Overview
The DLAB H100-Pro Precision Metal Block Heater is an engineered thermal platform designed for accurate, stable, and reproducible temperature control of samples in sealed tubes and microplates during pre-analytical processing and biochemical incubation. Operating on solid-state conduction heating via a high-thermal-conductivity aluminum alloy block, the H100-Pro eliminates convective air currents—making it ideal for applications where sample evaporation, cross-contamination, or ambient interference must be minimized. Unlike water baths, this metal bath delivers rapid thermal response, superior positional uniformity, and compatibility with diverse tube formats without liquid maintenance. Its operating range—from ambient +5 °C to 100 °C—covers critical workflows including enzyme inactivation, DNA denaturation, antigen retrieval, and cell lysis buffer equilibration. The device complies with general laboratory safety standards IEC 61010-1 and is constructed to support routine use under ISO/IEC 17025-accredited quality management systems.
Key Features
- High-precision temperature control with ±0.5 °C accuracy across the full operating range and ±0.2 °C uniformity at 37 °C—validated per ASTM E2251 for thermal stability in laboratory heating devices;
- Magnetic module recognition system enabling tool-free, auto-identifying insertion of interchangeable heating blocks (e.g., 0.2 mL, 0.5 mL, 1.5/2.0 mL, 4×PCR, 96-well plate);
- Programmable timer with adjustable duration from 1 minute to 99 hours and 30 minutes, supporting both timed and continuous operation modes;
- Integrated self-calibration function accessible via front-panel interface, allowing users to perform traceable temperature verification without external equipment;
- Insulated transparent lid minimizes heat loss and maintains thermal consistency—particularly critical for low-power protocols and extended incubations;
- Compact footprint (200 × 235 × 120 mm) and lightweight design (7.3 kg) facilitate benchtop deployment in space-constrained environments such as biosafety cabinets or automated workstations.
Sample Compatibility & Compliance
The H100-Pro accommodates standard laboratory consumables—including PCR strips, microcentrifuge tubes (0.2–2.0 mL), deep-well plates, and flat-bottom 96-well plates—via user-swappable aluminum or stainless-steel blocks. All modules are CNC-machined to ISO 8655-compliant dimensional tolerances, ensuring repeatable thermal contact. The unit meets electromagnetic compatibility requirements per CISPR 11 Group 1, Class B, and carries CE marking for conformity with EU Directive 2014/30/EU (EMC) and 2014/35/EU (LVD). While not certified for GMP manufacturing environments, its programmable logging capability (when paired with optional RS232/USB data export) supports GLP-aligned documentation practices, including audit trails for temperature setpoints and runtime records.
Software & Data Management
The H100-Pro operates via an embedded microcontroller with non-volatile memory storing up to 10 user-defined programs. Though standalone by default, optional firmware upgrade enables serial communication (RS232 or USB virtual COM port) for integration into LIMS or ELN platforms. When connected, real-time temperature telemetry and event logs—including start/stop timestamps, setpoint changes, and calibration triggers—can be exported in CSV format. This architecture satisfies foundational data integrity expectations aligned with FDA 21 CFR Part 11 principles, particularly when combined with institutional procedural controls governing electronic record retention and user access management.
Applications
- Molecular biology: Enzyme restriction digestion, ligase inactivation, cDNA synthesis, and thermal cycling pre-steps;
- Clinical diagnostics: Serum sample thawing, reagent equilibration prior to immunoassay execution, and antigen unmasking in IHC workflows;
- Environmental testing: Extraction buffer conditioning for soil/water analysis (e.g., EPA Method 3545A preparation steps);
- Industrial QC labs: Viscosity reference standard tempering, polymer melt indexing prep, and stability study sample conditioning;
- Education & training: Demonstrating Arrhenius kinetics, Q10 temperature coefficient experiments, and thermodynamic equilibrium concepts in undergraduate labs.
FAQ
Does the H100-Pro support external temperature probe input for independent validation?
No—the unit relies on internal Pt100 sensor feedback only; however, the built-in self-calibration routine allows users to verify and adjust offset against a NIST-traceable reference thermometer.
Can multiple modules be heated simultaneously at different temperatures?
No—only one block is mounted and controlled at a time; multi-zone operation requires separate units or alternative instrumentation.
Is the insulated lid autoclavable?
No—the polycarbonate lid is not designed for steam sterilization; wipe-down with 70% ethanol or isopropanol is recommended for decontamination.
What is the expected service life under continuous 24/7 operation?
Rated for >20,000 hours of cumulative heating duty cycle when operated within specified ambient conditions (15–30 °C, <80% RH, non-condensing).
Does DLAB provide IQ/OQ documentation templates for lab validation?
Yes—DLAB supplies downloadable qualification protocol outlines (PDF) compatible with common lab validation frameworks; final execution remains the responsibility of the end-user’s QA department.
