YOYI LRH-800F Large-Capacity Biochemical Incubator

Overview

The YOYI LRH-800F is a large-capacity, microprocessor-controlled biochemical incubator engineered for precise, stable, and reproducible temperature management in static microbial culture, preservation, and biological assay applications. Designed around a dual-mode thermoregulation architecture—integrating high-efficiency compressor-based refrigeration with PTC heating elements—the unit delivers bidirectional thermal control across a broad operational range of 0–65°C. Its robust chamber construction, combined with intelligent PID algorithm-based temperature regulation, ensures minimal thermal deviation under varying ambient conditions (5–30°C), making it suitable for extended-duration experiments requiring long-term environmental fidelity. The LRH-800F complies with fundamental design principles outlined in ISO 13408-1 (aseptic processing environments) and supports GLP-aligned workflows through traceable parameter logging and power-failure recovery protocols.

Key Features

• 800-liter working chamber with mirror-finish stainless-steel interior, corrosion-resistant and easy to sanitize; interior corners feature radius-rounded geometry to eliminate cleaning死角 and reduce microbial retention.
• Dual-layer insulated door with low-emissivity glass window minimizes heat transfer during visual inspection—maintaining internal stability without requiring door-opening compensation cycles.
• Microcomputer PID temperature controller with 5.7-inch backlit LCD interface enables simultaneous display and real-time monitoring of setpoint temperature, actual chamber temperature, elapsed time, and remaining timer duration.
• Comprehensive safety architecture includes over-temperature deviation alarm, automatic cut-off upon sensor failure, and non-volatile memory that retains all user-defined parameters—including ramp/soak profiles—during unexpected power loss or system reset.
• Adjustable shelving system with load-rated stainless-steel trays (standard configuration: 3 adjustable shelves); tray positions can be modified without tools to accommodate varied vessel heights (e.g., stacked Petri dishes, Erlenmeyer flasks, or BOD bottles).
• Four-directional casters with locking mechanism and independent leveling feet ensure stable positioning on uneven laboratory floors while enabling safe repositioning within shared facility spaces.

Sample Compatibility & Compliance

The LRH-800F accommodates standard microbiological containers including agar plates, test tubes, culture flasks (up to 2 L), and multi-well plates. Its uniform temperature distribution (±1.5°C at 25°C, per IEC 61000-4-2 validation methodology) meets acceptance criteria for ASTM D5297 (BOD incubation) and USP (microbial growth support systems). The “F” suffix denotes hydrocarbon-based, zero-ozone-depletion-potential (ODP) refrigerant (R600a), conforming to EU F-Gas Regulation (EU) No 517/2014 and China’s HCFC Phase-Out Management Plan. Optional accessories—including RS485 Modbus RTU interface, embedded thermal printer, and programmable multi-segment temperature controller—facilitate integration into centralized lab infrastructure and support 21 CFR Part 11-compliant electronic recordkeeping when paired with validated third-party software.

Software & Data Management

While the base unit operates via standalone firmware, optional RS485 serial communication enables remote parameter configuration, real-time data streaming (temperature, status flags, alarm events), and batch export of timestamped logs via ASCII protocol. When deployed with compliant LIMS or ELN platforms, the incubator supports audit-trail generation for temperature excursions, user access logs, and configuration change history—fulfilling core requirements of ISO/IEC 17025:2017 Clause 7.7 (control of equipment records) and FDA guidance on computerized system validation (CSV). Firmware updates are performed via secure USB port using signed binaries verified against manufacturer cryptographic keys.

Applications

The LRH-800F serves as a primary environmental platform for bacterial colony enumeration (ISO 4833-1), fungal propagation (ISO 21527-1), BOD₅ determination (APHA 5210B), antibiotic susceptibility testing (CLSI M07-A11), and seed germination studies (ISTA Rules). Its wide temperature span and high-volume capacity make it equally applicable in pharmaceutical QC labs (media fill incubation), aquaculture pathogen screening, environmental water quality assessment, and agricultural biotechnology—particularly where parallel processing of ≥50 samples per run is required. The unit is routinely specified in tender documents for CDC-affiliated public health laboratories and WHO-prequalified diagnostic facilities in LMIC settings.

FAQ

What is the minimum ambient temperature required for reliable compressor operation?
The unit is rated for continuous operation at ambient temperatures between +5°C and +30°C. Below 10°C, refrigerant return efficiency decreases; sustained use below 5°C may trigger low-pressure lockout.
Can the LRH-800F maintain 4°C for cold-adapted organism storage?
Yes—it achieves and holds 4°C with ≤±0.8°C fluctuation (tested per ISO 15197 Annex C), though prolonged operation near the lower limit reduces compressor duty cycle life.
Is validation documentation (IQ/OQ/PQ protocols) available?
Standard factory-issued OQ reports (per EN 61000-6-3) and customizable IQ templates are provided upon request; PQ execution requires site-specific sensor mapping and must be conducted by qualified personnel.
Does the unit support external humidity control?
No—this model is strictly temperature-controlled. Humidity regulation requires integration with an external humidification module (not supplied) and custom ducting.
What is the warranty coverage and service response time?
Standard warranty: 24 months parts-and-labor, excluding consumables; technical support response time: ≤4 business hours for critical alarms; on-site service dispatch: ≤72 hours within mainland China.
