INFORS Minitron Cell CO₂ Incubator Shaker

Overview

The INFORS Minitron Cell CO₂ Incubator Shaker is a precision-engineered, compact orbital shaker-integrated incubation system designed for demanding small-scale bioprocess development and cell culture applications. It combines controlled orbital agitation, precise CO₂ regulation (0–20% v/v), dynamic humidity management (20–85% RH), and stable temperature control (±0.1°C stability, ±0.2°C uniformity) within a single 160 L chamber. Unlike conventional shakers or standalone CO₂ incubators, the Minitron Cell implements a fully sealed, contamination-minimized cavity architecture—critical for adherent mammalian cell lines, suspension cultures, microbial fermentations, and sensitive co-culture experiments. Its operation relies on brushless DC motor-driven orbital motion (25 mm or 50 mm selectable orbit diameter), eliminating mechanical wear, particulate generation, and electromagnetic interference—making it compliant with ISO Class 5 (ISO 14644-1) cleanroom environments. The system supports both continuous and intermittent shaking protocols, with programmable timer functionality spanning up to 9 days, 23 hours, and 59 minutes.

Key Features

• Sealed, particle-free chamber with rounded internal corners and smooth stainless-steel interior—designed for ISO 5-compatible cleaning and sterilization protocols.
• Side-hinged door with ergonomic access and automatic motion pause upon opening—ensuring operator safety and sample integrity during intervention.
• Dual-layer stacking capability with centralized or independent control via Ethernet interface—enabling scalable deployment in space-constrained labs without sacrificing individual parameter autonomy.
• Refrigerated variant available (+4°C to 65°C), supporting cryo-adapted strains, cold-sensitive transfection protocols, and low-temperature metabolic studies.
• Integrated IR-based CO₂ sensor with digital feedback loop, auto-calibration support, and drift compensation (<1% deviation over 2 years under normal use).
• Patented air circulation system delivering uniform laminar flow at 100 m³/h—eliminating thermal gradients and ensuring reproducible growth kinetics across all vessel positions.
• Self-tuning PID temperature controller with configurable safety cutoff—preventing thermal overshoot and protecting irreplaceable biological samples from accidental excursions.
• Non-static composite housing with high-efficiency insulation—reducing energy consumption while maintaining stable internal conditions during extended runs.

Sample Compatibility & Compliance

The Minitron Cell accommodates standard culture formats including Erlenmeyer flasks (100–3000 mL), multi-well plates (up to 6-well), roller bottles, and custom bioreactor vessels mounted on its 480 × 420 mm platform. Its maximum load capacity of 12 kg ensures compatibility with dense media preparations and heavy glassware. All environmental parameters—including CO₂ concentration, relative humidity, temperature, and agitation speed—are traceable and auditable per GLP/GMP requirements. The embedded controller logs timestamped setpoints and real-time values with optional export to CSV or LIMS-compatible formats. CO₂ control complies with ASTM D6340 for gas concentration verification; humidity calibration follows ISO 17025-accredited reference standards. The system meets IEC 61010-1 for laboratory equipment safety and carries CE marking for EU conformity.

Software & Data Management

Control is managed through INFORS’ proprietary TouchControl™ interface—a 7-inch capacitive touchscreen with intuitive graphical workflow navigation. All parameters (speed, temperature, CO₂, humidity, timer, lighting, UV cycle) are adjustable independently or as preconfigured methods. Data logging records every 10 seconds by default, storing ≥30 days of continuous operation history onboard. Remote monitoring and configuration are supported via Ethernet (TCP/IP), enabling integration into institutional SCADA networks or centralized lab infrastructure management systems. Audit trails include user ID, timestamp, parameter change, and reason code—fully compliant with FDA 21 CFR Part 11 requirements when paired with validated electronic signature modules. Firmware updates are delivered via secure HTTPS, preserving data integrity throughout lifecycle maintenance.

Applications

• Mammalian cell expansion for monoclonal antibody production and vaccine development.
• Microbial strain screening under variable O₂/CO₂ tension—particularly relevant for anaerobic or microaerophilic organisms.
• Hypoxia modeling using dynamic CO₂–O₂ interplay in conjunction with optional gas mixing modules.
• Stem cell differentiation assays requiring precise temporal control of mechanical stimulation and gaseous environment.
• High-throughput bioprocess optimization—leveraging dual-stack configuration for parallel condition testing (e.g., pH vs. agitation rate).
• Teaching laboratories conducting foundational bioreactor principles with full environmental transparency.

FAQ

Does the Minitron Cell support sterile filtration of incoming CO₂ gas?
Yes—the system includes an integrated 0.2 µm hydrophobic filter on the CO₂ inlet line to prevent microbial ingress during gas supply.
Can humidity be maintained at 37°C without condensation on vessel surfaces?
Yes—its active humidity control algorithm dynamically adjusts vapor delivery to match chamber temperature, minimizing dew point differentials and preventing condensation on flask walls.
Is UV sterilization programmable and validated?
UV-C irradiation (254 nm) is fully programmable (duration, intensity, frequency) and validated per ISO 15714 for surface decontamination of chamber interiors between runs.
What happens during unexpected power loss?
All operational parameters—including speed, temperature, CO₂ setpoint, and remaining timer—are retained in non-volatile memory and automatically restored upon power recovery.
Are third-party vessel holders compatible with the Minitron Cell tray?
Yes—the 480 × 420 mm platform accepts standardized universal clamping systems (e.g., INFORS QuickLock, Thermo Scientific FlexiClamp), allowing rapid reconfiguration for diverse vessel geometries.
