Overview
The BOXUN BSF Series Orbital Shaker is a robust, open-platform laboratory shaker engineered for high-throughput, non-temperature-controlled agitation of culture flasks, bottles, and tubes in shared incubation environments. Designed around the principle of orbital (circular) motion—generated via eccentric drive mechanism—the system delivers uniform, low-shear mixing ideal for microbial growth, cell suspension maintenance, solubilization, and reagent homogenization. Unlike incubated shakers, the BSF series operates without integrated heating or cooling, making it purpose-built for use inside environmental chambers, walk-in incubators, or ambient lab spaces where precise thermal control is managed externally. Its structural architecture emphasizes mechanical stability, long-term operational consistency, and compatibility with standard laboratory glassware and plastic vessels up to 5 L capacity.
Key Features
- Microprocessor-based PID controller with real-time environmental scanning logic ensures stable speed regulation across the full 0–350 rpm range (±1 rpm accuracy)
- Large LED display showing setpoint and actual values for speed, time, and operational status
- Non-volatile memory retains user-defined parameters after power interruption, eliminating repeated configuration
- Programmable timer with 0.1-hour resolution (0–99.9 h), featuring automatic shutdown and dual-tone audible/visual alarm at endpoint
- Brushless DC motor with constant torque output across all speeds—no carbon brushes, zero routine maintenance, and extended service life (>20,000 h MTBF)
- Soft-start acceleration circuitry prevents abrupt motion onset, minimizing sample splashing and vessel displacement
- Heavy-duty cast iron base and die-cast aluminum platform provide vibration damping and geometric rigidity under full load
- Single- or dual-shelf configurations accommodate diverse workflow demands; shelves are precision-machined for flatness and concentricity
Sample Compatibility & Compliance
The BSF shaker supports universal bottle and flask mounting using standard clamps, rubber mats, or custom fixtures. Standard configurations include support for 50 × 250 mL flasks (BSF-50S/D) or 46 × 250 mL flasks (BSF-46S/D), scalable to larger formats including up to seven 5 L bottles per shelf. All models comply with IEC 61000-6-3 (EMC emission standards) and IEC 61000-6-2 (immunity). While not certified for GLP/GMP production environments out-of-the-box, the device meets essential requirements for research-grade documentation: traceable operation logs (via external data logger integration), reproducible speed/timing profiles, and mechanical durability suitable for ISO 17025-accredited laboratories conducting method validation per ASTM D4084 or USP guidelines.
Software & Data Management
The BSF Series operates as a standalone instrument with no embedded PC interface or proprietary software. However, analog output signals (0–10 V or 4–20 mA) are available on select industrial variants for integration into building management systems (BMS) or SCADA platforms. For audit-ready workflows, users may connect external USB data loggers to record speed, runtime, and alarm events—supporting compliance with FDA 21 CFR Part 11 when paired with validated timestamped logging software. The absence of network connectivity eliminates cybersecurity risks associated with IoT-enabled devices while preserving operational simplicity and reliability.
Applications
- Batch cultivation of aerobic microorganisms (e.g., E. coli, yeast, bacilli) in shake flasks under controlled atmospheric conditions
- Cell suspension maintenance for hybridoma or CHO lines prior to bioreactor inoculation
- Solubility testing and dissolution profiling of pharmaceutical excipients and APIs
- Environmental microbiology: water sample mixing for MPN assays and nutrient broth enrichment
- Chemical synthesis: homogeneous mixing during reflux or room-temperature reactions
- Quality control labs performing repeatable viscosity screening or particle dispersion protocols
FAQ
Does the BSF Series support temperature control?
No. It is a non-thermostatic shaker intended for use inside externally regulated environments such as incubators or climate-controlled rooms.
Can the shaker operate continuously beyond 99.9 hours?
No—the maximum programmable duration is 99.9 h; however, manual restart is supported, and the memory function restores prior settings automatically.
Is the orbit diameter adjustable?
No. All BSF models feature a fixed 25 mm circular orbit optimized for flask stability and oxygen transfer efficiency.
What safety certifications does the unit carry?
It conforms to IEC 61010-1 (Safety Requirements for Electrical Equipment for Measurement, Control, and Laboratory Use) and carries CE marking for EMC and Low Voltage Directive compliance.
How is mechanical calibration performed?
Speed calibration is verified using an external handheld tachometer; no internal calibration routine is required due to brushless motor design and factory-trimmed feedback loop.
