Overview
The Langbo LB-2102 Vertical High-Capacity Incubated Orbital Shaker is engineered for reproducible, long-duration cultivation of microbial, mammalian, and insect cell cultures under precisely controlled temperature and agitation conditions. Utilizing orbital shaking dynamics—where trays rotate in a horizontal circular motion with a fixed 50 mm orbit diameter—the system ensures uniform suspension of cells and nutrients while minimizing shear stress on sensitive biological samples. Its vertical dual-tray architecture maximizes usable bench space without compromising payload capacity, supporting up to 24 × 1000 mL flasks per tier (48 total), making it suitable for high-yield fermentation, bioprocess development, and upstream biomanufacturing workflows in academic labs, contract research organizations (CROs), and quality control environments.
Key Features
- Microprocessor-controlled incubation with programmable multi-stage profiles (up to 10 time-temperature-speed segments) for complex kinetic studies and adaptive culture protocols.
- LCD backlit display showing real-time setpoints and measured values for temperature, speed, and elapsed time; parameters are password-locked to prevent unauthorized modification.
- Brushless DC motor drive delivering consistent torque across the full 40–280 rpm range, eliminating carbon brush wear and enabling stable low-speed operation critical for delicate suspension cultures.
- Double-layer insulated stainless steel chamber with mirror-finish interior, electrostatically coated exterior, and tempered glass observation window for visual monitoring without thermal disruption.
- Comprehensive safety architecture including independent mechanical over-temperature cut-off, door interlock switch, motor thermal protection, and automatic power-fail recovery that resumes pre-interruption settings upon grid restoration.
- Soft-start acceleration circuitry prevents abrupt motion onset, safeguarding fragile cultures and minimizing liquid splashing or foam formation during initiation.
- Adjustable fresh-air inlet and optional inert gas port (e.g., N₂ or CO₂) support anaerobic/microaerophilic cultivation and pH stabilization in closed-vessel systems.
Sample Compatibility & Compliance
The LB-2102 accommodates standard laboratory vessels—including Erlenmeyer flasks (250–1000 mL), baffled flasks, culture bottles, and deep-well plates—via interchangeable universal clamps mounted on two independently accessible 750 × 500 mm stainless steel trays. Its temperature uniformity of ±1 °C across the working chamber and stability of ±0.5 °C meet requirements for ISO/IEC 17025-accredited laboratories performing method validation under GLP or GMP frameworks. While not certified to FDA 21 CFR Part 11 out-of-the-box, optional USB data logging with timestamped audit trails supports compliance-ready documentation when paired with validated third-party software.
Software & Data Management
The base configuration operates via embedded firmware with local parameter storage and non-volatile memory retention. For enhanced traceability, the optional B-configuration includes a USB interface and dedicated PC software enabling real-time remote monitoring, export of time-stamped CSV logs (temperature, speed, runtime), and post-run analysis of thermal and kinetic profiles. All logged data include operator ID fields, event timestamps, and system status flags—facilitating alignment with ALCOA+ data integrity principles in regulated environments.
Applications
- High-density bacterial and yeast fermentation for recombinant protein expression
- Mammalian cell expansion in serum-free or chemically defined media
- Enzyme production and metabolic pathway optimization studies
- Antibiotic susceptibility testing and MIC determination under dynamic growth conditions
- Seed train preparation for bioreactor inoculation in process development
- Environmental microbiology assays requiring extended incubation with agitation
FAQ
Does the LB-2102 support humidity control?
Humidity regulation is available as an optional add-on module; standard configurations maintain ambient humidity only.
Can the shaker operate at 4 °C continuously?
Yes—the refrigeration system is rated for continuous operation from 4 °C to 60 °C with active cooling and heating elements.
Is the tray height adjustable between tiers?
No—the dual-tray spacing is fixed to optimize airflow and thermal distribution; however, each tray accepts variable-height clamps for mixed flask sizes.
What certifications does the device carry?
It complies with IEC 61010-1 (Safety Requirements for Electrical Equipment for Measurement, Control, and Laboratory Use) and meets EMC directive 2014/30/EU; CE marking applies to the EU market.
How is calibration verified?
Factory calibration includes NIST-traceable verification of temperature sensors and tachometric speed measurement; users may perform field checks using external PT100 probes and optical tachometers.
