batch-level environmental logging.
- Vivarium renovation projects replacing outdated wire-mesh racks with corrosion-resistant, wash-down-compatible alternatives.
- Teaching laboratories conducting longitudinal behavioral assays where consistent cage orientation and lighting exposure across tiers are critical.
- Contract research organizations (CROs) operating multi-client study rooms with variable cage size requirements across concurrent protocols.
FAQ
Is the PG-5/5-Layer rack compatible with IVC systems requiring power or air duct connections?
Yes—its open-tubular frame allows unimpeded routing of air supply hoses and electrical conduits beneath each tier. No integrated power or filtration is provided; it serves strictly as a mechanical support platform.
Can this rack be autoclaved or sterilized using VHP?
The full assembly is not autoclavable due to caster heat limitations, but individual rack tiers (without casters) withstand steam sterilization at 121°C for 20 min. VHP (vaporized hydrogen peroxide) treatment is fully supported at standard 60% RH and 590 ppm concentration.
Does the rack include cage retention hardware such as clips or straps?
No—retention accessories are sold separately and selected based on cage manufacturer specifications (e.g., Tecniplast, Allentown, or NKP cages). Standard M6 threaded inserts are located at each corner of every tier for optional accessory mounting.
What is the recommended cleaning protocol between study cohorts?
Rinse with potable water, followed by alkaline detergent soak (pH 11.5, 60°C, 15 min), mechanical scrub, acid rinse (pH 3.5), and final hot-air drying. Validation via ATP bioluminescence assay is advised per institutional SOP.
