Jiayuan M-1/70 Stainless Steel Mouse Caging Rack System

Overview

The Jiayuan M-1/70 Stainless Steel Mouse Caging Rack System is a modular, floor-standing housing solution engineered for standardized rodent husbandry in biomedical research laboratories, preclinical testing facilities, and SPF (Specific Pathogen-Free) animal units. Designed in strict accordance with internationally recognized principles of laboratory animal science—including those outlined in the Guide for the Care and Use of Laboratory Animals (NRC, 2011), AAALAC International standards, and ISO 14644-1 Class 7 cleanroom compatibility—the system integrates structural integrity, corrosion resistance, and operational ergonomics. Constructed entirely from electropolished 304 stainless steel, the rack features a robust T-shaped frame architecture with reinforced cross-bracing to support static loads up to 150 kg per tier. Its open-grid design ensures uniform airflow distribution across all cage levels, facilitating effective ventilation when used with forced-air IVC (Individually Ventilated Cage) systems or passive air exchange configurations. The M-1/70 configuration accommodates exactly 70 standard M-1 mouse cages (290 × 180 × 160 mm), arranged across five horizontal tiers, seven cages per side, enabling high-density yet ethically compliant housing under current EU Directive 2010/63/EU and NIH OLAW guidelines.

Key Features

• Electropolished 304 stainless steel construction for long-term resistance to autoclaving (up to 134°C, 30 min), chemical disinfectants (e.g., 70% ethanol, 1% sodium hypochlorite, peracetic acid), and repeated cage washing cycles
• T-shaped structural frame with adjustable leveling feet and four dual-locking casters (two with brakes) for stable positioning and safe mobility within vivarium corridors
• Standardized mounting interface compatible with Jiayuan M-1 mouse cages (290 × 180 × 160 mm), including integrated cage retention clips and drip tray alignment guides
• Optimized vertical spacing between tiers (300 mm center-to-center) to accommodate cage height, lid clearance, and manual handling without ergonomic strain
• Modular scalability—multiple M-1/70 racks can be aligned side-by-side with interlocking end panels to form continuous caging banks while maintaining required service aisles (≥1200 mm)

Sample Compatibility & Compliance

The M-1/70 rack is validated for use with Jiayuan’s full suite of M-series mouse cages (M-1 through M-6), as well as CP-, CPM-, and PP-series alternatives. All associated cage components—including stainless steel wire mesh lids, polycarbonate or polysulfone cage boxes, and screw-top glass or polypropylene water bottles—are designed to meet ASTM F2149–22 (Standard Specification for Rodent Cages) and ISO 5941–1:2020 (Laboratory animal science — Caging systems). When deployed in conjunction with HEPA-filtered IVC systems, the rack supports compliance with GLP (Good Laboratory Practice) Annex III requirements for environmental monitoring and documentation. Its non-porous surface finish satisfies USP and criteria for cleaning verification, and routine ATP bioluminescence assays confirm ≤100 RLU residual contamination post-sanitization.

Software & Data Management

While the M-1/70 rack itself is a passive mechanical system, it integrates seamlessly into digital vivarium management ecosystems via standardized barcode labeling (ISO/IEC 15420-compliant) on each cage position. Each tier and cage slot is uniquely encoded to interface with LIMS platforms such as Provantis, LabVantage, or custom-built animal tracking modules. Cage-level metadata—including strain, protocol ID, acclimatization date, and scheduled health monitoring—can be logged directly into electronic animal records. Audit trails generated during rack reconfiguration or cage relocation comply with FDA 21 CFR Part 11 requirements when paired with validated e-signature workflows.

Applications

This caging system serves critical functions across multiple preclinical domains: longitudinal toxicity studies requiring consistent housing conditions over 28–90-day dosing regimens; immunology research where microbiological containment must remain uncompromised across repeated cage changes; behavioral phenotyping setups requiring identical environmental parameters across treatment cohorts; and breeding colony management where spatial predictability enhances technician efficiency and minimizes stress-induced variability. Its compact footprint (1450 × 400 × 1500 mm) makes it suitable for retrofitting into existing vivarium infrastructure without major HVAC recalibration.

FAQ

Is the M-1/70 rack compatible with IVC systems from other manufacturers?

Yes—its dimensional tolerances and mounting geometry align with industry-standard IVC interfaces (e.g., Tecniplast Green Line, Allentown A-1000, Thoren Living Systems), provided cage adapters are used per OEM specifications.

What is the maximum recommended load per tier?

Each tier is rated for 30 kg gross load (including cage, bedding, animals, and accessories), verified per EN 1090-1:2018 structural execution standards.

Can the rack be autoclaved?

No—the assembled rack is not autoclavable due to welded joints and caster assemblies; however, all component parts (excluding wheels and brake mechanisms) may be disassembled and sterilized individually using steam or hydrogen peroxide vapor.

Does the system support RFID cage tracking?

Yes—integrated RFID tag mounting points are available on each cage slot bracket; compatible with ISO 18000-6C readers and middleware supporting EPCglobal Gen2 protocols.

Are replacement casters and leveling feet available as spare parts?

Yes—Jiayuan provides certified replacement kits (Part No. JC-M170-CW-SET) with RoHS-compliant materials and traceable calibration documentation.
