Hanuo HD200 Quad-Zone Dry Block Incubator

Overview

The Hanuo HD200 Quad-Zone Dry Block Incubator is a microprocessor-controlled, high-precision thermal management system engineered for reproducible, scalable sample incubation in molecular biology, clinical diagnostics, and quality control laboratories. Unlike water baths, it employs solid-state conduction via high-purity aluminum heating blocks—eliminating evaporation, contamination risk, and maintenance overhead while delivering superior thermal stability and spatial uniformity. Its core architecture supports simultaneous operation of four independently controlled temperature zones, each with dedicated timing, real-time monitoring, and visual status indication—making it especially suited for multi-step protocols requiring staggered incubation (e.g., enzyme digestion followed by ligation, sequential PCR setup, or parallel serum coagulation assays). The unit operates across a broad range of 0–110 °C, with certified accuracy of ±0.3 °C at 37 °C and uniformity within ±0.2 °C across the block surface under steady-state conditions.

Key Features

• Four Independent Thermal Zones: Each zone (A–D) features discrete timer control (1 min to 99 h 59 min or continuous mode), individual LED status indicators, and programmable setpoints—enabling concurrent incubation of samples with differing time/temperature requirements.
• High-Integrity Aluminum Blocks: Precision-machined, anodized aluminum modules ensure rapid heat transfer, minimal thermal lag, and long-term dimensional stability; factory-calibrated for traceable performance at critical setpoints (e.g., 37 °C, 65 °C, 95 °C).
• Integrated Safety Architecture: Dual-layer overtemperature protection—comprising both firmware-based thermal cutoff and redundant hardware limiter—meets IEC 61010-1 safety requirements for laboratory equipment.
• Intelligent Operational Logic: Supports auto-preheat, power-fail recovery (resumes prior settings upon restoration), and boot-up auto-run—reducing manual intervention and supporting unattended overnight workflows.
• Optimized Sample Protection: Removable transparent blue acrylic lid minimizes aerosol dispersion and prevents tube ejection during exothermic reactions or rapid thermal expansion—critical for handling volatile reagents or high-concentration DNA preparations.
• User-Centric Interface: Backlit LCD displays real-time temperature, elapsed time, remaining time, and active zone status; intuitive navigation enables parameter adjustment without menu nesting.

Sample Compatibility & Compliance

The HD200 accommodates a wide array of standard and custom tube formats via interchangeable aluminum blocks—including 0.2 mL PCR strips (96-well), 1.5 mL and 2.0 mL centrifuge tubes, microcentrifuge tubes (0.2–2.0 mL), and specialized vessels up to 40 mm diameter. All blocks are designed to ISO 8573-1-compliant cleanroom tolerances and undergo post-machining stress-relief annealing to prevent warping. The system supports GLP/GMP-aligned documentation practices: temperature calibration logs can be manually recorded per zone, and its stable thermal profile meets ASTM E2252-02 (Standard Practice for Calibration of Laboratory Thermometers) and ISO/IEC 17025 traceability prerequisites when used with NIST-traceable reference thermometers. While not FDA 21 CFR Part 11–validated out-of-the-box, its deterministic behavior, non-volatile timer memory, and immutable operational logic facilitate internal validation for regulated QC environments.

Software & Data Management

The HD200 operates as a standalone instrument with no external software dependency. All configuration, execution, and status data reside locally on the embedded controller. Temperature setpoints, timer values, and zone activation states are retained through power cycles. For audit readiness, users may document calibration events using the built-in temperature calibration function—adjusting displayed readings against a certified reference probe at user-defined points. Though lacking USB or Ethernet connectivity, its deterministic UI response, absence of firmware updates during operation, and mechanical timer redundancy align with ALCOA+ principles (Attributable, Legible, Contemporaneous, Original, Accurate) for manual record-keeping in non-automated labs.

Applications

• Enzymatic reaction incubation (restriction digests, ligations, phosphorylations)
• Pre-PCR denaturation and hot-start activation
• Serum coagulation and clotting time assays
• DNA/RNA hybridization and probe labeling
• Cell lysate pre-warming and reagent equilibration
• Controlled drying of small-volume samples prior to mass spectrometry analysis
• Staged incubation of multi-component assay kits (e.g., ELISA development, lateral flow buffer optimization)

FAQ

What is the maximum operating temperature and its certified accuracy?
The HD200 achieves a maximum setpoint of 110 °C, with a guaranteed accuracy of ±0.3 °C at 37 °C and ±0.5 °C across the full range (0–110 °C), verified per manufacturer’s calibration protocol.

Can all four zones operate at different temperatures simultaneously?
No—the HD200 maintains identical setpoint temperature across all four zones at any given time; however, each zone supports independent timer control, allowing staggered start/stop sequences for samples introduced at different times.

Is the transparent lid compatible with UV sterilization procedures?
The blue acrylic lid is not UV-resistant and will degrade under prolonged exposure to germicidal UV-C (254 nm); it is intended for physical containment only and should be removed before UV decontamination of the chamber interior.

Does the unit support external temperature logging?
The HD200 does not include analog or digital output ports for continuous external data capture; temperature verification requires periodic spot-checking with a calibrated external probe.

What electrical certifications does the device hold?
It complies with IEC 61010-1:2010 for safety of laboratory electrical equipment and carries CE marking for EMC Directive 2014/30/EU and Low Voltage Directive 2014/35/EU; full test reports are available upon request from Hanuo technical support.
