Hanuo HD200 Intelligent Multi-Zone Dry Block Incubator

Overview

The Hanuo HD200 Intelligent Multi-Zone Dry Block Incubator is an engineered solution for high-throughput, precision thermal incubation in molecular biology, clinical diagnostics, and quality control laboratories. Unlike traditional water baths, it employs a high-purity aluminum heating block architecture—offering rapid thermal response, zero risk of contamination, and elimination of evaporation-related variability. Its core operating principle relies on conductive heat transfer through precisely machined, thermally optimized aluminum blocks, enabling stable, uniform temperature distribution across multiple independently controlled zones. Designed for routine applications such as enzyme reactions, serum coagulation, DNA denaturation prior to PCR, and sample pre-incubation for electrophoresis, the HD200 supports GLP-aligned workflows where traceable, reproducible thermal conditions are mandatory. The device operates within a validated ambient-to-110 °C range, with certified accuracy of ±0.3 °C at 37 °C—a performance benchmark aligned with ISO/IEC 17025 calibration requirements for thermal instrumentation used in accredited testing environments.

Key Features

• Four Independent Thermal Zones (A–D): Each zone features dedicated temperature control, real-time monitoring, and fully programmable countdown timers—enabling simultaneous incubation of samples requiring different durations or thermal profiles without cross-interference.
• Modular Flexibility: Supports 16 standardized interchangeable aluminum blocks (including 0.2 mL, 0.5 mL, 1.5 mL, 2.0 mL microcentrifuge tubes, and diameters from 6 mm to 40 mm), with custom block design available upon request for non-standard vessel geometries.
• Integrated Blue Transparent Acrylic Lid: Provides physical containment during high-temperature operation, mitigating aerosol generation, tube ejection, and cross-contamination risks—critical for biosafety Level 2 (BSL-2) compliant workflows.
• Intelligent Operational Logic: Includes auto-preheat mode, power-loss recovery with state retention, and boot-up auto-run functionality—ensuring protocol continuity and reducing manual intervention in unattended overnight runs.
• Dual-Layer Thermal Protection: Hardware-based thermal cutoff fuse (250 V, 3 A) combined with software-monitored overtemperature shutdown ensures compliance with IEC 61010-1 safety standards for laboratory electrical equipment.
• Calibration-Ready Architecture: Factory-traceable temperature calibration at 37 °C; users may perform field verification using NIST-traceable reference probes, with built-in offset adjustment capability for long-term drift compensation.

Sample Compatibility & Compliance

The HD200 accommodates a broad spectrum of sample containers—including standard microcentrifuge tubes (0.2–2.0 mL), PCR strips, vials, and custom reaction vessels—via its modular block system. All aluminum blocks undergo surface passivation to prevent metal ion leaching, ensuring compatibility with sensitive enzymatic assays and nucleic acid workflows. The instrument meets electromagnetic compatibility (EMC) requirements per EN 61326-1 and safety specifications per EN 61010-1. While not FDA-cleared as a medical device, its operational parameters and documentation support validation under ISO 13485 quality management systems for in vitro diagnostic (IVD) manufacturing environments. Data integrity features—including timestamped event logging and non-volatile memory retention—facilitate alignment with FDA 21 CFR Part 11 expectations when integrated into validated laboratory information management systems (LIMS).

Software & Data Management

The HD200 utilizes embedded firmware with a high-contrast LED interface displaying real-time zone temperatures, remaining time, setpoints, and system status codes. Though it does not include PC connectivity or proprietary software, all operational parameters—including timer values, temperature setpoints, and alarm history—are stored in non-volatile memory with battery-backed retention. Event logs record power interruptions, overtemperature events, lid-open occurrences, and calibration adjustments—providing auditable evidence for internal QA reviews and external regulatory inspections. For laboratories implementing electronic lab notebooks (ELN), the device’s deterministic behavior and consistent thermal output enable reliable integration into automated data capture protocols via external environmental monitoring systems.

Applications

• Pre-heating reagents and master mixes prior to PCR setup
• Serum coagulation assays in clinical chemistry workflows
• Enzyme kinetic studies requiring precise, multi-step thermal conditioning
• Cell lysis optimization and protein denaturation protocols
• Stabilization of temperature-sensitive standards and controls in QC labs
• Incubation of bacterial transformation reactions with staggered timing requirements
• Thermal equilibration of samples before HPLC or mass spectrometry injection

FAQ

What is the maximum number of 1.5 mL tubes supported per zone?
Each zone accommodates up to 24 × 1.5 mL tubes using Block #15; with optional high-density configuration, total capacity reaches 96 wells when using 0.2 mL-compatible blocks across all four zones.

Does the HD200 support external temperature probe input for validation?
No—the unit does not feature analog or digital probe input ports. Validation must be performed using external calibrated reference thermometers placed directly in block wells per ISO/IEC 17025 Annex A.3 guidelines.

Can the device maintain temperature stability during frequent lid opening?
The aluminum block’s thermal mass and PID-controlled heating algorithm minimize transient fluctuations; however, repeated lid actuation will extend stabilization time. For critical applications, use the lid sensor interlock (if enabled) to pause timers until closure is confirmed.

Is firmware upgrade capability available?
Firmware updates are performed exclusively by authorized Hanuo service centers using proprietary diagnostic tools; no user-accessible update interface is provided.

What maintenance is required for long-term accuracy?
Annual verification against NIST-traceable standards is recommended. Clean blocks with isopropyl alcohol and lint-free wipes; avoid abrasive cleaners or immersion. Inspect thermal gasket integrity and lid alignment biannually.
