WIGGENS WH-01 Mini Low-Temperature Incubator

Overview

The WIGGENS WH-01 Mini Low-Temperature Incubator is a compact, precision-engineered biochemical incubation platform designed for controlled-temperature storage and cultivation of sensitive biological samples in research, pharmaceutical development, and clinical diagnostics laboratories. Unlike conventional compressor-driven units, the WH-01 employs solid-state Peltier thermoelectric technology to deliver bidirectional thermal regulation—capable of both active cooling below ambient and precise heating up to +60 °C. This architecture eliminates mechanical vibration, refrigerant leakage risks, and acoustic noise typically associated with reciprocating compressors, thereby preserving cell integrity during long-term culture and minimizing microenvironmental disturbance during microscopy or assay readouts. Its air-jacketed stainless steel chamber ensures rapid thermal response, uniform heat distribution, and resistance to corrosion from repeated cleaning with ethanol, hydrogen peroxide vapor, or other common lab disinfectants.

Key Features

• Peltier-based thermoelectric cooling system: Energy-efficient, silent, and maintenance-free operation with no moving parts in the cold stage.
• Digital PID temperature control: Achieves ±0.3 °C stability across the full operating range (−10 °C to +60 °C), with programmable ramp rates and hold durations.
• Adjustable-brightness LCD interface: Displays real-time temperature curves, setpoint tracking, and system status—including elapsed time, remaining cycle duration, and alarm history.
• Variable-speed internal circulation fan: 0–100% continuous adjustment enables optimization of airflow for delicate cultures (e.g., adherent mammalian cells) or high-humidity applications (e.g., fungal growth).
• Multi-stage programmability: Supports up to four independent temperature protocols, each comprising five sequential steps (ramp, hold, repeat)—ideal for circadian rhythm studies, cold-shock induction, or stepwise differentiation protocols.
• Integrated safety architecture: Includes dual redundant overtemperature cutoffs, current-limiting circuitry, door-open detection with automatic heater/fan shutdown, and timed audible alert after 60 seconds of open-door exposure.
• Modular sterilization compatibility: Optional high-temperature dry-heat module (up to 180 °C) enables periodic decontamination without chemical residues—critical for mycoplasma-sensitive workflows or ISO 13485-certified device manufacturing environments.

Sample Compatibility & Compliance

The WH-01 accommodates standard microbiological and cell culture formats including Petri dishes (up to 150 mm), multiwell plates (6–96-well), Erlenmeyer flasks (up to 500 mL), and cryovial racks. Its stainless steel interior and smooth, crevice-free chamber geometry support routine cleaning validation per ASTM E2613 and EU GMP Annex 1 requirements. While the base unit does not include built-in data logging certification, its RS-232/USB interface allows integration with third-party compliant software platforms supporting 21 CFR Part 11 audit trails, electronic signatures, and secure user access controls—enabling deployment in FDA-regulated QC/QA labs conducting stability testing or bioburden monitoring.

Software & Data Management

The WH-01 operates autonomously via its embedded controller but offers optional PC connectivity for remote monitoring and data export. When paired with WIGGENS’ LabControl Suite (v3.2+), users can configure temperature profiles offline, download timestamped temperature logs in CSV format, generate calibration reports traceable to NIST-certified references, and implement role-based access control for SOP-driven operations. All recorded events—including alarms, power interruptions, door openings, and parameter changes—are time-stamped and retained onboard for ≥30 days, satisfying GLP documentation retention expectations.

Applications

• Low-temperature bacterial culture maintenance (e.g., E. coli DH5α at 4 °C for plasmid stability)
• Enzyme activity assays requiring sub-ambient thermal control (e.g., restriction digests at 16 °C)
• Plant tissue culture under photoperiod-independent chilling regimes
• Short-term storage of primary human PBMCs prior to flow cytometry
• Pre-incubation of diagnostic reagents to minimize thermal drift during assay setup
• Environmental simulation for ecotoxicology studies (e.g., cold acclimation of Daphnia magna)

FAQ

What is the lowest achievable temperature with the WH-01 in a 25 °C ambient environment?
The WH-01 achieves a minimum stabilized temperature of −10 °C under ISO 17025-defined test conditions (25 °C ambient, 50% RH, no load). Performance may vary slightly depending on chamber loading and ventilation clearance.
Does the WH-01 support humidity control?
No—this model is designed as a dry-air incubator. Humidity management requires external humidification accessories or alternative models such as the WIGGENS WH-20 series with integrated steam generators.
Can the sterilization module be retrofitted to an existing WH-01 unit?
Yes—provided the unit was manufactured after Q3 2021 and includes the required high-temp wiring harness and firmware revision v2.4 or later. Retrofitting must be performed by an authorized WIGGENS service technician.
Is the temperature sensor calibrated traceable to national standards?
Each WH-01 ships with a factory calibration certificate referencing PTB (Physikalisch-Technische Bundesanstalt) standards. On-site recalibration using NIST-traceable reference probes is supported via the service menu.
How does the Autostart function behave after a power failure?
If enabled, the incubator resumes the last active program upon power restoration—unless the interruption exceeded 15 minutes, in which case it defaults to standby mode to prevent uncontrolled thermal transitions.
