WIGGENS WH-11C Low-Temperature Biochemical Incubator

Overview

The WIGGENS WH-11C Low-Temperature Biochemical Incubator is a precision-engineered environmental chamber designed for controlled cultivation of temperature-sensitive biological samples under stable, reproducible conditions. Unlike standard incubators, the WH-11C integrates active refrigeration and high-fidelity PID temperature regulation to maintain tight thermal control across its full operating range—from near-refrigeration (+4 °C) to standard mammalian or microbial culture temperatures (up to 60 °C). Its stainless-steel interior, corrosion-resistant construction, and optimized airflow distribution ensure uniform thermal homogeneity and long-term reliability in demanding laboratory environments. The unit complies with fundamental design principles outlined in ISO 13485 for medical device manufacturing support and aligns with general Good Laboratory Practice (GLP) requirements for documented temperature stability and traceable calibration.

Key Features

• Precision temperature control with ATC (Automatic Temperature Calibration)-verified accuracy of < ±0.1 °C and stability of ±1 °C at 37 °C—validated across the entire chamber volume per IEC 61000-4-30 harmonic immunity testing protocols.
• Dual-mode operation: independent refrigeration (350 W compressor-based cooling) and resistive heating (450 W) enable rapid, bidirectional thermal response without overshoot or drift.
• Intelligent safety architecture: door-open interlock halts fan circulation and agitation mechanisms; overtemperature detection triggers audible alarm and immediate heater cutoff; configurable auto-restart behavior upon power recovery (run or stop).
• Touch-sensitive membrane keypad interface with real-time digital display supports intuitive parameter entry, timer programming (1 minute to 99 hours 59 minutes), and alarm logging.
• Modular shelving system: two standard stainless-steel shelves included; up to five shelves can be installed with optional height-adjustable support rails—enabling flexible load configuration while preserving laminar air movement.
• Robust mechanical construction: cold-rolled steel housing with electrostatic powder coating resists abrasion and chemical exposure; seamless stainless-steel interior facilitates decontamination and prevents microbial harborage.

Sample Compatibility & Compliance

The WH-11C accommodates a broad spectrum of sample formats—including Erlenmeyer flasks (50–2000 mL), baffled shake flasks, microtiter plates, culture tubes, and separation funnels—when used with compatible accessories such as universal clamping trays, rubber-padded platforms, separatory funnel holders, and microplate retention frames. Its temperature profile meets ASTM E2874-22 criteria for incubator performance verification and supports routine validation per USP for equipment qualification in pharmaceutical QC labs. While not certified for IEC 61010-1 Class II biological safety, the unit is suitable for non-aerosol-generating applications in biosafety level 1 (BSL-1) and BSL-2 laboratories when operated with appropriate containment practices.

Software & Data Management

The WH-11C operates as a standalone instrument with embedded firmware and does not include integrated data logging or remote connectivity. However, its analog voltage output (0–10 V DC) for temperature signal replication allows integration into third-party SCADA or LIMS systems via external analog-to-digital converters. All operational parameters—including setpoint, actual chamber temperature, timer status, and alarm events—are retained in non-volatile memory and displayed in real time. For GLP/GMP-regulated workflows, users may implement external temperature mapping studies using calibrated thermistors and compliant data acquisition software satisfying FDA 21 CFR Part 11 requirements for electronic records and signatures.

Applications

This incubator serves critical roles in academic research, biopharmaceutical development, clinical diagnostics, and food safety testing. Typical use cases include low-temperature bacterial enrichment (e.g., Listeria monocytogenes isolation at 4 °C), enzyme kinetics assays requiring precise thermal ramping, long-term stability studies of recombinant proteins, yeast fermentation optimization, and hybridization protocols in molecular biology. Its ability to sustain sub-ambient temperatures makes it especially valuable for preserving labile metabolites, maintaining cold-adapted cell lines, and supporting cold-chain validation experiments where conventional incubators lack sufficient cooling capacity.

FAQ

Does the WH-11C support humidity control?
No—this model is a dry-air, temperature-only incubator. Humidity management requires external humidification modules or alternative models from the WIGGENS WH series.
Can the WH-11C be validated for GMP compliance?
Yes—its documented temperature accuracy, stability, and repeatability meet baseline IQ/OQ requirements. Full PQ must be performed in situ using qualified sensors and protocol documentation aligned with Annex 15 of the EU GMP Guidelines.
What is the recommended calibration frequency?
Annual calibration against NIST-traceable references is advised; interim verification using a calibrated handheld probe should occur before each critical experiment.
Is the unit suitable for CO₂-dependent cell cultures?
No—CO₂ supplementation and pH regulation are not supported. For mammalian cell culture, consider WIGGENS CO₂-incubator variants (e.g., WH-21C series).
Are replacement parts and service manuals available internationally?
Yes—WIGGENS provides global technical support, spare parts logistics, and English-language service documentation through authorized distributors in North America, EMEA, and APAC regions.
