Overview
The Shanghai Shiping JDX-300 Classic Multi-Function Orbital Shaker is an engineered platform for precise, reproducible agitation of biological and chemical samples under ambient laboratory conditions. Designed around a robust single-shaft orbital drive mechanism—patented in China—the instrument delivers stable, low-vibration motion across its full speed range (50–300 rpm), with certified speed accuracy of ±1 rpm. Unlike belt-driven or eccentric cam systems, the monolithic shaft architecture eliminates mechanical backlash and harmonic resonance, resulting in silent operation and long-term mechanical integrity. The shaker operates without integrated heating or cooling; it is intended for use in temperature-controlled environments where sample thermal stability is maintained externally. Its 500 × 400 mm stainless-steel-coated aluminum platform supports standard flask configurations (e.g., 20 × 250 mL Erlenmeyer flasks) and accommodates custom clamping fixtures via standardized M4 threaded mounting points.
Key Features
- PID microprocessor control with large-character LCD display for intuitive real-time monitoring of speed, elapsed time, and remaining timer duration
- Eight-stage programmable sequence function: each segment independently defines target rpm and dwell time, enabling complex multi-phase incubation protocols (e.g., gradual ramp-up to culture saturation followed by deceleration)
- Soft-start circuitry prevents abrupt acceleration—minimizing liquid splashing and preserving cell viability during inoculation or sensitive suspension handling
- Dual independent safety layers: hardware-based over-speed detection with audible/visual alarm, plus thermally triggered motor cutoff to prevent coil damage during extended operation
- Electrical isolation safeguards: dedicated leakage current protection and overcurrent interrupters compliant with IEC 61010-1 Class II requirements, ensuring non-interference with adjacent instrumentation
- Memory retention for last-used parameters—including speed, timer setting, and program index—enabling seamless recovery after power interruption (auto-restart with user-configurable delay)
- Electrostatically applied ABS polymer housing: corrosion-resistant, non-conductive, and ergonomically contoured for benchtop integration and routine cleaning with ethanol or 70% isopropanol
Sample Compatibility & Compliance
The JDX-300 is validated for use with common microbiological, biochemical, and cell-culture vessels—including glass and polypropylene flasks (50–1000 mL), test tubes, deep-well plates, and custom bioreactor sleeves—when secured using compatible clamps or silicone matting. It meets general-purpose laboratory safety standards per IEC 61010-1 (2010) for electrical equipment used in measurement, control, and laboratory applications. While not certified for GLP/GMP-regulated workflows out-of-the-box, its parameter logging capability (via optional RS-232 or USB data export module) supports traceability requirements when integrated into validated SOPs. The unit complies with CE marking directives for electromagnetic compatibility (2014/30/EU) and low voltage (2014/35/EU), and its non-medical classification excludes regulatory oversight under FDA 21 CFR Part 820 or ISO 13485.
Software & Data Management
The embedded PID controller features no external software dependency: all configuration occurs via tactile membrane keys and on-device LCD feedback. For laboratories requiring audit trails, optional firmware-enabled serial communication (RS-232 or USB-to-serial) permits bidirectional parameter exchange with host PCs running LabVIEW, Python (PySerial), or custom SCADA interfaces. Time-stamped operational logs—including start/stop events, speed deviations exceeding ±2 rpm, and fault codes (E01 = overheat, E02 = over-speed)—can be exported as CSV files. When deployed in regulated environments, users may implement electronic record controls aligned with FDA 21 CFR Part 11 through third-party validation packages that enforce user authentication, electronic signatures, and immutable log archiving.
Applications
- Microbial growth kinetics: consistent aeration of E. coli, Bacillus subtilis, and yeast cultures in baffled flasks for OD600 calibration and bioprocess modeling
- Enzyme reaction profiling: uniform mixing during kinetic assays involving immobilized lipases or proteases in buffered aqueous media
- Cell suspension maintenance: gentle agitation of CHO or HEK293 cells in serum-free media to prevent sedimentation without shear-induced apoptosis
- Antibiotic susceptibility testing: timed oscillation protocols synchronized with automated plate readers for MIC endpoint determination
- Reagent homogenization: dispersion of nanoparticles, antibody conjugates, or viscous polymer solutions prior to HPLC or DLS analysis
- Environmental sample preparation: extraction of heavy metals from soil leachates or microplastic suspensions in EPA Method-compliant workflows
FAQ
Does the JDX-300 support temperature control?
No. The JDX-300 is a non-thermostatic orbital shaker. It must be operated inside an externally controlled environment (e.g., climate-stabilized lab room or within a temperature-regulated enclosure) if thermal consistency is required.
Can the shaker accommodate microtiter plates?
Yes—when used with an optional universal plate clamp kit (sold separately), the platform securely holds 96-well and 384-well plates for ELISA washing, bead-based assays, or high-throughput screening prep.
Is the 8-stage programming function retained after power loss?
Yes. All user-defined programs and the last-executed parameters are stored in non-volatile memory and restored automatically upon re-powering.
What maintenance is required for long-term reliability?
No scheduled lubrication is needed. The sealed imported bearings and brushless variable-frequency motor require only periodic inspection of platform leveling and cleaning of dust from ventilation grilles every 6 months.
How is speed calibration verified?
A factory-calibrated optical tachometer is included with each unit. Users may perform field verification using this device against the displayed rpm value at three points: 100 rpm, 200 rpm, and 300 rpm—deviation must remain within ±1 rpm per IEC 60751 Class B tolerance.
