Overview
The DLAB HB150-S2 Dual-Channel Digital Metal Block Heater is a precision-engineered thermal platform designed for consistent, reproducible sample incubation, enzyme inactivation, DNA denaturation, and reagent pre-warming in molecular biology, clinical diagnostics, and pharmaceutical QC laboratories. Unlike water baths, this metal block heater employs solid aluminum heating blocks with high thermal conductivity and low thermal inertia, enabling rapid temperature equilibration and minimal overshoot. Its dual independent heating zones—each with dedicated digital control—allow simultaneous operation at two distinct setpoints (e.g., 37°C and 95°C), supporting parallel workflows such as PCR setup and restriction digest incubation without cross-contamination risk or shared thermal drift. The unit operates on the principle of resistive heating coupled with PID-controlled feedback via integrated platinum RTD sensors, ensuring stable thermal output across the full operating range (ambient +5°C to 150°C).
Key Features
- Dual independent heating channels with separate digital displays for real-time monitoring of both temperature and countdown timer
- PID temperature control algorithm delivering ±0.3°C accuracy between 25–90°C and ±0.6°C from 90–150°C, validated per ASTM E220 standards for thermal calibration
- High uniformity performance: ±0.2°C across the block surface at 37°C, confirmed using multi-point NIST-traceable probe mapping
- Integrated over-temperature safety cutoff with automatic shutdown to prevent sample degradation or equipment damage
- Optional external PT1000 sensor input for direct sample temperature feedback—enabling closed-loop control where block-to-sample thermal lag must be minimized
- Removable insulated lid module reduces convective heat loss by >40%, improving energy efficiency and long-term stability during extended incubations
- LED display with 0.1°C resolution and audible alert upon completion of timer or attainment of setpoint
- Compact footprint (290 × 210 × 120 mm) and lightweight design (3.2 kg) optimized for benchtop integration in ISO Class 5–7 cleanrooms and regulated GMP environments
Sample Compatibility & Compliance
The HB150-S2 accommodates standard tube formats including 0.2 mL, 0.5 mL, 1.5 mL, and 2.0 mL microcentrifuge tubes, 96-well PCR plates (with optional adapter), and small-volume vials (up to 15 mL). Its aluminum block architecture supports rapid thermal transfer while minimizing condensation risks associated with water-based systems. The device complies with IEC 61010-1:2010 for laboratory electrical equipment safety and meets electromagnetic compatibility requirements per EN 61326-1. For regulated environments, the timer function supports ALCOA+ data integrity principles when paired with lab notebook documentation; although not natively 21 CFR Part 11 compliant, audit trails can be generated manually for GLP/GMP audits.
Software & Data Management
The HB150-S2 operates as a standalone instrument with no embedded firmware or network connectivity. All parameter inputs—including temperature setpoint, dwell time, and alarm activation—are executed via front-panel membrane buttons and stored in volatile memory only during active use. No data logging, USB export, or remote interface is provided. This design prioritizes operational simplicity, electromagnetic noise immunity, and validation transparency—key considerations for QC labs performing IQ/OQ/PQ under ISO/IEC 17025 or FDA guidance. Users requiring electronic record retention may integrate external calibrated data loggers connected to the PT1000 port.
Applications
- Enzyme reaction incubation (e.g., ligase, polymerase, phosphatase assays)
- Cell lysis and protein extraction protocols requiring precise thermal ramping
- Standardization of ELISA plate warming prior to assay initiation
- Thermal inactivation of nucleases and proteases in RNA/DNA preparation workflows
- Pre-heating of reagents for chromatography mobile phase preparation
- Stability testing of formulations at accelerated temperatures (e.g., 40°C, 60°C, 85°C)
- Calibration support for thermocouple verification against reference standards
FAQ
Does the HB150-S2 support programmable ramping or gradient profiles?
No—the unit maintains a single user-defined setpoint per channel and does not offer rate-controlled heating or cooling profiles.
Can the heating blocks be interchanged for different tube formats?
Yes—DLAB offers optional interchangeable aluminum blocks (e.g., for 96-well plates or 15-mL conical tubes) sold separately under part numbers HB-BLK-96 and HB-BLK-15M.
Is the external PT1000 sensor included with the unit?
No—the PT1000 probe is an optional accessory (model PT1000-EXT) and must be ordered separately.
What is the warm-up time from ambient to 100°C?
Typical stabilization time is ≤12 minutes for a fully loaded 1.5-mL tube block, measured per ASTM E742 guidelines using a calibrated handheld thermometer.
Does the device require routine calibration?
Yes—DLAB recommends annual verification using a NIST-traceable reference thermometer; calibration certificates are available through authorized service centers.
