Shanghai Shiping SPH-C3222 Floor-Standing Orbital Shaker

Overview

The Shanghai Shiping SPH-C3222 Floor-Standing Orbital Shaker is an engineered solution for high-capacity, long-duration incubation and mixing applications in regulated life science laboratories. Utilizing a true orbital motion profile—defined by a consistent 50 mm circular displacement—the instrument ensures uniform suspension of microbial cultures, mammalian cells, enzymatic reaction mixtures, and immunoassay plates without vortexing or shear-induced cell damage. Its single-axis parallel-linkage balanced drive mechanism eliminates mechanical backlash and rotational inertia asymmetry, enabling stable operation at speeds ranging from 30 to 300 rpm with ±1 rpm repeatability over extended cycles. Designed for ambient-temperature environments only, the shaker integrates robust thermal management via natural convection airflow channels within its structural chassis, minimizing heat accumulation during multi-day runs. With a net weight of 476 kg and a rigid ductile cast iron core architecture, the unit delivers exceptional vibration isolation and platform stability—even when fully loaded with up to 192 × 250 mL flasks or 80 × 1000 mL bottles.

Key Features

• Double-tier shaking platform (2 independently usable shelves), each measuring 1108 × 740 mm, supporting scalable throughput across diverse vessel formats.
• PID-controlled microprocessor system with LCD interface enables intuitive parameter navigation—no specialized training required for speed, timer, or auto-restart configuration.
• NSK-sourced double-row roller bearings rated for ≥100,000 hours of continuous operation under nominal load conditions, ensuring mechanical longevity and minimal maintenance intervals.
• Three-layer safety architecture: personnel protection (leakage and over-current cutoff), sample integrity assurance (independent over-speed detection with dual-mode alarm), and equipment safeguarding (timer monitoring and power-failure recovery logic).
• Structural frame fabricated from precision-machined ductile cast iron and cold-rolled steel, with quenched-and-tempered 45# carbon steel drive shafts (220–250 HBW hardness) for torsional rigidity and fatigue resistance.
• Low-noise operation (<45 dB[A] at 1 m distance) achieved through frictionless dynamic balancing and optimized gear-train kinematics—critical for shared lab environments and noise-sensitive facilities.

Sample Compatibility & Compliance

The SPH-C3222 accommodates standard laboratory vessels including Erlenmeyer flasks (up to 1000 mL), culture bottles, deep-well plates, and custom bioreactor sleeves. Its large platform surface allows flexible layout configurations for heterogeneous sample sets—ideal for parallel fermentation optimization, dose-response screening, or multi-condition enzyme kinetics studies. The system complies with mechanical safety requirements outlined in IEC 61010-1:2010 and supports laboratory quality systems aligned with ISO/IEC 17025, FDA 21 CFR Part 11 (when paired with validated LIMS integration), and EU Annex 11 data integrity principles. While not temperature-controlled, its ambient-only design meets ASTM E2500-13 guidance for non-climate-regulated mixing devices used in upstream process development.

Software & Data Management

The embedded PID controller provides local parameter logging—including runtime, setpoint history, and alarm events—with non-volatile memory retention for up to 10,000 operational cycles. Though lacking Ethernet or USB connectivity, the system supports audit-ready documentation through synchronized external timestamping via RS-232-compatible serial output (optional adapter). All user-modifiable parameters—including speed, timer duration, and restart behavior—are stored in EEPROM with write-protection logic to prevent accidental overwrite. For GxP environments, the device can be qualified using IQ/OQ protocols referencing manufacturer-supplied mechanical performance data and third-party vibration spectrum analysis reports.

Applications

This shaker serves as a foundational tool in microbiology (aerobic bacterial propagation), molecular biology (plasmid amplification, hybridization kinetics), biopharmaceutical process development (cell line expansion, media optimization), food safety testing (pathogen enrichment), and environmental microbiology (BOD assays, wastewater inoculation). Its dual-platform architecture enables side-by-side comparison of culture conditions—for instance, evaluating two carbon sources in parallel fermentations or comparing transfection efficiencies across multiple plasmid constructs. The high-load capacity and low-drift speed control make it particularly suitable for scale-down modeling of benchtop bioreactors.

FAQ

Is the SPH-C3222 suitable for use in ISO Class 5 cleanrooms?
Yes—its sealed drive housing, absence of internal cooling fans, and static-dissipative powder-coated finish meet particulate generation thresholds for controlled environments when installed with appropriate air filtration.
Can the timer be programmed for multi-step sequences?
No—the timer supports single-interval countdown only; however, eight-segment curve programming is available via optional firmware upgrade (SPH-C3222-PRO variant).
What is the maximum allowable imbalance tolerance per shelf?
The system tolerates ≤5% mass asymmetry across the platform plane without inducing measurable deviation in orbit geometry or speed stability.
Does the unit include calibration documentation?
A factory-issued Certificate of Conformance (CoC) with speed verification traceable to NIM (National Institute of Metrology, China) is provided; full metrological calibration requires third-party service.
Is remote monitoring supported?
Not natively—but analog 0–10 V output signals for speed and status are accessible via terminal block for integration into building management or SCADA systems.
