WIGGENS WH-05G GMP-Compliant Temperature-Controlled Incubator

Overview

The WIGGENS WH-05G is a precision-engineered, GMP-compliant temperature-controlled incubator designed for regulated life science laboratories requiring strict adherence to Good Manufacturing Practice (GMP), ISO 13485, and ICH Q5 guidelines. It employs air-jacketed heating architecture—where heated air circulates uniformly around the stainless steel chamber—to deliver exceptional thermal stability and minimal gradient deviation across the entire 50 L working volume. Unlike water-jacketed systems, this design eliminates condensation risks, reduces maintenance overhead, and ensures rapid temperature recovery after door openings. The unit is validated for continuous operation at setpoints from +5°C above ambient to 65°C, with certified accuracy of < ±0.3°C and stability of ±0.1°C at the critical 37°C benchmark—meeting USP <1031> and ASTM E1912 requirements for incubator performance qualification. Its fully sealed, double-gasketed door assembly and seamless, radius-rounded AISI 304 stainless steel interior minimize microbial retention and support routine sanitization with alcohol, hydrogen peroxide vapor (HPV), or quaternary ammonium compounds—critical for cell culture, bioburden testing, and stability studies under GLP/GMP audit conditions.

Key Features

• Air-jacketed thermal system with independent PID-controlled heating circuit ensures uniform temperature distribution and fast stabilization (<15 min to reach 37°C from ambient)
• GMP-ready construction: electropolished stainless steel chamber (AISI 304), rounded internal corners (R ≥ 5 mm), no crevices or welded seams in contact zones
• High-resolution capacitive touchscreen interface with multi-level user access control (operator, supervisor, administrator) and configurable password protection
• Dual-stage over-temperature safety: primary controller limit + independent mechanical cut-off switch (adjustable up to 70°C), triggering audible alarm, visual LED flash, and automatic power disconnection
• Door interlock logic halts fan and heater upon opening; integrated timer initiates audible alert after 60 seconds if door remains open
• Tempered 5 mm borosilicate glass inner door with low-emissivity coating provides real-time observation while minimizing radiant heat loss and surface condensation
• Three adjustable stainless steel shelves (2 standard, 1 optional) with perforated design for optimal airflow penetration and cross-contamination mitigation
• Energy-efficient insulation using halogen-free polyurethane foam (35 mm thickness) limits external surface temperature to <40°C at 65°C internal setpoint

Sample Compatibility & Compliance

The WH-05G accommodates a broad range of biological and pharmaceutical samples—including adherent and suspension mammalian cell cultures, microbial growth assays (e.g., sterility testing per USP <71>), enzyme activity studies, and accelerated stability chambers for ICH Q1A(R3) protocols. Its stainless steel interior complies with ISO 14644-1 Class 5 cleanroom-compatible surface roughness (Ra ≤ 0.8 µm) and passes ISO 10993-5 cytotoxicity screening when cleaned per manufacturer-recommended SOPs. The unit supports installation qualification (IQ), operational qualification (OQ), and performance qualification (PQ) documentation packages aligned with FDA 21 CFR Part 11 electronic record requirements. All firmware logs—including temperature history, alarm events, door status, and user actions—are time-stamped, non-erasable, and exportable via RS232 for audit trail generation.

Software & Data Management

The WH-05G integrates seamlessly with WIGGENS’ optional WinIncubate™ data logging software (v3.2+), enabling real-time remote monitoring, automated CSV report generation, and configurable alarm escalation (email/SMS). Logged parameters include chamber temperature (every 10 s), setpoint deviation, door open duration, and fault codes—all stored in encrypted binary format with SHA-256 checksum integrity verification. Audit trails meet ALCOA+ principles (Attributable, Legible, Contemporaneous, Original, Accurate, Complete, Consistent, Enduring, Available) and are exportable in PDF/A-1b format for regulatory submissions. Firmware supports FOTA (Firmware Over-The-Air) updates via USB port, with version rollback capability and cryptographic signature validation to prevent unauthorized modification.

Applications

• Cell line expansion and maintenance under cGMP-compliant conditions for biologics manufacturing
• Microbial enumeration and challenge studies per ISO 11133 and Ph. Eur. 2.6.12
• Stability testing of drug substances and products per ICH Q1 series guidelines
• In vitro diagnostic (IVD) reagent incubation and calibration verification
• Environmental monitoring sample incubation (e.g., settle plates, contact plates, air samplers)
• Quality control of probiotic formulations and live biotherapeutic products (LBPs)
• Academic and contract research organization (CRO) labs requiring ISO/IEC 17025 traceable thermal validation

FAQ

Does the WH-05G comply with FDA 21 CFR Part 11 for electronic records and signatures?

Yes—the device’s firmware and optional WinIncubate™ software provide role-based access control, electronic audit trails, and secure, non-modifiable data storage meeting all technical and procedural requirements of Part 11 Subpart B.
Can the incubator be validated for IQ/OQ/PQ per GAMP 5 guidelines?

Yes—WIGGENS provides a full qualification protocol template (including sensor placement maps, acceptance criteria, and test methods) compatible with PQ instruments traceable to NIST standards.
Is humidity control available on the WH-05G model?

No—the WH-05G is a temperature-only incubator. For combined temperature/humidity control, refer to the WH-05GH series, which adds ultrasonic humidification and RH feedback loop (range: 30–95% RH, ±3% RH accuracy).
What is the maximum allowable load weight per shelf?

Each stainless steel shelf is rated for 15 kg distributed load; total chamber load must not exceed 45 kg to maintain airflow integrity and thermal uniformity.
How often does the unit require calibration verification?

Per ISO/IEC 17025 and internal SOPs, we recommend annual calibration using a UKAS-accredited dry-block calibrator with traceable Pt100 probes, supplemented by quarterly in-house checks using calibrated reference thermometers.
