Overview
The Hettich HettCube Series represents a modular, CO₂-independent laboratory incubator platform engineered for precision temperature control and long-term operational stability in life science applications. Unlike traditional CO₂-dependent incubators, the HettCube relies on robust passive humidity retention combined with advanced PID-controlled heating and optional refrigeration circuits—enabling consistent thermal environments without gas supply infrastructure or associated calibration drift. Its core architecture integrates a double-walled insulated chamber with low-thermal-mass stainless-steel interior, minimizing temperature gradients and ensuring uniformity across the entire working volume (±0.3 °C at setpoint, typical). Designed for continuous operation under demanding laboratory conditions, the HettCube series meets the functional requirements of microbiological culture, cell maintenance (non-CO₂-requiring strains), enzyme activity assays, and stability testing per ICH Q1 guidelines. Each unit is assembled in Germany and undergoes factory validation for temperature distribution and recovery time per ISO 14644-1 Class 5 cleanroom-compatible protocols.
Key Features
- Modular scalability: Three base configurations—HettCube 200 (200 L), HettCube 400 (400 L), and HettCube 600 (600 L nominal volume; 351 L fully validated)—allow selection based on throughput, footprint, and regulatory validation scope.
- Refrigerated variants (R-models): Equipped with compressor-based cooling enabling operation from 0 °C to +65 °C—critical for psychrophilic culture, cold-chain simulation, or multi-temperature comparative studies.
- User-centric interface: High-contrast graphical LCD display with intuitive menu navigation, programmable ramp/soak profiles, and real-time logging of temperature history (last 30 days buffered).
- Passive humidity management: Optimized chamber sealing and internal water reservoir design maintain >85% RH at 37 °C without active humidification—reducing condensation risk and simplifying maintenance.
- Robust construction: All internal surfaces are electropolished stainless steel (AISI 316L); external casing features powder-coated steel with rounded corners for easy decontamination and compliance with ISO 15195:2013 cleaning validation standards.
- Integrated safety systems: Overtemperature cut-off (independent hardware thermostat), door-open alarm with audible/visual alert, and automatic power-down on critical sensor failure.
Sample Compatibility & Compliance
The HettCube accommodates standard microbiological and cell culture formats—including Petri dishes (up to 1800 × 90 mm plates in the HettCube 600), multiwell plates, test tubes, flasks, and roller bottles—via adjustable stainless-steel shelving with load-rated support (max. 25 kg/shelf). Its chamber geometry and airflow design minimize turbulence while ensuring laminar heat distribution, supporting growth consistency across heterogeneous sample loads. The system is designed for use in environments governed by EU MDR Annex I essential requirements, FDA 21 CFR Part 11–ready data export (via USB), and supports IQ/OQ documentation packages aligned with ISO/IEC 17025 and GxP principles. Validation reports include temperature mapping (per ASTM E2297-21), recovery time assessment (<15 min after 30-sec door opening), and alarm response verification.
Software & Data Management
While the HettCube operates as a standalone instrument, its embedded controller logs timestamped temperature readings every 60 seconds to non-volatile memory. USB export enables CSV-formatted data transfer for integration into LIMS or ELN platforms. Optional Ethernet connectivity (via Hettich Connect Module) adds remote monitoring, email alerts on deviation events, and audit-trail-enabled user access logs compliant with FDA 21 CFR Part 11 Annex 11 requirements. Firmware updates are delivered via signed firmware packages with SHA-256 verification, ensuring integrity during field upgrades.
Applications
- Microbiological quality control: Enumeration of aerobic mesophiles, coliforms, and pathogens in food, water, cosmetics, and pharmaceutical raw materials per ISO 4833-1, ISO 6222, and USP <61>.
- Biotechnology process support: Maintenance of bacterial cultures (e.g., E. coli, Bacillus spp.) and yeast strains during plasmid propagation, protein expression screening, and fermentation seed train preparation.
- Clinical diagnostics: Incubation of clinical specimens (urine, stool, wound swabs) prior to identification and susceptibility testing per CLSI M02-A12 and EUCAST guidelines.
- Environmental monitoring: Growth of indicator organisms from HVAC filters, cleanroom surfaces, and water distribution systems in regulated manufacturing facilities.
- Academic research: Long-duration experiments requiring stable thermal environments—e.g., biofilm formation assays, thermal tolerance profiling, and developmental biology studies using non-mammalian models.
FAQ
Does the HettCube require CO₂ gas supply or calibration?
No. The HettCube operates independently of CO₂ and does not incorporate gas sensors or flow controllers—eliminating routine gas calibration, consumables, and associated infrastructure costs.
Can the HettCube be validated for GMP environments?
Yes. Factory-provided IQ/OQ templates, temperature mapping reports, and traceable calibration certificates (DAkkS-accredited where applicable) support qualification in pharmaceutical and medical device manufacturing settings.
What is the maximum allowable ambient temperature for installation?
The unit is rated for operation in ambient temperatures up to +32 °C with ≤70% RH. For installations above 28 °C, adequate ventilation clearance (≥10 cm on all sides) and absence of direct sunlight are required to maintain specified performance.
Is remote monitoring supported out of the box?
Standard units include local display and USB data export. Remote monitoring requires optional Hettich Connect Module (Ethernet/WiFi) and compatible Hettich Cloud or on-premise server configuration.
How often does the water reservoir need refilling?
Under typical 37 °C operation, the integrated reservoir (capacity: 1.2 L) requires replenishment every 5–7 days. A low-level indicator appears on the display 48 hours prior to depletion.
