WIGGENS WH-1200 Temperature and Humidity Controlled Large-Capacity Incubator

Overview

The WIGGENS WH-1200 is a large-capacity, temperature- and humidity-controlled incubator engineered for high-throughput life science applications requiring stringent environmental stability across voluminous chamber space. Designed with a total internal volume of 1204 L, it serves laboratories engaged in scalable cell culture, bioprocess development, microbial propagation, tissue engineering, and long-term stability studies where uniform thermal distribution and rapid environmental recovery are non-negotiable. Its operational principle relies on five-sided direct heating combined with four independently mounted high-efficiency circulation fans located at the rear-bottom of the chamber—ensuring laminar airflow distribution and minimizing thermal stratification. The chamber maintains stable setpoints within ±0.5°C to ±0.7°C at 37°C (measured per ISO 15189 and ASTM E2872 protocols), with recovery to nominal conditions achieved within 12 minutes after a 5-minute door opening event. All critical electronics—including microprocessor-based PID controllers, sensor signal conditioners, and safety interlocks—are housed in a modular, service-accessible control enclosure, supporting GLP-compliant maintenance logging and third-party calibration traceability.

Key Features

• Five-sided direct heating system with dynamic power modulation ensures precise thermal input aligned to real-time chamber demand.
• Four rear-mounted axial fans generate uniform air velocity profiles, validated by ISO 15189-compliant mapping to guarantee ≤±0.7°C spatial deviation at 37°C.
• Heated, low-emissivity observation window prevents condensation during high-humidity operation (up to 95% RH at 37°C), maintaining optical clarity without mechanical wiping or desiccant use.
• Six independent, fused AC outlets (10 A each) integrated into the left chamber wall—electrically isolated from main supply—enable concurrent operation of shakers, roller bottles, or sensors without cross-interference.
• Roller-bottle track system embedded in the chamber floor supports GMP-grade roller culture devices up to 10 L capacity, with precision-aligned guide rails for repeatable positioning and vibration-dampened mobility.
• Multi-point access architecture includes a centrally located, silicone-sealed port (Ø30 mm) on the right side wall for sterile sampling, probe insertion, process monitoring, and IQ/OQ validation documentation.
• Full SUS304 stainless-steel interior (electropolished finish) meets USP endotoxin limits and supports validated cleaning cycles per FDA 21 CFR Part 11 Annex 11 requirements.

Sample Compatibility & Compliance

The WH-1200 accommodates diverse sample formats including stacked multi-layer flasks (T225, CellSTACK®), roller bottles (up to 10 L), bioreactor bags (2D/3D), Petri dishes, microtiter plates, and environmental test chambers. Its chamber geometry permits simultaneous deployment of up to 35 adjustable shelves (optional), each rated for 50 kg static load. The unit complies with IEC 61010-1 (Safety Requirements for Electrical Equipment), EN 60529 (IP20 ingress protection), and conforms to essential performance criteria outlined in ISO 13408-1 (Aseptic Processing) and EU Directive 2014/30/EU (EMC). Humidity control functionality satisfies ISO 14644-1 Class 7 cleanroom ambient compatibility when installed with appropriate HVAC integration.

Software & Data Management

While the WH-1200 operates via an embedded 5-digit LED controller with manual setpoint entry, optional analog (0–10 V / 4–20 mA) and RS485 Modbus RTU interfaces enable integration into centralized BMS or LIMS platforms. Logged parameters—including chamber temperature, door-open events, fan status, and alarm triggers—are time-stamped with UTC synchronization and support audit-trail generation compliant with 21 CFR Part 11 when paired with validated third-party data acquisition software. Real-time analog outputs allow connection to chart recorders or PLCs for continuous environmental trending, while digital alarms provide dry-contact relay outputs for external notification systems.

Applications

• High-density adherent and suspension cell culture scaling (e.g., CHO, HEK293, iPSC expansion).
• Microbial fermentation pre-culture and inoculum preparation under controlled humidity.
• Long-term stability testing of biologics, vaccines, and diagnostic reagents per ICH Q5C guidelines.
• Environmental stress testing of medical devices and packaging materials per ISO 11607-1.
• Support infrastructure for automated liquid handling workcells requiring stable ambient staging zones.
• Academic and industrial bioprocess development labs requiring reproducible, auditable incubation environments across multi-user facilities.

FAQ

What is the maximum shelf loading capacity per level?
Each optional adjustable shelf is rated for 50 kg distributed load, supporting standard T225 flasks, roller bottles, or stackable culture vessels.
Does the WH-1200 support CO₂ control?
The WH-1200 is a temperature/humidity-controlled incubator; CO₂ functionality is available in the companion WCI-1200 model, which integrates dual-beam infrared CO₂ sensing and ±0.1% accuracy at 5% setpoint.
Can the unit be validated for GxP environments?
Yes—the modular control architecture, stainless-steel construction, documented thermal mapping capability, and optional data logging interfaces support IQ/OQ/PQ execution per ASTM E2500 and EU Annex 15.
Is remote monitoring possible without third-party hardware?
Native Ethernet or Wi-Fi connectivity is not included; however, RS485 or analog outputs permit integration with existing facility SCADA or building management systems using standard protocol gateways.
What is the warranty coverage and service support structure?
WIGGENS provides a 24-month limited warranty covering parts and labor, backed by authorized service partners across North America, EMEA, and APAC regions with certified field engineers trained in ISO/IEC 17025-compliant calibration procedures.
