Overview
The LY WD-2110B Advanced Programmable Metal Block Heater (Model 131-1020) is a precision-engineered dry bath system designed for consistent thermal control in molecular biology, clinical diagnostics, and quality control laboratories. Unlike water baths, this metal block heater employs direct conductive heating via an aluminum alloy heating block—ensuring rapid thermal response, minimal evaporation risk, and contamination-free sample handling. Its microprocessor-based PID temperature control algorithm delivers high reproducibility across the full operating range (ambient +5°C to 105°C), making it suitable for critical applications including DNA denaturation prior to PCR, enzyme inactivation, serum coagulation assays, and controlled incubation of reagents during assay preparation. The device complies with general laboratory safety standards for Class II electrical equipment and is constructed to support routine use under GLP-aligned workflows.
Key Features
- High-resolution dual LED display showing real-time temperature and countdown timer simultaneously
- Interchangeable aluminum heating modules (C1–C7) for flexible tube format compatibility—from 0.2 mL PCR strips to 5.0 mL centrifuge tubes
- Thermal stability of ±0.3°C maintained at both low (40°C) and high (100°C) setpoints, verified per ISO/IEC 17025 calibration traceability practices
- Programmable timer up to 99 hours 59 minutes with audible end-of-cycle alert and auto-shutdown functionality
- Over-temperature protection circuitry with independent thermal cutoff (110°C threshold) for fail-safe operation
- User-accessible temperature offset calibration function to compensate for minor sensor drift over extended service life
- Compact footprint (176 × 160 × 121 mm) and lightweight design (1.5 kg) enabling seamless integration into biosafety cabinets, cold rooms, or benchtop workstations
Sample Compatibility & Compliance
The WD-2110B accommodates standardized tube formats used across life science protocols—including 0.2 mL, 0.5 mL, 1.5 mL, 2.0 mL, and 5.0 mL microcentrifuge tubes, as well as 6 mm diameter test tubes. All interchangeable modules feature precision-machined wells with tight dimensional tolerances (±0.05 mm) to ensure uniform thermal contact and minimize inter-tube temperature variance. While not certified to IEC 61010-1 for hazardous locations, the unit meets general-purpose electrical safety requirements for laboratory environments per GB 4793.1–2007 (equivalent to IEC 61010-1:2010 Ed.3). It supports documentation practices aligned with FDA 21 CFR Part 11 when paired with external audit-trail-capable LIMS or ELN systems.
Software & Data Management
This model operates as a standalone instrument without proprietary software or USB connectivity. All configuration and monitoring are performed locally via the front-panel keypad and dual-line LED display. However, its stable thermal performance and repeatable timing behavior make it compatible with automated lab workflows using external PLC-triggered start/stop signals (via optional relay interface kit, sold separately). Temperature logs can be manually recorded for batch traceability; users implementing electronic recordkeeping may integrate the device into validated SOPs requiring documented calibration history, maintenance logs, and periodic performance verification per ASTM E2877-22 (Standard Guide for Thermal Validation of Dry Block Heaters).
Applications
- DNA template denaturation and primer annealing steps in pre-PCR setup
- Controlled coagulation of serum or plasma samples for clinical chemistry panels
- Enzyme deactivation following restriction digestion or ligase reactions
- Pre-warming of reagents (e.g., agarose solutions, staining buffers) to reduce condensation artifacts
- Stabilization of thermolabile compounds during sample preparation prior to HPLC or mass spectrometry analysis
- Consistent heat shock protocols in bacterial transformation workflows
FAQ
What is the maximum recommended continuous operating temperature?
The unit is rated for sustained operation up to 105°C. Prolonged use above 100°C should include periodic visual inspection of module surface integrity and thermal seal condition.
Can multiple modules be calibrated independently?
No—calibration offset applies globally to all installed modules. For applications requiring multi-zone validation, separate instruments or modular systems with individual PID loops are recommended.
Is the C3 module included by default?
Yes, the standard configuration ships with the C3 module (39 × 1.5 mL capacity). All other modules are available as optional accessories.
Does the device support external data logging?
Not natively. Real-time temperature output is not provided via analog or digital interface. Integration with third-party dataloggers requires external PT100 probe placement adjacent to the block surface.
How often should temperature accuracy be verified?
Per ISO/IEC 17025 recommendations, verification should occur before each analytical campaign or at least daily when used in regulated environments. A traceable NIST-calibrated thermometer (e.g., Fluke 1523 with dry-well calibrator) is advised for routine checks.
