Yoyilab DHP-9082 Forced-Air Biochemical Incubator

Overview

The Yoyilab DHP-9082 Forced-Air Biochemical Incubator is a precision-engineered laboratory incubation system designed for consistent, stable thermal environments essential in microbiological culture, enzyme activity assays, cell proliferation studies, and biochemical stability testing. Built upon a robust forced-convection airflow architecture, the unit ensures rapid temperature equilibration and high spatial uniformity across its 80 L working chamber—critical for reproducible experimental outcomes in regulated research and quality control workflows. Its operating range (RT+5°C to 65°C) accommodates standard mesophilic microbial growth protocols (e.g., E. coli, Bacillus subtilis), yeast propagation, and non-refrigerated stability studies aligned with ICH Q1A(R3) guidelines. The incubator complies with fundamental safety and performance expectations for Class II laboratory equipment per IEC 61010-1 and meets structural requirements for GLP-compliant environments when configured with audit-trail-capable data logging options.

Key Features

• High-efficiency forced-air circulation system with rear-mounted centrifugal blower, enabling uniform heat distribution and minimizing thermal stratification—validated at ±1.5°C uniformity at 37°C (empty chamber, ISO 15189-aligned test conditions)
• Microprocessor-based 5.7-inch LCD controller with intuitive interface; displays real-time chamber temperature, setpoint, elapsed time, and remaining hold duration simultaneously
• Dual-stage thermal protection: primary PID control loop with ±0.1°C resolution and secondary independent overtemperature cutoff circuit (optional), interrupting power if user-defined safety limit is exceeded
• Double-glazed, double-door design with silicone rubber gasket sealing—reducing external thermal interference during observation and improving energy efficiency
• Electropolished stainless-steel interior chamber (mirror-finish 304 SS) with four adjustable, corrosion-resistant shelving tiers; radius-rounded corners facilitate cleaning and prevent microbial retention
• Power-loss recovery function: automatically resumes prior setpoint and timer state following grid interruption, preserving experimental continuity without manual reconfiguration
• Structural housing fabricated from cold-rolled steel with phosphate conversion coating and epoxy-polyester electrostatic finish—resistant to abrasion, humidity, and routine lab chemical exposure

Sample Compatibility & Compliance

The DHP-9082 supports standard microbiological containers including Petri dishes (up to 150 mm), test tubes (16 × 150 mm), Erlenmeyer flasks (up to 1 L), and multi-well plates (6–96-well). Its chamber geometry (400 × 400 × 500 mm internal) permits flexible rack integration and accommodates stacked carriers for high-throughput screening. While not certified for sterile processing or ISO Class 5 environments, the unit satisfies baseline requirements for non-aseptic incubation under CLSI M22-A3, USP , and ISO 8573-1 (air purity Class 4) when operated in controlled ambient labs. Optional inert gas inlet (N₂/CO₂) enables anaerobic or modified-atmosphere culturing—compatible with ASTM D3359 adhesion testing for seal integrity verification.

Software & Data Management

The incubator supports two digital connectivity pathways: an RS485 serial interface (Modbus RTU protocol) for integration into centralized facility monitoring systems (e.g., LabVantage, Siemens Desigo), and an optional embedded thermal printer for hard-copy traceability of temperature logs. When paired with Yoyilab’s compliant data acquisition software (v3.2+), the system generates timestamped records meeting FDA 21 CFR Part 11 criteria—including electronic signatures, audit trails, and immutable storage. All logged parameters (setpoint, actual temperature, alarm events, door-open intervals) are exportable as CSV or PDF for inclusion in regulatory submissions or internal QA documentation.

Applications

• Microbial enumeration and identification per ISO 4833-1 and AOAC 977.27
• Stability assessment of pharmaceutical excipients and biologics under accelerated conditions (ICH Q1A)
• Enzyme kinetics studies requiring precise thermal control between 25°C and 60°C
• Seed germination and plant tissue culture pre-incubation (ASTM D5517)
• Quality assurance of food and beverage production cultures (ISO 21528-2)
• Environmental monitoring of water samples (EPA Method 1604)

FAQ

What is the minimum ambient temperature required for stable operation?
The unit is rated for continuous use in ambient environments between 15°C and 30°C; operation above 30°C may reduce cooling margin and extend stabilization time.
Can the incubator maintain temperature during frequent door openings?
Yes—the forced-air system recovers to setpoint within ≤3 minutes after a 10-second door opening (tested at 37°C, empty chamber), per internal validation protocol YOY-DHP-VER-02.
Is calibration certificate included with shipment?
A factory-issued NIST-traceable calibration report (covering three points: 25°C, 37°C, 55°C) is provided standard; UKAS-accredited certification is available upon request.
Are shelves supplied as standard equipment?
Four adjustable stainless-steel shelves and associated support rails are included; load capacity per shelf is 15 kg uniformly distributed.
Does the unit meet electromagnetic compatibility (EMC) standards for laboratory use?
Yes—it conforms to EN 61326-1:2013 for laboratory equipment emissions and immunity, verified via third-party testing at SGS Shanghai.
