Shanghai RightOne LRH-300CL Low-Temperature Incubator & Storage Cabinet

Overview

The Shanghai RightOne LRH-300CL is a dual-function low-temperature incubator and precision storage cabinet engineered for demanding life science applications requiring stable thermal control across an extended range of −40 °C to +65 °C. Unlike standard refrigerated incubators, the LRH-300CL integrates compressor-based active cooling with intelligent microprocessor-driven temperature management to support both cryogenic sample preservation and controlled-temperature biological cultivation. Its design adheres to fundamental principles of thermal dynamics and convective air circulation—utilizing a high-efficiency scroll compressor, eco-friendly R134a/R406a refrigerants, and a proprietary asymmetric airflow duct system that ensures uniform temperature distribution throughout the 300 L stainless-steel chamber. The unit meets baseline operational requirements for GLP-compliant environments and serves as a foundational platform for workflows involving serum stabilization, vaccine cold-chain validation, microbial strain maintenance, and accelerated stability testing per ICH Q1A(R3) guidelines.

Key Features

• Robust structural architecture: Cold-rolled steel exterior with electrostatic epoxy powder coating; mirror-finish 304 stainless-steel interior chamber with radius-corner geometry for seamless cleaning and contamination control.
• Optimized thermal integrity: Double-glazed, low-emissivity inner door with magnetic seal minimizes heat exchange during observation—critical for maintaining setpoint fidelity during frequent access in QC labs.
• Intelligent control system: 5.7-inch LCD touchscreen interface supporting multi-parameter real-time display—including setpoint, actual chamber temperature, elapsed time, and remaining hold duration—with programmable ramp-soak profiles (optional upgrade).
• Resilient power management: Built-in parameter retention memory and auto-recovery function preserves user-defined configurations after unexpected power interruption or controller reset—ensuring continuity in long-duration experiments.
• Mobility and stability integration: Four swivel casters with individual locking brakes enable safe repositioning within shared lab spaces while maintaining vibration-isolated placement on level surfaces.
• Energy-conscious engineering: High-COP compressor pairing with optimized insulation (≥80 mm polyurethane foam, CFC-free) delivers improved kWh/L performance relative to legacy −40 °C cabinets meeting ISO 13732-1 thermal safety benchmarks.

Sample Compatibility & Compliance

The LRH-300CL accommodates a broad spectrum of biospecimens and materials—including cryopreserved cell suspensions, lyophilized reagents, diagnostic calibrators, and thermolabile enzyme preparations—within its fully adjustable shelving system (standard configuration: 3 fixed + up to 23 removable stainless-steel trays). All internal components comply with USP environmental classification prerequisites for non-sterile compounding areas when operated under validated cleanroom-grade air filtration (optional HEPA add-on available). While not intrinsically certified to ISO 13485 or FDA 21 CFR Part 11, the system supports audit-ready documentation through optional RS485/USB data logging interfaces and third-party calibration traceability to NIST-traceable standards. Its temperature uniformity profile (±0.5 °C across full load, per ASTM E742-22 test methodology) qualifies it for routine use in ISO/IEC 17025-accredited laboratories performing method verification per CLSI EP10-A3.

Software & Data Management

Standard firmware includes timestamped event logging for alarm triggers (e.g., door-open duration >30 s, deviation >1.0 °C), temperature excursions, and system startup/shutdown cycles—retained for ≥30 days in non-volatile memory. Optional connectivity modules enable integration with LIMS platforms via Modbus RTU or TCP/IP protocols. The USB/RS485 interface kit (sold separately) permits export of comma-delimited CSV files compatible with JMP, Python pandas, or LabArchives eLN environments. When paired with the optional embedded thermal printer, users generate hard-copy records satisfying ALCOA+ data integrity criteria—including attributable, legible, contemporaneous, original, and accurate metadata—supporting 21 CFR Part 11 readiness when combined with institutional electronic signature policies.

Applications

• Long-term storage of human and animal sera, monoclonal antibodies, and viral vectors at −40 °C to inhibit proteolytic degradation and aggregation kinetics.
• Controlled-temperature cultivation of psychrophilic bacteria (e.g., Pseudomonas fluorescens, Colwellia psychrerythraea) and cold-adapted yeasts for bioprospecting studies.
• Stability assessment of pharmaceutical intermediates under ICH Q5C freeze-thaw cycling protocols.
• Pre-conditioning of polymer-based medical device substrates prior to tensile or adhesion testing per ISO 5832-1.
• Environmental simulation for electronics reliability testing (e.g., MIL-STD-810H, Method 502.7 low-temperature storage).

FAQ

What is the verified temperature uniformity across the full 300 L chamber volume?
Measured per ASTM E742-22 at nine standardized locations under no-load conditions, the unit maintains ≤±0.5 °C deviation from setpoint at both −40 °C and +65 °C extremes.
Can this incubator be validated for GxP-regulated workflows?
Yes—when equipped with optional data logging hardware and operated under documented IQ/OQ/PQ protocols aligned with Annex 15 and WHO TRS 986, it supports qualification for GLP and GMP Annex 11 environments.
Is external humidity control available?
No—this is a temperature-only controlled system; relative humidity is unregulated and will vary passively with ambient lab conditions and door-opening frequency.
What safety certifications does the LRH-300CL carry?
It conforms to GB 4793.1–2019 (China’s equivalent to IEC 61010-1) for laboratory electrical equipment safety; CE marking is pending upon EU Authorized Representative engagement.
How often does the compressor require scheduled maintenance?
Under continuous operation at −40 °C, manufacturer-recommended oil inspection and filter replacement intervals are every 18 months or 10,000 operating hours—whichever occurs first—using OEM-specified mineral oil and desiccant filters.
