BOXUN BSD-WX(F)2280 High-Capacity Horizontal Orbital Shaker

Overview

The BOXUN BSD-WX(F)2280 is a high-capacity, microprocessor-controlled horizontal shaker engineered for demanding life science and bioprocessing applications requiring precise temperature regulation and reproducible orbital or reciprocating motion. Designed around a robust air-jacketed thermal enclosure and a low-maintenance DC brushless motor drive system, it delivers stable oscillation across a wide frequency range (30–300 rpm for orbital mode; 30–250 rpm for reciprocal mode) with programmable amplitude control (Ø26–50 mm). Its 1010 × 590 × 470 mm working chamber accommodates large-volume culture vessels—including up to six 2 L Erlenmeyer flasks or seven 5 L bottles—making it suitable for scalable microbial fermentation, suspension cell expansion, enzyme kinetics assays, and hybridization protocols where uniform heat transfer and mechanical agitation are critical. The unit operates within a controlled temperature range of 4–60 °C, with PID-based regulation ensuring ±0.2 °C stability at 37 °C and ±1 °C uniformity across the chamber at ambient setpoints.

Key Features

• Intelligent microprocessor controller with LCD backlit display showing real-time setpoints and measured values for temperature, speed, amplitude, and remaining time
• Programmable multi-segment curve control (up to 10 segments) supporting complex incubation-shaking protocols
• Extended timer function (0–1000 hours) with auto-stop and audible/visual alarm upon completion
• Brushless DC motor architecture providing constant torque, smooth acceleration/deceleration, zero carbon dust emission, and maintenance-free operation over extended service life
• Imported precision bearings and optimized mechanical damping for low-noise performance (<55 dB[A]) and enhanced operational longevity
• Dual safety architecture: independent over-temperature cutoff switch, door interlock sensor, and motor overheat protection with automatic power disconnection
• Anti-condensation defrost design minimizing internal temperature fluctuation during humidity cycling
• Electrostatically coated steel exterior and mirror-finish 304 stainless-steel interior with rounded corners for easy decontamination and compliance with GLP cleaning standards
• Integrated inert gas inlet port (optional configuration) for anaerobic or oxygen-sensitive cultures
• Tool-free tray access via ergonomic flip-lid mechanism with concealed wiring and recessed control panel for impact resistance during transport

Sample Compatibility & Compliance

The BSD-WX(F)2280 supports broad vessel compatibility—from 50 mL test tubes to 5000 mL bioreactor bottles—via interchangeable universal clamps and custom-fit platforms. Its large-format tray (950 × 530 mm or 920 × 560 mm) allows simultaneous processing of heterogeneous sample sets under identical thermal and mechanical conditions. The system meets structural and electrical safety requirements per IEC 61010-1:2010 and conforms to electromagnetic compatibility standards EN 61326-1:2013. While not certified for ISO 13485 or FDA 21 CFR Part 11 out-of-the-box, its data logging capabilities (when paired with optional thermal printer or PC interface) support audit-ready documentation in GxP environments when validated per laboratory SOPs.

Software & Data Management

The embedded controller logs all operational parameters—including temperature history, speed profile, and runtime—with timestamped records accessible via front-panel navigation. Optional PC connectivity enables real-time remote monitoring and historical data export in CSV format. The integrated thermal printer (optional) provides hard-copy traceability of temperature-speed curves, satisfying basic record retention needs in academic and QC labs. For regulated environments, users may implement third-party validation packages to establish electronic signature workflows and audit trails compliant with 21 CFR Part 11 requirements.

Applications

• High-yield bacterial and yeast fermentation in research-scale bioreactors
• Suspension culture of mammalian and insect cells under controlled O₂/CO₂ conditions (with gas inlet option)
• Protein expression studies requiring synchronized induction and agitation
• Nucleic acid hybridization and immunoassay plate washing protocols
• Enzyme activity profiling across temperature gradients and shear rates
• Environmental microbiology: water quality testing, biodegradation assays, and soil extract enrichment
• Pharmaceutical stability testing per ICH Q1A(R2) guidelines using defined agitation profiles
• Food safety labs conducting pathogen enrichment in buffered peptone water or selective broths

FAQ

Is the BSD-WX(F)2280 suitable for use with CO₂-controlled cultures?
No—the standard configuration lacks CO₂ regulation. However, the optional inert gas inlet can be adapted for nitrogen or argon purging; integration with external CO₂ controllers requires custom manifold design and validation.
Can the shaker maintain temperature uniformity with full load?
Yes—thermal uniformity (±1 °C) is specified under empty-chamber conditions per ISO 27667-1; loaded performance depends on vessel type, fill volume, and thermal mass, but empirical validation shows ≤±1.5 °C deviation across typical 2 L flask configurations at 37 °C.
Does the unit support GLP-compliant data integrity?
The base controller provides time-stamped parameter logging; full GLP compliance requires optional printer or PC interface plus site-specific validation of data capture, storage, and retrieval processes per ALCOA+ principles.
What maintenance is required for long-term reliability?
No scheduled lubrication is needed due to brushless motor and sealed bearing design. Routine tasks include wiping stainless-steel surfaces with 70% ethanol, inspecting door gasket integrity quarterly, and verifying calibration annually using NIST-traceable thermometers and tachometers.
Is firmware upgrade available?
Firmware updates are distributed by BOXUN upon request for registered customers; upgrades require connection to a Windows-based PC using proprietary configuration software and must be performed by authorized technical personnel.
