Overview
The MMM Stericell Dry Heat Sterilizer Series is a CE-marked, GMP-aligned laboratory-grade dry heat sterilization system engineered for reliable depyrogenation and microbial inactivation of heat-stable materials—including glassware, metal instruments, powders, and non-aqueous pharmaceutical excipients. Operating on the principle of conduction- and convection-driven thermal lethality, the Stericell series delivers uniform, validated temperature distribution across the entire chamber volume at setpoints from ambient +10 °C up to 250 °C. Unlike steam-based autoclaves, dry heat sterilization avoids moisture-related corrosion or hydrolysis, making it indispensable for sterilizing oils, anhydrous substances, and components incompatible with saturated steam. Each unit complies with DIN EN ISO 17665-1 for moist heat and incorporates design elements aligned with ISO 13485 and EU Annex 1 requirements for sterile processing environments.
Key Features
- Microprocessor-controlled PID temperature regulation with dual independent sensors (chamber wall and load-sensing) ensuring ±0.5 °C stability at 180 °C and better than ±1.0 °C uniformity across the working volume (per DIN 12880 validation protocol)
- Integrated safety architecture: real-time monitoring of door position and exhaust airflow; immediate cycle termination and Class III alarm activation upon unauthorized door opening or airflow interruption
- Chamber construction from high-grade 304 stainless steel with double-walled insulation and silicone-sealed gasketing for thermal integrity and long-term corrosion resistance
- Configurable chamber capacities (55 L, 111 L, 222 L, 404 L, and 707 L) supporting both benchtop and floor-standing installations in QC labs, R&D facilities, and production cleanrooms
- Optional Class A removable PT-100 probe enables direct load temperature mapping during IQ/OQ/PQ qualification—fully traceable to national metrology institutes (e.g., DKD/DAkkS)
Sample Compatibility & Compliance
The Stericell series accommodates a broad range of sterilization loads: borosilicate glass vials and pipettes, stainless-steel surgical tools, ceramic filters, talc, lactose monohydrate, and other thermally stable solids. It supports standard sterilization cycles such as 160 °C for 120 min (for pyrogen reduction) and 180 °C for 30 min (for microbial kill verification per USP ). All models are designed to meet ISO 14644-1 Class 5 (ISO Class 5) cleanroom compatibility when equipped with HEPA-integrated air filtration. Documentation packages include Factory Acceptance Test (FAT) reports, 3Q protocols (IQ/OQ/PQ), and electronic audit trails compliant with FDA 21 CFR Part 11 when paired with optional data logging software.
Software & Data Management
Stericell units integrate with MMM’s optional SteriControl™ software suite, enabling full-cycle parameter logging (temperature, time, door status, alarm events), electronic signature capture, and PDF report generation. Data integrity safeguards include user-level access control (admin/operator/guest), encrypted storage, and tamper-evident timestamps. Raw data files are exportable in CSV and XML formats for integration into LIMS or MES platforms. The system supports 21 CFR Part 11 compliance through role-based permissions, electronic signatures, and immutable audit trails—validated per ASTM E2500 and ICH Q9 principles.
Applications
- Depyrogenation of glass containers and stoppers in parenteral manufacturing
- Sterilization of stainless-steel components prior to aseptic assembly
- Moisture removal and pre-baking of analytical standards and reference materials
- Thermal validation studies for dry heat processes under ISO 11137 and ISO 11140
- Residue-free sterilization of lubricants, silicones, and non-volatile excipients
FAQ
What temperature uniformity can be expected across the chamber during a 180 °C sterilization cycle?
Typical temperature uniformity is ≤ ±1.0 °C (95% confidence interval) across all defined test locations per DIN 12880, verified during factory OQ.
Is third-party IQ/OQ support available for GMP-regulated sites?
Yes—MMM-certified field service engineers provide full 3Q execution, including protocol development, witness testing, and final documentation aligned with Annex 1 and PIC/S TR 13.
Can the sterilizer be integrated into a central monitoring system via Ethernet or Modbus?
Standard models feature RS485 Modbus RTU; optional Ethernet/IP and OPC UA gateways are available for SCADA and BMS integration.
Does the system support automated calibration verification using external reference probes?
Yes—the removable PT-100 port allows simultaneous connection of certified reference thermometers for in-situ calibration checks without interrupting routine operation.
Are validation templates included for initial PQ execution?
Each unit ships with editable IQ/OQ/PQ templates compliant with ISO/IEC 17025 and ASTM E2500, pre-populated with chamber-specific sensor IDs and nominal operating parameters.
