WIGGENS WH-650 Temperature and Humidity Controlled Incubator

Overview

The WIGGENS WH-650 Temperature and Humidity Controlled Incubator is an engineered solution for precise, stable, and reproducible environmental conditioning of biological samples in research, pharmaceutical development, clinical diagnostics, and quality control laboratories. Designed and manufactured under German engineering standards, the WH-650 employs a high-fidelity PID temperature control algorithm coupled with a dual-sensor feedback loop to maintain thermal stability within ±0.1 °C at 37 °C — a critical benchmark for mammalian cell culture, microbial growth studies, and enzyme activity assays. Its chamber architecture integrates passive thermal management principles: high-density eco-friendly insulation minimizes surface temperature rise (<40 °C at ambient 25 °C), eliminating burn hazards while reducing energy consumption. The incubator operates across a wide working range (ambient +5 °C to 65 °C), supporting applications from low-temperature acclimation studies to accelerated stability testing per ICH Q1 guidelines.

Key Features

• Robust stainless-steel interior chamber and adjustable stainless-steel shelving (standard: 3 shelves; expandable up to 15) for optimal airflow distribution and easy decontamination.
• Dual-sealed, 5 mm thick tempered glass inner door with outer insulated metal door — provides real-time visual monitoring without compromising thermal integrity or humidity retention.
• Independent overtemperature protection circuitry: activates when chamber temperature exceeds user-defined threshold or factory-set safety limit (e.g., >70 °C), triggering audible/visual alarm, automatic heater shutdown, and power cutoff — compliant with EN 61010-1 safety requirements.
• Intelligent door-open response logic: internal fan and heating elements deactivate immediately upon door opening; after 60 seconds, an audible alert sounds to prevent prolonged exposure and thermal drift.
• Four integrated AC power outlets inside the chamber enable direct operation of peripheral devices (e.g., shakers, sensors, or pH monitors) without external cable routing.
• Front-panel digital interface with membrane keypad and large LED display supports intuitive parameter entry, real-time setpoint/status readout, and programmable timer (1 minute to 99 hours 59 minutes).

Sample Compatibility & Compliance

The WH-650 accommodates a broad spectrum of sample formats including Petri dishes, multiwell plates (6–96-well), flasks (T25 to T225), roller bottles, and custom bioreactor vessels — all supported by uniformly distributed convection airflow and minimal vertical/horizontal thermal gradients (<±0.5 °C at 37 °C and 25 °C RT). Its construction meets key regulatory design expectations: stainless-steel interior surfaces comply with ISO 14644-1 Class 5 cleanroom-compatible material specifications; electrical safety conforms to IEC/EN 61010-1; and operational documentation supports GLP and GMP audit readiness. While humidity control is not specified in base configuration, optional RH modules (sold separately) can be integrated to meet USP , EP 2.1.7, or ASTM E171 environmental test chamber criteria.

Software & Data Management

The WH-650 operates as a standalone instrument with embedded firmware — no proprietary software required for routine operation. However, it supports analog output (0–10 V or 4–20 mA) and RS485 Modbus RTU communication (optional interface module) for integration into centralized laboratory monitoring systems (e.g., DeltaV, LabArchives, or custom SCADA platforms). This enables continuous logging of temperature setpoints, actual chamber readings, alarm events, and door-open duration — fulfilling data integrity requirements under FDA 21 CFR Part 11 when paired with validated electronic record systems. All event timestamps are traceable and non-editable within the device’s internal memory buffer (retains last 1,000 events).

Applications

• Mammalian and insect cell culture requiring strict thermal fidelity (e.g., CHO, HEK293, Sf9 lines).
• Microbiological cultivation per ISO 8559, CLSI M22-A3, and USP / sterility and microbial limits testing protocols.
• Stability studies aligned with ICH Q1A(R3) long-term and accelerated conditions (e.g., 25 °C/60% RH, 30 °C/65% RH, 40 °C/75% RH — with optional humidity add-on).
• Enzyme kinetics, protein folding assays, and hybridization protocols sensitive to thermal transients.
• QC/QA workflows in biopharmaceutical manufacturing where equipment qualification (IQ/OQ/PQ) must demonstrate thermal uniformity, stability, and recovery performance.

FAQ

What is the chamber volume and usable internal dimensions?
The WH-650 offers a nominal 650 L internal volume, with usable internal dimensions of 700 mm (W) × 650 mm (D) × 1430 mm (H).
Does the WH-650 include humidity control?
The standard WH-650 model is a temperature-controlled incubator only. Humidity regulation requires an optional RH module (W6031650-HUM), which integrates seamlessly via factory calibration.
Is the unit suitable for GMP environments?
Yes — its stainless-steel chamber, traceable calibration support, alarm/event logging capability, and compliance with EN 61010-1 make it suitable for IQ/OQ/PQ execution in regulated settings.
How many shelves are included, and what is the maximum load capacity per shelf?
Three adjustable stainless-steel shelves are supplied as standard. Each shelf supports up to 15 kg evenly distributed load; total shelf count may be increased to 15 with optional reinforcement kits.
Can the incubator be connected to a building management system (BMS)?
Yes — via optional RS485 Modbus RTU interface or analog output, enabling remote status monitoring, setpoint adjustment, and alarm forwarding to facility-wide BMS networks.
