WIGGENS WH-850 Temperature-Controlled Incubator

Overview

The WIGGENS WH-850 Temperature-Controlled Incubator is a high-capacity, precision-engineered laboratory incubator designed for reliable, long-term cell culture, microbiological growth, and biochemical incubation under strictly regulated thermal conditions. Utilizing advanced digital PID temperature control architecture, the WH-850 maintains exceptional thermal uniformity and stability—±0.1 °C at 37 °C—with accuracy of ±0.5 °C across its operational range of +5 °C above ambient to 65 °C. Its robust thermal insulation system employs environmentally compliant materials to minimize surface temperature rise, eliminating burn hazards while optimizing energy efficiency. The unit is engineered for continuous operation in GLP-compliant environments and meets fundamental safety requirements per IEC 61010-1 for laboratory electrical equipment.

Key Features

• Digital PID temperature controller with Bias correction function—enables rapid recalibration in response to environmental drift or sensor offset without hardware intervention.
• Dual-seal tempered glass door (5 mm thick) with integrated LED illumination—provides unobstructed visual monitoring while maintaining thermal integrity and minimizing condensation.
• Independent overtemperature protection circuit—activates independently of the main controller; triggers audible alarm, flashing indicator, and automatic power cutoff when exceeding user-defined or factory-set thresholds.
• Intelligent door-open response protocol—immediately disables heating and fan operation upon door opening, followed by an audible alert after 60 seconds to prevent prolonged thermal loss and sample exposure.
• Three standard stainless steel shelves (polyester-coated), height-adjustable and optimized for airflow distribution; up to 15 shelves supported for high-density applications.
• Power recovery mode selection—users may configure auto-resume or manual restart behavior following unexpected power interruption, supporting uninterrupted experimental continuity where required.
• Front-panel timer with 1-minute to 99-hour 59-minute range—supports timed incubation cycles, sterilization hold periods, or scheduled shutdowns without external controllers.

Sample Compatibility & Compliance

The WH-850 accommodates diverse biological and chemical sample formats—including Petri dishes, multiwell plates, flasks, and roller bottles—within its 850 L chamber volume. Its stainless steel interior (electropolished and polyester-coated) resists corrosion from routine disinfectants (e.g., 70% ethanol, 1% sodium hypochlorite) and facilitates rapid decontamination. The unit complies with ISO 13485 design principles for medical device support equipment and incorporates safety mechanisms aligned with EN 61010-1:2010+A1:2019. While not inherently humidity-controlled (humidification requires optional add-on module), its thermal performance remains validated per ASTM E1753–22 for laboratory incubators used in microbiological and cell culture applications.

Software & Data Management

The WH-850 operates as a standalone instrument with no embedded data logging or network connectivity. All operational parameters—including setpoint, actual temperature, timer status, and alarm history—are displayed via a high-contrast LED interface. For laboratories requiring audit-ready records, integration with external data acquisition systems is supported via analog output (0–10 V DC) for real-time temperature monitoring. Optional RS-485 communication modules (sold separately) enable connection to centralized building management systems or LIMS platforms compliant with FDA 21 CFR Part 11 when paired with validated third-party software solutions. Calibration certificates traceable to DAkkS-accredited standards are available upon request.

Applications

• Cell culture maintenance (adherent and suspension lines) under stable 37 °C CO₂-free conditions.
• Bacterial and fungal growth studies requiring precise thermal profiles across extended durations (e.g., AST, biofilm formation assays).
• Enzyme activity assays and protein stability testing where thermal consistency directly impacts kinetic reproducibility.
• Seed germination, plant tissue culture, and entomological rearing protocols demanding large-volume uniformity.
• Stability testing of pharmaceutical intermediates and diagnostic reagents per ICH Q1A(R2) guidelines (when used within defined temperature ranges).
• Quality control incubation for food microbiology labs adhering to ISO 6579-1 and AOAC methods.

FAQ

Does the WH-850 include built-in humidity control?
No—the WH-850 is a temperature-controlled incubator only. Humidity regulation requires an optional external humidification module, which must be specified at time of order.
What is the maximum number of shelves that can be installed?
The unit supports up to 15 stainless steel shelves (standard configuration includes 3); additional shelf kits and support rails are available as accessories.
Is the WH-850 suitable for use in cleanroom environments?
Yes—its sealed construction, non-shedding stainless steel interior, and absence of internal fans or recirculation ducts make it compatible with ISO Class 5–8 cleanrooms when installed with appropriate air handling infrastructure.
Can the incubator be calibrated in-house?
Yes—users may perform field verification using NIST-traceable PT100 probes; full calibration with adjustment requires authorized WIGGENS service personnel due to firmware-level PID parameter access.
What safety certifications does the WH-850 carry?
It bears CE marking per the Low Voltage Directive (2014/35/EU) and EMC Directive (2014/30/EU), and conforms to IEC 61010-1:2010+A1:2019 for laboratory electrical equipment safety.
