Overview
The WIGGENS WD310 Multi-Function Dry Block Thermostat is a precision-engineered temperature control platform designed for reproducible, contact-based thermal incubation of samples in vials, tubes, and microcentrifuge containers. Unlike liquid bath systems, the WD310 employs solid-state conductive heating via interchangeable aluminum blocks—eliminating evaporation, contamination risk, and maintenance associated with water or oil media. Its core architecture follows ISO/IEC 17025-aligned thermal management principles: a PT100-sensor feedback loop coupled with PID-controlled resistive heating ensures stable setpoint attainment within ±0.1 °C accuracy across its operational range (40–150 °C with PT100; 50–150 °C without). The unit’s stainless-steel heating chamber doubles as a compact dry-bath reservoir, enabling extended stability during unattended operation. Engineered for GLP-compliant laboratories, the WD310 meets mechanical safety requirements per EN 61010-1 and incorporates dual independent overtemperature protection—automatic power cutoff at 170 °C prevents thermal runaway under fault conditions.
Key Features
- Precision temperature control with ±0.1 °C resolution and accuracy, validated across the full 40–150 °C range when equipped with integrated PT100 sensor
- Four-digit LED display with real-time temperature readout and intuitive menu-driven calibration capability
- Modular aluminum heating block system—seven standard configurations available (0.2 mL to 25 mL capacity), all CNC-machined for uniform thermal conductivity and dimensional repeatability
- Stainless-steel heating chamber functions as a low-volume dry bath, supporting applications requiring ambient isolation and minimal thermal inertia
- Three operational modes: OFF (standby), OFF-TIME (timed shutdown), and WAIT-TIME (delayed activation)—enabling protocol-driven thermal sequencing without external controllers
- RS232 serial interface compliant with EIA/TIA-232-F standards, supporting bidirectional communication for remote parameter setting, real-time data logging, and firmware diagnostics
- Rapid thermal ramp rates (typical: 10–12 °C/min from ambient to 100 °C) combined with <±0.3 °C intra-block temperature uniformity (measured per ASTM E2209)
Sample Compatibility & Compliance
The WD310 accommodates standard laboratory consumables including PCR tubes (0.2–0.5 mL), microcentrifuge tubes (1.5–2.0 mL), screw-cap vials (10–25 mL), and custom-insert formats. All heating blocks are anodized for corrosion resistance and thermal stability. The device complies with IEC 61010-1:2010 for electrical safety in laboratory equipment and conforms to electromagnetic compatibility requirements per EN 61326-1. It supports audit-ready workflows under FDA 21 CFR Part 11 when used with validated third-party software (e.g., WIGGENS LabControl Suite), providing electronic signatures, change logs, and user-access controls. Temperature calibration certificates traceable to NIST standards are available upon request.
Software & Data Management
Via the optional WIGGENS LabControl software (v3.2+), users configure multi-step temperature profiles, export timestamped CSV datasets, and generate PDF reports with metadata (operator ID, block ID, calibration date). The RS232 interface enables integration into LIMS environments through standard SCPI command sets. All logged data include UTC timestamps, sensor status flags, and thermal deviation alerts. Audit trails record every parameter modification—including setpoint changes, mode transitions, and calibration events—with immutable user attribution and time-stamped digital signatures.
Applications
- Enzyme reaction incubation (e.g., restriction digests, ligations, kinase assays)
- Sample thawing and pre-warming prior to HPLC, GC, or mass spectrometry analysis
- Thermal denaturation studies in protein biochemistry
- Controlled drying of hygroscopic reagents or calibration standards
- Stability testing of reference materials under ISO 17034 guidelines
- QC/QA procedures in pharmaceutical manufacturing where dry-heat validation is required per USP <1211>
FAQ
Is the WD310 suitable for GMP-regulated environments?
Yes—when deployed with validated software and documented calibration records, it fulfills temperature-critical process steps in GMP-compliant analytical labs.
Can the heating block be replaced while the unit is powered on?
No—power must be disconnected and the unit allowed to cool below 40 °C before block exchange to prevent thermal shock and ensure operator safety.
Does the WD310 support external temperature probes?
It does not accept third-party probes; however, the built-in PT100 sensor can be field-calibrated using certified reference thermometers per ISO/IEC 17025 Clause 6.5.
What is the maximum allowable ambient temperature for continuous operation?
The unit is rated for uninterrupted use at ambient temperatures up to 30 °C with ≥10 cm clearance on all sides for convection cooling.
How often should calibration verification be performed?
We recommend quarterly verification using a traceable Class A PT100 thermometer, with full recalibration annually or after any physical impact or thermal excursion event.
