Overview
The Polish-made ST2 Forced-Air Incubator is a precision-engineered environmental chamber designed for reproducible, long-term cell culture, microbiological growth, enzyme assays, and stability testing in academic, pharmaceutical, and clinical laboratories. Utilizing forced convection via a high-efficiency vertical airflow system, the ST2 ensures rapid thermal equilibration and exceptional spatial uniformity across its 150 L working volume. Its microprocessor-based control architecture maintains setpoint accuracy within ±0.2°C over time and delivers temperature homogeneity of ±0.55°C throughout the chamber—validated per ISO 15189 and ASTM E145-22 standards for laboratory incubators. The unit operates across a broad ambient-compensated range from +3°C (above ambient) to +70°C, enabling both mesophilic and thermophilic applications without external cooling. A 75 mm-thick insulated door with integrated door-open detection sensor enhances thermal integrity and supports automated logging of access events—a critical feature for GxP-regulated workflows.
Key Features
- Vertical forced-air circulation system optimized for laminar flow distribution and minimal sample disturbance
- Microprocessor controller with digital LED display, 6-step programmable protocol capability, and non-volatile memory that retains all settings during power interruption
- Comprehensive safety suite: over-temperature/under-temperature alarms, self-diagnostic routines, and automatic cut-off protection
- RS232C serial interface for remote monitoring, data export, and integration into centralized lab management systems
- Three fully adjustable, corrosion-resistant stainless-steel shelves; load capacity up to 15 kg per shelf
- Electropolished stainless-steel interior with seamless corners and antimicrobial coating for ease of decontamination and ISO Class 5 cleanroom compatibility
- Ergonomic design featuring rounded edges, chemical-resistant powder-coated exterior, and intuitive front-panel navigation
Sample Compatibility & Compliance
The ST2 accommodates standard tissue culture flasks (T25–T225), Petri dishes (up to 150 mm), multiwell plates (6–96-well), and glassware up to 500 mL in volume. Its humidity control (20–65% RH) supports non-condensing cultivation of sensitive mammalian lines and fungal isolates. The unit complies with IEC 61010-1:2010 for electrical safety and meets EN 60335-2-86:2013 for laboratory equipment. When operated with validated firmware and connected to a 21 CFR Part 11–compliant data acquisition system, it satisfies documentation requirements for GLP, GMP, and ISO/IEC 17025 accreditation. Routine performance qualification (PQ) can be executed using calibrated NIST-traceable probes per USP and EU Annex 15 guidelines.
Software & Data Management
While the ST2 operates autonomously via its embedded controller, its RS232C port enables bidirectional communication with third-party PC-based platforms such as LabVIEW, MATLAB, or custom LIMS integrations. Optional firmware upgrades support CSV log export at user-defined intervals (1 min–24 h), timestamped event tagging (door open/close, alarm triggers), and real-time graphing of temperature/humidity trends. Audit trails are generated in accordance with ALCOA+ principles—attributable, legible, contemporaneous, original, accurate, complete, consistent, enduring, and available—ensuring full traceability during regulatory inspections.
Applications
- Mammalian and insect cell line propagation under controlled CO₂-free conditions
- Bacterial and yeast growth kinetics studies requiring tight thermal regulation
- Enzyme activity profiling across defined temperature gradients
- Stability testing of biologics, vaccines, and excipients per ICH Q1A(R2)
- Seed germination and plant tissue culture under standardized humidity regimes
- Quality control of diagnostic reagents and sterile medical devices
FAQ
Does the ST2 support CO₂ concentration control?
No—the ST2 is a temperature- and humidity-controlled forced-air incubator only. For CO₂-dependent cultures, consider pairing it with an external gas mixing module or selecting a dedicated CO₂ incubator model.
Is calibration certificate included with shipment?
A factory-issued calibration report (traceable to national standards) is provided upon request; on-site IQ/OQ/PQ services are available through authorized service partners.
Can the incubator be operated inside a biosafety cabinet?
Due to its heat dissipation profile and ventilation requirements, the ST2 must be installed in a well-ventilated room with ≥10 cm clearance on all sides and above the unit.
What is the warranty coverage?
The ST2 carries a 24-month limited warranty covering parts and labor for defects in materials and workmanship under normal laboratory use.
How often should preventive maintenance be performed?
Annual verification of temperature uniformity, humidity sensor drift, and airflow velocity is recommended per ISO/IEC 17025 Clause 6.4.3 and manufacturer technical bulletin TB-ST2-PM-2023.
