INFORS Orbitron Orbital Shaker

Overview

The INFORS Orbitron Orbital Shaker is a precision-engineered laboratory shaker designed for continuous, high-stability orbital motion in demanding life science applications—including microbial culture, cell suspension maintenance, enzyme assays, and reagent mixing. Operating on the principle of controlled orbital oscillation—where the platform rotates around a fixed horizontal axis with a defined 25 mm diameter orbit—the Orbitron delivers uniform, low-shear agitation without vertical displacement or mechanical resonance. Its five-point drive system ensures dynamic load balancing across the entire speed range (20–550 rpm), eliminating vibration transmission to adjacent equipment and maintaining positional stability even under asymmetric loading conditions. This architecture is especially critical in incubator-integrated workflows where thermal integrity and mechanical isolation are non-negotiable.

Key Features

• Five-point balanced drive mechanism with automatic load compensation—enables stable operation at all speeds and load distributions, minimizing mechanical noise and floor-transmitted vibration.
• Thermally optimized brushless DC motor with integrated thermal management: self-heating limited to <3°C during sustained high-speed operation, ensuring minimal thermal interference with temperature-sensitive samples.
• CO₂- and humidity-resistant motor housing and electronic enclosure—validated for uninterrupted use inside CO₂ incubators (5–20% CO₂, RH ≥95%) without corrosion or performance degradation.
• Soft-start and soft-stop ramping profiles prevent splashing during initiation and cessation of motion—critical for maintaining sterility and sample integrity in microbiological and mammalian cell cultures.
• IP43-rated composite polymer chassis—resistant to liquid ingress, chemical splashes, and microbial colonization; rounded edges and antimicrobial surface finish facilitate rapid decontamination and comply with GLP cleaning protocols.
• Modular platform system with three interchangeable sizes (N/F/M) secured via quick-release mechanical coupling—enabling tool-free platform swaps within seconds without recalibration.

Sample Compatibility & Compliance

The Orbitron accommodates a broad range of vessel formats through optional accessories: adhesive platforms for flasks and tubes, spring-loaded clamps for Erlenmeyer flasks (50–5000 mL), microplate holders (96-/384-well), and custom-fabricated fixtures for bioreactor bags or specialized bioprocessing containers. Its mechanical design conforms to IEC 61000-6-2 (immunity) and IEC 61000-6-4 (emission) standards. When operated inside certified incubators, the unit supports ISO 13485-aligned workflows and meets essential requirements for GMP-compliant upstream bioprocessing environments. The absence of exposed metal fasteners and sealed electronics ensure long-term reliability in humidified, CO₂-rich atmospheres—addressing a key failure mode observed in conventional shakers deployed in cell culture suites.

Software & Data Management

While the Orbitron operates via standalone digital control, its interface supports audit-ready operation in regulated settings. The LED display provides real-time feedback of setpoint and actual rpm, elapsed time, and operational status—all visible at distances up to 3 meters. Though not networked by default, the device’s deterministic timing logic and non-volatile parameter storage enable full traceability per run. When integrated into validated systems, it complies with FDA 21 CFR Part 11 requirements when paired with compliant LIMS or ELN platforms that capture timestamped start/stop events and user authentication logs. Firmware updates (if issued) follow version-controlled release procedures documented in INFORS’ Quality Management System (QMS), aligned with ISO 9001:2015.

Applications

• Mammalian and insect cell suspension culture in T-flasks, roller bottles, and wave bioreactors.
• Aerobic bacterial and yeast fermentation in baffled flasks under controlled O₂ transfer conditions.
• Antibody purification buffer exchange and column equilibration steps requiring gentle, consistent mixing.
• High-throughput assay preparation—including ELISA plate coating, antigen-antibody binding kinetics, and PCR master mix homogenization.
• Environmental microbiology workflows involving soil slurry resuspension and waterborne pathogen enrichment.

FAQ

Can the Orbitron be used inside a CO₂ incubator?

Yes—the motor and electronics are specifically sealed and materials selected to withstand continuous exposure to 5–20% CO₂ and relative humidity ≥95% without corrosion or functional drift.
What is the maximum flask size supported with standard clamps?

Standard spring clamps accommodate Erlenmeyer flasks up to 5 L; larger vessels require custom fixture design or platform adaptation.
Is calibration required before first use?

No factory calibration is needed—the speed control system is factory-trimmed to ±1 rpm accuracy across the full 20–550 rpm range and remains stable over time without user intervention.
Does the Orbitron support timed shutdown?

Yes—digital timer allows programmable run durations from 1 minute to 99 hours, 59 minutes, with automatic power-down and audible alert.
How is cleaning validated for GMP environments?

The IP43-rated shell and seamless antimicrobial surface allow wipe-down with 70% ethanol, isopropanol, or approved sporicidal agents; no disassembly is required for routine cleaning verification.
