Overview
The Shanghai RightOne LHS-100CB is an upright, air-cooled temperature and humidity controlled chamber engineered for precise environmental simulation in laboratory and quality assurance settings. It operates on the principle of active thermoelectric and vapor compression refrigeration combined with resistive steam humidification and forced-air convection—enabling stable, repeatable control across a wide operational envelope (−20°C to +80°C; 30–95% RH). Designed for compliance-critical applications—including biobanking, pharmaceutical stability testing, electronic component qualification, and materials aging—the LHS-100CB integrates robust thermal insulation, dual-layer observation doors with low-emissivity glass, and a microprocessor-based PID control architecture. Its chamber volume of 100 L provides sufficient capacity for multi-tier sample staging while maintaining spatial uniformity within defined ISO 17025-aligned tolerances under no-load conditions.
Key Features
- Upright configuration with castor-mounted base (dual-mode: omnidirectional + lockable fixed feet) for flexible lab integration and safe repositioning.
- Interior constructed from electropolished mirror-finish stainless steel (AISI 304), featuring radius-rounded corners and adjustable stainless steel shelving (2 standard / up to 14 positions).
- Environmentally compliant refrigerant system utilizing R134a and R406a blends—meeting international ozone depletion potential (ODP = 0) and global warming potential (GWP) regulatory thresholds.
- High-efficiency air circulation architecture incorporating tangential blower, optimized duct geometry, and baffle-guided airflow—achieving ≤±0.5°C temperature deviation across the working volume (per IEC 60068-3-5).
- Dual-door structure: outer insulated panel + inner tempered glass door with silicone gasket seal—minimizing thermal bridging and enabling real-time visual monitoring without compromising chamber integrity.
- Integrated humidification system comprising stainless steel water reservoir, submerged tubular heating elements, and proprietary vapor dispersion manifold—ensuring rapid RH recovery and ≤±3% RH stability (measured per ASTM E145 Annex A3).
Sample Compatibility & Compliance
The LHS-100CB accommodates a broad range of sample formats—including cryovials, Petri dishes, PCR plates, PCB assemblies, polymer specimens, and sealed biological containers—without risk of condensation ingress or mechanical interference. Its internal dimensions (450 × 380 × 590 mm) support standardized ISO/IEC 17025-compliant placement protocols. The unit conforms to electromagnetic compatibility standards (EN 61326-1), safety requirements (EN 61010-1), and environmental test methodology guidelines (IEC 60068-2 series). While not certified to FDA 21 CFR Part 11 out-of-the-box, its optional RS485/USB interface supports third-party data acquisition systems configured for audit-trail-enabled GLP/GMP workflows.
Software & Data Management
The embedded 5.7-inch TFT-LCD controller implements a programmable logic sequence engine supporting up to 99 cycles, each with 30 configurable segments (max 99 h 59 min per segment). All setpoints, deviations, alarm states, and runtime logs are timestamped and stored locally. Optional connectivity modules (RS485/USB + dedicated PC software) enable remote parameter adjustment, real-time graphing, CSV export, and automated report generation. When paired with validated external data loggers, the system meets traceability requirements for ISO/IEC 17025 accreditation and long-term stability studies referenced in ICH Q1A(R2) and USP .
Applications
- Biological specimen storage: plasma, serum, vaccines, and primary cell lines requiring sustained sub-zero preservation at defined humidity.
- Accelerated stability testing per ICH guidelines for pharmaceutical intermediates, excipients, and finished dosage forms.
- Environmental stress screening of printed circuit boards, sensors, and optoelectronic components under combined thermal-hygrometric load.
- Material science research involving hygroscopic polymers, composites, and battery electrolytes subjected to cyclic humidity exposure.
- Calibration verification of portable hygrometers and thermometers against NIST-traceable reference standards.
FAQ
What is the minimum operating temperature of the LHS-100CB?
The unit achieves and maintains −20°C continuously under no-load conditions at ambient 20°C/50% RH.
Does the chamber support programmable ramp-and-soak profiles?
Yes—its microcontroller supports multi-segment cycling with independent temperature/humidity ramp rates, dwell times, and transition logic.
Is the humidity system self-draining or manual-refill?
It features an internal 3.2 L stainless steel reservoir requiring periodic manual refilling; no condensate pump or external water line is needed.
Can external sensors be connected for independent validation?
Yes—optional 25 mm or 50 mm diameter test ports (with silicone grommets) allow insertion of calibrated reference probes during IQ/OQ/PQ protocols.
What power supply specifications are required?
The LHS-100CB operates on single-phase AC 220 V ±10%, 50 Hz, with a rated input power of 3000 W and requires a dedicated 16 A circuit breaker.
