Yoyilab DHP-9162 Electric Constant Temperature Incubator

Overview

The Yoyilab DHP-9162 Electric Constant Temperature Incubator is a precision-engineered benchtop incubation system designed for reliable, stable thermal control in microbiological culture, cell propagation, and biochemical storage applications. Utilizing a forced-air convection architecture with optimized airflow distribution, the unit maintains uniform thermal conditions across its 160 L working chamber—critical for reproducible growth kinetics of mammalian cells, bacterial strains (e.g., E. coli, Bacillus subtilis), fungal isolates, and hybridoma cultures. Its operational range spans from ambient +5°C to 65°C, accommodating both mesophilic and thermotolerant organism protocols. The incubator’s core thermal regulation relies on a digital PID controller with real-time feedback from multiple high-stability PT100 sensors, ensuring minimal thermal overshoot and long-term drift stability under continuous operation.

Key Features

• Robust construction: Cold-rolled steel exterior with phosphate conversion coating and electrostatic powder finish; mirror-polished stainless-steel interior chamber with seamless, radius-rounded corners for easy decontamination and reduced microbial retention.
• Dual-door design with magnetic silicone gasket seal: Minimizes heat loss during observation and enhances energy efficiency without compromising internal temperature integrity.
• Intelligent LCD interface: 5.7-inch backlit display showing setpoint, real-time chamber temperature, elapsed time, and timer countdown—all simultaneously visible without menu navigation.
• Comprehensive safety architecture: Independent over-temperature cut-off circuit (optional), automatic power recovery after outage with parameter memory retention, and deviation-based alarm triggering (±2.0°C default threshold).
• Thermal insulation: High-density polyurethane foam (≥40 mm thickness) combined with perimeter-sealed door gaskets ensures low thermal conductivity (<0.025 W/m·K) and extended service life.
• Modular shelf system: Two adjustable stainless-steel shelves included; load capacity per shelf: 15 kg; vertical positioning via pre-drilled support slots at 25 mm intervals.

Sample Compatibility & Compliance

The DHP-9162 accommodates standard culture formats including Petri dishes (up to 150 mm), multi-well plates (6–96-well), Erlenmeyer flasks (up to 2 L), and glass or polycarbonate tissue culture vessels. Its chamber geometry supports stacked configurations while maintaining laminar airflow patterns essential for contamination-sensitive workflows. The unit meets general requirements for ISO 13485–aligned quality systems and is suitable for use in laboratories operating under Good Laboratory Practice (GLP) frameworks. Optional accessories—including an RS485 communication port with timestamped, audit-trail-enabled software and an embedded thermal printer—enable compliance with FDA 21 CFR Part 11 for electronic records and signatures when deployed in regulated biomanufacturing or QC settings.

Software & Data Management

When equipped with the optional RS485 interface and dedicated PC software, the DHP-9162 supports continuous temperature logging at user-defined intervals (1 sec to 60 min), exportable in CSV or PDF format. The software provides configurable alarm notifications (email/SMS via gateway), trend visualization, and secure user access levels (administrator/operator). All logged data include metadata such as operator ID, instrument serial number, calibration status, and environmental timestamps—satisfying traceability demands for ISO/IEC 17025 accreditation. Printer integration enables hard-copy generation of temperature profiles for batch release documentation or internal SOP adherence verification.

Applications

• Mammalian cell line maintenance (HEK293, CHO-K1, HeLa) at 37°C ±0.5°C with CO₂-independent protocols.
• Bacterial enrichment and enumeration (ASTM D5465, ISO 4833-1) under standardized incubation conditions.
• Enzyme activity assays requiring precise thermal staging between 25°C and 60°C.
• Seed germination studies and plant tissue culture under controlled non-humidified conditions.
• Stability testing of diagnostic reagents and pharmaceutical intermediates per ICH Q1A(R2) guidelines.
• Quality control of raw materials in food processing facilities (e.g., aerobic plate counts per ISO 4833-2).

FAQ

What is the minimum ambient temperature required for stable operation?
The incubator is rated for use in environments where ambient temperature remains between 15°C and 30°C and relative humidity does not exceed 80% RH (non-condensing).

Can the unit be validated for IQ/OQ/PQ protocols?
Yes—its digital PID controller, dual-sensor redundancy (working + safety), and RS485 data output support full qualification using industry-standard templates (e.g., ASTM E2500, EU Annex 15). Calibration certificates for PT100 sensors are available upon request.

Is inert gas purging supported?
An optional inert gas inlet port (with integrated flowmeter and needle valve) is available for nitrogen or argon blanketing to suppress oxidative degradation during anaerobic culture or sensitive compound storage.

How often should the unit be recalibrated?
Annual calibration against NIST-traceable reference standards is recommended; the built-in sensor offset adjustment function allows field correction without disassembly.

Are replacement shelves and gaskets available as spare parts?
Yes—stainless-steel shelves (part no. DHP-SH-500), door gaskets (DHP-GSK-605), and heating elements (DHP-HEAT-550W) are stocked and shipped globally within 5 business days.
