BOXUN BSD-WX(F)3350 Large-Capacity Horizontal Incubator Shaker

Overview

The BOXUN BSD-WX(F)3350 is a large-capacity horizontal incubator shaker engineered for high-throughput, temperature-sensitive biological applications requiring precise control of both thermal environment and mechanical agitation. Designed around a dual-mode oscillation architecture—supporting both orbital (circular) and reciprocating (linear) motion—the instrument delivers consistent, reproducible mixing across diverse vessel formats and culture volumes. Its operational principle relies on PID-controlled forced-air convection for uniform temperature distribution and brushless DC motor-driven motion systems that maintain constant torque and speed stability across the full frequency range. This combination ensures optimal oxygen transfer, suspension homogeneity, and metabolic consistency in microbial, mammalian, and enzymatic cultures—critical for applications aligned with GLP-compliant bioprocess development, QC microbiology, and upstream biomanufacturing workflows.

Key Features

• Intelligent microprocessor controller with audible/visual alarm system for environmental anomaly detection (e.g., overtemperature, motor overload, power interruption)
• Large backlit LCD display showing real-time setpoints and measured values for temperature, speed, amplitude, and remaining time
• Parameter lock function to prevent unauthorized or accidental modification during operation
• Multi-segment programmable curve control (up to 10 segments) enabling complex ramp-hold-cool protocols
• Extended timer capability up to 999 hours with automatic shutdown and alarm upon completion
• Brushless DC motor drive ensuring zero maintenance, low noise (<55 dB), and stable low-speed performance (±1 rpm accuracy)
• Imported precision bearings and reinforced chassis for extended service life and minimal vibration transmission
• Triple safety architecture: independent overtemperature cutoff, door interlock switch, and current-limiting circuit protection
• Electrostatically coated steel exterior and electropolished stainless-steel inner chamber (mirror-finish AISI 304); rounded corners for ISO 5 cleanroom-compatible cleaning
• Gas inlet port compatible with nitrogen or CO₂ purging for anaerobic or controlled-atmosphere experiments
• Ergonomic flip-top lid design with concealed wiring and recessed control panel for durability and operator safety

Sample Compatibility & Compliance

The BSD-WX(F)3350 accommodates standard laboratory vessels ranging from 50 mL test tubes to 5 L Fernbach flasks, with verified compatibility for Erlenmeyer flasks (50–5000 mL), baffled bottles, cell culture bags (via custom mounting), and multi-well plates (with optional platform adapters). Its chamber dimensions (1035 × 675 × 470 mm) support simultaneous loading of up to 15 × 2 L flasks or 109 × 100 mL flasks under optimized airflow conditions. The unit complies with IEC 61010-1:2010 for electrical safety and meets EN 60335-1 requirements for laboratory equipment. Temperature uniformity (±1°C at 25°C, empty chamber) and stability (±0.2°C at 37°C) are validated per ASTM E2500-13 guidelines for qualification of laboratory thermal equipment. Optional data logging modules support 21 CFR Part 11–compliant audit trails when paired with validated software.

Software & Data Management

While the base configuration operates via embedded firmware, optional connectivity modules enable integration into centralized lab informatics infrastructure. The GPRS alarm module transmits real-time fault alerts (e.g., temperature deviation >±2°C, power loss) via SMS to designated personnel. A USB-enabled thermal printer option provides hard-copy output of time-temperature-speed profiles for batch records. For networked environments, the optional PC monitoring interface supports TCP/IP communication, remote parameter adjustment, and CSV-formatted data export—including timestamped temperature and RPM logs—for traceability in FDA-regulated quality systems. All digital outputs retain metadata (operator ID, method name, calibration status) required for ISO/IEC 17025 accreditation.

Applications

This shaker serves as a core platform in academic research laboratories studying bacterial growth kinetics, yeast fermentation optimization, and recombinant protein expression in shake-flask bioreactors. In pharmaceutical QA/QC labs, it supports USP / microbial limit testing and media growth promotion studies under controlled aerobic conditions. Biotechnology facilities use it for seed train expansion, plasmid stability assays, and enzyme activity screening across thermal gradients. Environmental microbiology labs employ its wide amplitude range for soil slurry homogenization and biofilm dispersion studies. Food safety laboratories apply it to pathogen enrichment protocols (e.g., Salmonella pre-enrichment in BPW) where precise 35–42°C incubation with gentle agitation is mandated by AOAC Official Methods.

FAQ

What is the difference between the BSD-WX3350 and BSD-WF3350 models?
The BSD-WX3350 features orbital shaking motion (Φ26 mm amplitude), while the BSD-WF3350 uses reciprocating motion (0–50 mm adjustable amplitude); both share identical temperature control, timer, and chamber specifications.
Can this shaker be used for anaerobic culture applications?
Yes—the integrated gas inlet port allows connection to inert gas sources (e.g., N₂ or 5% CO₂/95% N₂) to displace oxygen within the chamber prior to and during operation.
Is the temperature calibration traceable to national standards?
Factory calibration is performed using NIST-traceable PT100 sensors; users may perform field verification with external Class A platinum resistance thermometers per ISO/IEC 17025 procedures.
Does the device support continuous operation beyond 999 hours?
No—the maximum timer setting is 999 hours; however, the auto-restart function after power recovery enables unattended multi-day runs without manual intervention.
Are third-party vessel clamps compatible with the standard platform?
The platform accepts industry-standard universal clamps (e.g., New Brunswick Scientific, Infors HT); BOXUN also supplies proprietary quick-release bottle holders for rapid reconfiguration between flask sizes.
