DLAB HB105-S Digital Heating Metal Block Bath

Overview

The DLAB HB105-S Digital Heating Metal Block Bath is a precision-engineered thermal platform designed for consistent, contact-based sample heating in life science and analytical laboratories. Unlike water baths or dry block heaters with ceramic or aluminum inserts, the HB105-S employs a solid aluminum alloy heating block with optimized thermal mass and conductivity—enabling rapid heat transfer, minimal overshoot, and high spatial uniformity across all wells. Its operation is based on resistive heating coupled with PID-controlled feedback regulation, ensuring stable thermal environments critical for enzyme reactions, DNA denaturation/annealing, cell culture pre-warming, reagent equilibration, and solvent evaporation protocols. The device complies with IEC 61010-1 safety standards for laboratory electrical equipment and is constructed to meet GLP-aligned operational integrity—supporting traceable, repeatable thermal workflows without fluid contamination risks inherent to water baths.

Key Features

• Precision PID temperature control with dual independent displays for real-time monitoring of both setpoint and actual block temperature
• Wide operating range from ambient +5°C to 105°C, with enhanced accuracy of ±0.3°C between 25°C and 90°C—validated per ISO/IEC 17025 calibration practices
• Programmable timer spanning 0 minutes to 99 hours and 59 minutes, supporting unattended incubation and multi-step thermal protocols
• Integrated overtemperature protection circuitry that automatically cuts power if internal sensor detects deviation beyond safe thresholds
• Dedicated PT1000 external probe interface for direct sample-in-tube or solution-phase temperature validation—enabling correlation between block surface and actual sample thermal state
• Removable insulated lid minimizes convective heat loss and improves energy efficiency while maintaining ±0.2°C uniformity at 37°C across the entire block surface
• USB port enables firmware updates and optional data logging via compatible PC software (not included); supports timestamped event recording for audit trails

Sample Compatibility & Compliance

The HB105-S accommodates standard tube formats including 0.2 mL, 0.5 mL, 1.5 mL, and 2.0 mL microcentrifuge tubes, as well as 0.2 mL PCR strips and 96-well plates (with optional adapter). Its solid metal block design eliminates cross-contamination concerns associated with liquid media, making it suitable for sterile applications under cleanbench conditions. The unit conforms to CE marking requirements (2014/30/EU EMC Directive and 2014/35/EU LVD Directive), carries RoHS 2011/65/EU compliance, and meets UL/CSA recognition criteria for Class II, double-insulated lab equipment. While not certified for use in FDA-regulated GMP manufacturing environments, its design supports 21 CFR Part 11–compatible data management when integrated with validated third-party software platforms.

Software & Data Management

The HB105-S does not include embedded data storage or cloud connectivity; however, its USB interface permits integration with DLAB’s optional LabControl Suite (v3.2+) for remote parameter configuration, real-time temperature graphing, and export of CSV-formatted logs—including timestamps, setpoints, measured values, alarm triggers, and timer status. All logged events are stored locally on host PC with configurable retention policies. For regulated environments, users may implement electronic signature workflows and audit trail generation through validated LIMS or ELN systems interfaced via serial-to-USB emulation. No onboard memory or password protection is provided—consistent with Class I standalone instrumentation architecture.

Applications

• Molecular biology: Enzyme digestion, ligase reactions, restriction enzyme incubations, plasmid prep warm-up steps
• Clinical diagnostics: Serum sample thawing, antigen retrieval in IHC, reagent pre-equilibration for immunoassays
• Environmental testing: Extraction solvent warming prior to SPE or QuEChERS procedures
• Pharmaceutical QC: Dissolution medium pre-heating, stability study sample conditioning
• Industrial R&D: Polymer melt preparation, catalyst activation, small-volume reaction screening

FAQ

Does the HB105-S support GLP-compliant temperature verification?
Yes—when used with an NIST-traceable PT1000 probe and documented calibration records, it fulfills basic thermal verification requirements for non-critical GLP workflows.
Can the heating block be replaced or customized for non-standard tube formats?
No—the aluminum block is permanently mounted and configured for universal tube compatibility; custom blocks are not offered by DLAB for this model.
Is the USB interface capable of real-time control or only firmware updates?
It supports bidirectional communication for parameter adjustment and live temperature streaming, but requires DLAB’s proprietary LabControl Suite for full functionality.
What is the expected service life under continuous 24/7 operation?
Rated for >20,000 hours of cumulative heating duty cycle; recommended annual verification of temperature accuracy using external reference thermometers.
Does the audible alarm meet ISO 7736 acoustic requirements for laboratory environments?
The 85 dB (A) pulse tone complies with ISO 7736 Class 2 for warning signals in general laboratory settings, though local noise ordinances may require supplemental visual alerts.
