JIAYUAN RS-12 Stainless Steel Dry-Housing Laboratory Rabbit Cage

Overview

The JIAYUAN RS-12 Stainless Steel Dry-Housing Laboratory Rabbit Cage is a purpose-engineered housing system designed for the humane, hygienic, and standardized maintenance of New Zealand White, Dutch Belted, or other medium-sized laboratory rabbits (Oryctolagus cuniculus) in non-GLP and GLP-compliant preclinical research facilities. Unlike flush-type or metabolic cages, the RS-12 implements a dry-housing paradigm—relying on absorbent bedding (e.g., autoclaved wood shavings or paper-based substrates) and scheduled manual cleaning—to minimize water exposure, reduce ambient humidity, and mitigate pododermatitis risk. Its structural architecture follows the geometric and ergonomic principles outlined in ISO 10993-1 (biocompatibility), GB/T 14925–2010 (Laboratory Animal—Environment and Housing), and NIH Guide for the Care and Use of Laboratory Animals (8th Edition). The cage’s open-bottom design with welded wire mesh floor (20 mm × 20 mm aperture, 2.5 mm wire diameter) ensures optimal ventilation, waste separation, and foot support while preventing entrapment. All load-bearing components—including vertical posts, horizontal rails, and door hinges—are fabricated from electropolished AISI 304 stainless steel (EN 1.4301), providing corrosion resistance against disinfectants (e.g., 0.5% sodium hypochlorite, 75% ethanol, peracetic acid) and long-term durability under repeated autoclaving (up to 134 °C, 3 bar).

Key Features

• Modular 3 × 4 configuration supporting twelve (12) individual rabbit enclosures per rack—optimized for space efficiency and workflow scalability in core vivariums.
• Electropolished 304 stainless steel construction with seamless welds and radius-rounded internal corners to eliminate bacterial harborage points and simplify cleaning validation.
• Adjustable-height door latches and reinforced sliding doors with dual-locking mechanism ensure secure containment during transport and routine husbandry.
• Integrated mounting slots compatible with standard IVC (Individually Ventilated Cage) rack interfaces and auxiliary accessories (e.g., feed hoppers, environmental enrichment devices).
• Non-porous, non-shedding surface finish compliant with ISO 14644-1 Class 7 cleanroom requirements when installed in controlled airflow vivarium zones.

Sample Compatibility & Compliance

The RS-12 accommodates rabbits weighing 2.5–5.0 kg, conforming to weight-based floor area requirements stipulated in EU Directive 2010/63/EU (minimum 0.36 m² per adult rabbit) and AAALAC International standards. Each cage provides ≥0.20 m² usable floor area (500 × 400 mm), exceeding the 0.18 m² threshold for single-housed animals under GB/T 14925–2010. Bedding depth is configurable between 2–5 cm to support natural burrowing behavior and thermal regulation. The system is validated for use with common disinfection protocols including vaporized hydrogen peroxide (VHP) decontamination cycles and saturated steam sterilization (121 °C, 20 min). Documentation packages include material traceability certificates (MTRs), surface roughness reports (Ra ≤ 0.8 µm), and third-party biocompatibility test summaries per ISO 10993-5 and -10.

Software & Data Management

While the RS-12 is a passive physical housing unit without embedded electronics, it integrates seamlessly into digital vivarium management ecosystems via standardized rack-level RFID tagging (ISO 15693 compliant) and barcode-labeled cage identifiers. When deployed with JIAYUAN’s optional VivariumLink™ Rack Monitoring Module (sold separately), users can log cleaning timestamps, bedding change records, and animal assignment metadata directly into institutional LIMS or electronic veterinary health record (eVHR) platforms. All hardware identifiers adhere to MIAME (Minimum Information About a Microarray Experiment)-aligned metadata schema to support audit readiness for AAALAC, FDA, or ISO/IEC 17025 assessments.

Applications

• Chronic toxicology studies requiring stable, low-stress housing over 28–90 day durations.
• Vaccine immunogenicity trials where minimized microbial load and consistent environmental parameters are critical.
• Pharmacokinetic/pharmacodynamic (PK/PD) modeling cohorts requiring precise body weight tracking and minimal handling-induced variability.
• Breeding colony management for genetically homogeneous lines—when paired with RS-6 reproduction cages on shared rack infrastructure.
• Educational use in university comparative medicine laboratories adhering to FELASA (Federation of European Laboratory Animal Science Associations) teaching guidelines.

FAQ

Is the RS-12 suitable for regulatory submission studies under OECD TG 407 or USP <1042>?
Yes—the cage design, material certification, and cleaning validation protocols align with OECD Guidance Document No. 116 and USP General Chapter <1042> “Animal Welfare in Pharmaceutical Testing,” provided institutional SOPs define frequency of sanitation, bedding replacement, and environmental monitoring.
Can the RS-12 be autoclaved as a fully assembled unit?
No—only disassembled components (cage panels, doors, feed trays) are rated for full-cycle autoclaving; the rack structure must be cleaned via validated spray-and-wipe or VHP methods.
What is the maximum recommended occupancy per cage?
One adult rabbit (≥2.5 kg); pair-housing is permitted only for compatible breeding pairs under approved IACUC protocols and requires supplemental floor area verification.
Does JIAYUAN provide installation and IQ/OQ documentation?
Yes—factory-authorized commissioning includes Installation Qualification (IQ) templates, Operational Qualification (OQ) test scripts for door integrity and structural load testing (per ASTM E1782-17), and user training modules.
