INFORS Multitron Standard Orbital Shaking Incubator

Overview

The INFORS Multitron Standard Orbital Shaking Incubator is an engineered platform for high-fidelity microbial, cell culture, and fermentation applications requiring precise temperature control and reproducible orbital agitation. Based on Couette-flow-optimized magnetic drive technology, it delivers silent, maintenance-free operation with exceptional mechanical stability across its full speed range (20–400 rpm). Its chamber employs forced-air convection with dual-directional airflow distribution and insulated composite housing—eliminating thermal stratification and ensuring spatial temperature uniformity of ±0.2°C throughout the 240 L working volume. Designed for scalability in modern bioprocessing labs, the system supports up to three vertically stacked units, each independently addressable via a centralized RS-232 interface, enabling coordinated multi-condition experiments without cross-contamination risk or spatial redundancy.

Key Features

• Brushless DC magnetic drive system: Zero mechanical wear, no carbon dust generation, and <52 dB(A) acoustic emission at maximum speed—ideal for noise-sensitive core facilities.
• Triple-layer stackable architecture: Units interlock mechanically and thermally; optional base frame ensures structural integrity and vibration isolation under full load.
• Adhesive polymer tray surface: Eliminates need for flask clamps—Erlenmeyer flasks, test tubes, and custom vessels adhere securely during agitation, reducing setup time and glass breakage risk.
• Intelligent power recovery: Upon grid interruption, the controller retains all setpoints (temperature, speed, timer, orbit diameter); automatic resumption occurs at pre-failure parameters after power restoration.
• Full-access hinged door: Reinforced downward-opening design supports >35 kg static load—serves as a stable staging surface for pipetting or sample handling adjacent to active cultures.
• IPX2-rated enclosure: Internally isolated electronics and external mounting of moisture-sensitive components permit safe wipe-down cleaning with aqueous disinfectants between runs.

Sample Compatibility & Compliance

The Multitron Standard accommodates standard microbiological and bioprocess vessels—including 250 mL to 5000 mL Erlenmeyer and Fernbach flasks, multi-well plates (with compatible carriers), and custom bioreactor bags mounted on auxiliary trays. Its temperature range (4–60°C) meets ASTM E2924-22 requirements for incubator qualification in QC microbiology, while ±0.1°C stability satisfies ISO 20387:2018 Annex B criteria for biosafety level 2 (BSL-2) environmental control. The RS-232 interface supports integration into validated laboratory information management systems (LIMS) and complies with FDA 21 CFR Part 11 when paired with audit-trail-enabled host software. All thermal and agitation parameters are traceable to NIST-traceable references per GLP documentation protocols.

Software & Data Management

While the Multitron Standard operates via an integrated membrane keypad with real-time LCD display, its RS-232 port enables bidirectional communication with third-party data acquisition platforms (e.g., LabVIEW, Python-based PySerial scripts, or enterprise LIMS). Users may log timestamped temperature, speed, and runtime data at user-defined intervals (1 s to 60 min resolution). Optional INFORS LogView software provides CSV export, trend visualization, and alarm-triggered email notifications—supporting 21 CFR Part 11-compliant electronic records when deployed with role-based access controls and digital signature modules.

Applications

• High-yield recombinant protein expression in E. coli and yeast using controlled exponential-phase agitation profiles.
• Seed train expansion for mammalian cell culture prior to bioreactor inoculation—maintaining consistent k_La across scales.
• Antibiotic susceptibility testing (AST) under standardized ISO 20776-1:2021 incubation conditions.
• Environmental microbiology: Enumeration of heterotrophic plate count (HPC) organisms per APHA Standard Methods 9215B.
• Enzyme kinetics assays requiring simultaneous thermal stabilization and homogeneous mixing of reaction mixtures.
• Algal biomass production trials where photoperiod synchronization is coupled with orbital shear modulation.

FAQ

Can the Multitron Standard operate continuously for extended periods (e.g., >72 hours)?
Yes—the magnetic drive system and sealed bearing architecture are rated for uninterrupted operation up to 10,000 hours under nominal load conditions.
Is remote monitoring possible without upgrading hardware?
Basic serial logging is supported natively; Ethernet or Wi-Fi connectivity requires an external RS-232-to-Ethernet converter compliant with Modbus RTU protocol.
What validation documentation is provided with shipment?
Each unit ships with a Factory Acceptance Test (FAT) report including as-delivered temperature mapping (9-point grid), speed calibration certificate, and electrical safety test record (IEC 61010-1).
How does the adhesive tray perform with high-viscosity media (e.g., 2% agarose or methylcellulose gels)?
Adhesion remains effective up to 15 cP viscosity at 25°C; for higher viscosities, stainless steel clamp trays are recommended to prevent lateral slippage during low-speed agitation.
Are spare parts such as trays, clamps, and door gaskets available through global distributors?
Yes—INFORS maintains a 10-year spare parts inventory commitment; all consumables and wear components carry unique part numbers traceable to batch-manufacturing records.
