GLTLab BH-602T Dual-Independent Digital Metal Bath

Overview

The GLTLab BH-602T is a dual-independent digital metal bath engineered for precise, stable, and reproducible dry heating in laboratory environments. Unlike water baths or heat blocks with shared thermal zones, the BH-602T integrates two physically separate aluminum heating modules—each with independent temperature control and real-time monitoring—enabling concurrent operation at two distinct setpoints. Its operation relies on resistive heating elements embedded within high-thermal-conductivity aluminum blocks, coupled with advanced PID (Proportional-Integral-Derivative) feedback regulation. This architecture ensures rapid thermal equilibration, minimal overshoot, and long-term stability—critical for applications requiring strict thermal protocol adherence, such as enzyme inactivation, DNA denaturation, sample digestion, and solvent evaporation. Designed for benchtop use in chemistry, biochemistry, clinical diagnostics, and quality control laboratories, the BH-602T delivers consistent thermal performance across its full operating range of ambient +10°C to 200°C.

Key Features

• Dual independent heating zones: Two aluminum blocks, each with dedicated temperature sensor, controller, and display—allowing simultaneous, non-interfering thermal processing at different setpoints.
• PID-controlled thermal regulation: Delivers ±0.1°C temperature accuracy and <±0.3°C uniformity across each module surface (measured at 100°C, center-to-edge).
• Integrated calibration function: User-accessible internal calibration via front-panel adjustment screw; enables traceable offset correction against reference thermometer readings—supporting ISO/IEC 17025-compliant instrument verification protocols.
• Programmable timer: Adjustable from 0 to 10 hours or continuous (infinite) mode; auto-shutdown upon completion enhances safety and energy efficiency.
• Modular compatibility: Supports interchangeable aluminum and stainless-steel heating blocks (e.g., for 0.2 mL, 0.5 mL, 1.5 mL, 2.0 mL, 15 mL, and 50 mL tubes); blocks are secured via spring-loaded clamping and installed using included removal tool.
• Compact footprint: 305 × 290 × 110 mm external dimensions minimize bench space usage while maintaining structural rigidity and thermal isolation between modules.

Sample Compatibility & Compliance

The BH-602T accommodates standard laboratory consumables including microcentrifuge tubes, PCR strips, glass vials, and reaction tubes. Its modular design permits selection of block configurations optimized for specific tube geometries and thermal mass requirements. All heating blocks comply with RoHS Directive 2011/65/EU for hazardous substance restrictions. The device meets IEC 61010-1:2010 safety requirements for electrical equipment used in laboratory settings. While not certified for medical device use under FDA 21 CFR Part 820, it is routinely deployed in GLP- and GMP-aligned QC labs where documented calibration, maintenance logs, and operational SOPs are maintained per internal quality systems.

Software & Data Management

The BH-602T operates as a standalone instrument with no embedded data logging or USB/RS-232 connectivity in base configuration. However, its analog output option (available upon request) provides 0–5 V DC signal proportional to actual block temperature—enabling integration into centralized lab monitoring systems (e.g., SCADA or LabVantage) for audit-ready temperature traceability. For users requiring electronic recordkeeping compliant with FDA 21 CFR Part 11, third-party data loggers (e.g., Omega OM-DAQPRO-5300 series) may be interfaced via the analog output port, supporting time-stamped temperature archives, alarm thresholds, and exportable CSV reports.

Applications

• Enzyme assays and protein denaturation studies requiring precise, reproducible thermal ramps.
• Sample preparation for HPLC, GC, and LC-MS workflows—including derivatization, hydrolysis, and solvent removal.
• Clinical specimen processing: serum separation, antigen retrieval, and nucleic acid extraction pre-heating steps.
• Quality control testing of pharmaceutical excipients and raw materials per USP and thermal stability guidelines.
• Materials science: polymer melt conditioning, catalyst activation, and small-scale thermal aging experiments.

FAQ

Does the BH-602T support remote control or computer interface?
No—the standard unit features only front-panel keypad and LED display. Optional analog voltage output (0–5 V) is available for external monitoring but does not enable bidirectional communication.
Can both modules operate at different temperatures simultaneously?
Yes—each module has an independent PID controller, allowing fully asynchronous setpoint programming and real-time temperature readout.
Is calibration documentation provided with the instrument?
A factory calibration certificate (traceable to NIM, China) is included. Users are responsible for periodic recalibration per their internal quality procedures.
What is the maximum recommended load per module?
For optimal thermal uniformity and response time, loading should not exceed 80% of the module’s physical capacity—for example, ≤24 × 1.5 mL tubes per block.
Are replacement heating blocks available separately?
Yes—all standard and custom-configured blocks (including deep-well and low-profile variants) are orderable with lead times of 2–4 weeks.
