Yoyilab LRH-100F Biochemical Incubator

Overview

The Yoyilab LRH-100F Biochemical Incubator is a precision-engineered, forced-air convection incubator designed for stable, reproducible temperature control across a broad operational range of 0–65 °C. It employs dual-mode thermal regulation—integrated compressor-based refrigeration and resistive heating—to maintain precise setpoints under both ambient-cooling and elevated-temperature conditions. This bidirectional thermal architecture ensures consistent environmental conditions required for microbial cultivation (e.g., bacteria, fungi, yeasts), BOD (Biochemical Oxygen Demand) testing per ISO 5815-1 and ASTM D5210, seed germination studies, plant tissue culture, and long-term sample preservation in life science, environmental monitoring, pharmaceutical quality control, and agricultural research laboratories. Its chamber design complies with fundamental ergonomic and hygienic principles for laboratory incubation: mirror-finish stainless-steel interior, rounded internal corners, adjustable shelving, and double-glazed insulated door with low-thermal-loss viewing window.

Key Features

• Microprocessor-controlled PID temperature regulation with 0.1 °C resolution and real-time deviation compensation
• Robust compressor-based cooling system using ozone-safe, non-CFC refrigerant (R134a or equivalent)
• Forced-air convection via rear-mounted centrifugal fan ensures uniform airflow distribution and minimizes thermal stratification
• 5.7-inch backlit LCD interface supporting multi-parameter display: setpoint, actual chamber temperature, elapsed/remaining time, and alarm status
• Programmable timer (1–9999 minutes) with auto-start and end-cycle notification
• Power-failure recovery function retaining user-defined parameters and resuming operation upon power restoration
• Dual-level over-temperature protection: primary PID control loop + independent mechanical safety cutoff
• Structural integrity: cold-rolled steel outer casing with electrostatic epoxy coating; seamless stainless-steel inner chamber (AISI 304 grade)
• Mobile base with four swivel casters (two lockable) and leveling feet for flexible placement and vibration isolation

Sample Compatibility & Compliance

The LRH-100F accommodates standard microbiological vessels—including Petri dishes, test tubes, flasks, and multi-well plates—on three adjustable stainless-steel shelves (standard configuration). Its ±1.5 °C temperature uniformity (measured at 25 °C per IEC 61000-4-3 and ISO 15195 calibration guidelines) supports GLP-compliant workflows in regulated environments. While not inherently 21 CFR Part 11–compliant out-of-the-box, optional RS485 communication interface enables integration with validated LIMS or ELN systems when paired with audit-trail-enabled software. The unit meets CE electromagnetic compatibility (EMC) requirements and conforms to GB/T 17288–2021 (Chinese national standard for biochemical incubators), aligning with core functional expectations of ISO/IEC 17025-accredited laboratories performing routine biological incubation.

Software & Data Management

The embedded firmware supports local data logging of temperature profiles (time-stamped, with configurable sampling intervals) stored in non-volatile memory. Optional accessories expand connectivity and traceability: an RS485 serial interface (with Modbus RTU protocol support) allows remote monitoring and parameter adjustment via PC-based software; an embedded thermal printer provides hard-copy records for QA documentation; and a multi-segment programmable controller enables complex temperature ramp-hold cycles for developmental biology or accelerated stability studies. All logged data can be exported in CSV format for post-analysis in Excel or statistical packages such as JMP or Minitab—facilitating adherence to internal SOPs and external regulatory review.

Applications

• BOD5 determination in wastewater and surface water analysis (aligned with APHA Standard Methods 5210B and ISO 5815-1)
• Cultivation and maintenance of bacterial cultures (e.g., E. coli, Staphylococcus aureus) and filamentous fungi under defined aerobic conditions
• Seed viability testing and controlled germination trials in agronomy and forestry research
• Storage and conditioning of clinical specimens prior to microbiological assay (CLSI M22-A3 compliant handling)
• Incubation of enzyme-linked immunosorbent assay (ELISA) plates during antigen–antibody binding steps
• Long-term stabilization of reference standards and working stocks in QC/QA labs

FAQ

What is the minimum operating temperature, and is sub-ambient cooling guaranteed?
The LRH-100F achieves stable operation down to 0 °C under standard ambient conditions (≤30 °C, ≤60% RH); performance below 5 °C may vary depending on room temperature and door-opening frequency.
Can this incubator be used for CO₂-sensitive applications?
No—it lacks CO₂ concentration control or humidification; it is strictly a temperature-regulated dry-air incubator.
Is calibration certificate included with shipment?
A factory calibration report (traceable to NIM China) is provided; full ISO/IEC 17025 calibration with uncertainty budget requires third-party service.
What safety certifications does the unit carry?
It complies with GB 4793.1–2019 (Safety Requirements for Electrical Equipment for Measurement, Control, and Laboratory Use) and meets EMC Class B limits per GB/T 18268.1.
Are custom chamber configurations available?
Yes—Yoyilab offers OEM modifications including larger volumes (up to 1000 L), additional access ports (25 mm or 50 mm), and specialized shelving layouts upon request.
