INFORS Multitron 95°C High-Temperature Orbital Shaking Incubator

Overview

The INFORS Multitron 95°C High-Temperature Orbital Shaking Incubator is an engineered solution for controlled microbial, enzymatic, and bioprocess studies requiring precise thermal and mechanical environments up to 95°C. Designed around Couette-type orbital shaking mechanics and a patented five-motor drive architecture, the system delivers stable, low-vibration agitation across the full operational temperature range—without compromising thermal integrity or electronic reliability. Unlike conventional incubated shakers with internal motor placement, the Multitron 95°C locates all heat-sensitive electronics—including brushless DC motors, power supplies, and microcontroller units—outside the incubation chamber. This externalized drive design eliminates thermal drift in control circuitry and ensures long-term calibration stability, even during continuous operation at maximum setpoint. The monolithic composite enclosure provides superior thermal insulation and electrostatic discharge (ESD)-free surface properties, supporting GMP-compliant cleanroom workflows and reducing condensation-related contamination risks.

Key Features

• Five-motor synchronized drive system enables automatic load balancing—maintaining consistent orbital motion and acoustic noise <52 dB(A) even with asymmetric flask distribution (e.g., single 5-L vessel on a 6-position platform).
• Downward-hinged, reinforced access door rated for static loads ≥35 kg—doubles as an integrated lab bench surface for pipetting, sampling, or sensor calibration without requiring auxiliary furniture.
• Modular stacking architecture supports single-, double-, or triple-tier configurations; each layer operates independently with full parameter control via centralized touchscreen or optional Ethernet interface.
• Intelligent power recovery: Upon grid interruption, the system retains all user-defined setpoints (temperature, rpm, orbit, timer) and resumes operation automatically upon power restoration—no manual reconfiguration required.
• IPX1-rated interior with external routing of water-sensitive components allows safe decontamination using aqueous disinfectants or steam wipes; no disassembly needed for routine cleaning.
• INFORS Adhesive Platform Technology: proprietary silicone-based surface enables secure, clamp-free fixation of Erlenmeyer flasks, test tube racks, and microtiter plates—reducing mechanical stress on culture vessels and minimizing cross-contamination risk during handling.

Sample Compatibility & Compliance

The Multitron 95°C accommodates standard microbiological and biopharmaceutical sample formats including glass and PETG flasks (50 mL to 5 L), roller bottles, deep-well plates, and custom bioreactor sleeves. Its uniform temperature field (±0.2°C across entire chamber volume, per ISO 15378 Annex A and ASTM E2500-13) meets qualification requirements for QC/QA laboratories operating under cGMP, GLP, and ISO/IEC 17025 frameworks. The external motor layout and sealed electronics conform to IEC 61000-6-2 (immunity) and IEC 61000-6-4 (emission) standards. Data logging complies with FDA 21 CFR Part 11 when paired with INFORS Labworldsoft v6.5+ (audit trail, electronic signatures, and role-based access control enabled).

Software & Data Management

Control and monitoring are managed through the embedded 7-inch capacitive touchscreen running INFORS’ real-time OS, supporting multi-language UI (EN/DE/FR/ES/CN). All operational parameters—including temperature ramp profiles, oscillation acceleration curves, and time-stamped event logs—are stored internally for ≥12 months. Optional Labworldsoft software enables remote supervision via TCP/IP, automated report generation (PDF/CSV), and integration into LIMS or MES platforms using OPC UA or Modbus TCP protocols. Calibration certificates (temperature, speed, orbit) are digitally signed and exportable in PDF/A-1b format for regulatory submission.

Applications

• Cultivation of thermophilic and hyperthermophilic microorganisms (e.g., Geobacillus stearothermophilus, Pyrococcus furiosus) under aerobic and microaerobic conditions.
• High-temperature enzyme kinetics assays and protein thermal stability screening (T_m determination).
• Accelerated stability testing of biologics and mRNA-LNP formulations per ICH Q5C guidelines.
• Seed train expansion for industrial fermentation processes where elevated temperature suppresses mesophilic contaminants.
• Material compatibility testing of single-use bioprocessing bags and tubing under dynamic thermal-mechanical stress.

FAQ

Can the Multitron 95°C operate continuously at 95°C without performance degradation?

Yes—the externalized drive architecture and forced-air convection system maintain thermal equilibrium within specification for indefinite operation at maximum setpoint.
Is external cooling required to achieve sub-ambient temperatures?

Yes; the base configuration supports minimum temperature of ambient +5°C. Integration with an optional recirculating chiller (e.g., JULABO F25) extends operational range to 15°C at 23°C ambient.
Does the adhesive platform require consumables or replacement over time?

No—the silicone matrix is chemically inert, autoclavable (121°C, 20 min), and retains adhesion after ≥500 cleaning cycles with 70% ethanol.
How is temperature uniformity validated across the chamber?

Per ISO 15378 Annex A, validation uses 9-point thermocouple mapping (3×3 grid) at three vertical levels; full reports are provided with factory calibration certificate.
Can multiple Multitron units be synchronized for parallel process runs?

Yes—via Labworldsoft’s “Cluster Mode”, up to 16 units can share master temperature/rpm profiles and trigger coordinated start/stop events.
