Shanghai Shiping SPH-300D Benchtop Single-Layer Orbital Shaker

Overview

The Shanghai Shiping SPH-300D is a benchtop single-layer orbital shaker engineered for reproducible, low-maintenance agitation of culture vessels in ambient-temperature laboratory environments. It operates on the principle of orbital motion—where the platform rotates around a fixed central axis with a defined circular trajectory (Φ50 mm)—to generate uniform, gentle mixing ideal for microbial growth, cell suspension, solubilization, and reagent homogenization. Unlike incubated shakers, the SPH-300D is specifically designed for integration into externally controlled temperature-stable rooms or walk-in environmental chambers, enabling high-throughput parallel processing under tightly regulated thermal conditions. Its robust mechanical architecture, including a patented single-axis balanced drive system and brushless frequency-controlled motor, ensures long-term operational stability, minimal vibration transmission to adjacent equipment, and acoustic performance suitable for shared lab spaces.

Key Features

• Eight-segment programmable control: Each segment independently defines speed (50–300 rpm) and duration (up to 500 hours), supporting complex multi-phase protocols such as adaptive inoculation, staged induction, or gradient-based assay preparation.
• Precision speed regulation: Microprocessor-based PID feedback loop maintains rotational accuracy within ±1 rpm—even under variable load conditions—ensuring consistent shear stress across flask sizes from 50 mL to 5000 mL.
• Intelligent operational safeguards: Independent hardware-level protections include over-speed cutoff, thermal shutdown for motor overheating, leakage current detection, and dual-stage over-current interruption—each isolated to prevent cascading failure.
• Soft-start circuitry: Gradual ramp-up from standstill eliminates sudden torque surges, minimizing liquid splashing and preserving integrity of sensitive biological samples or viscous media.
• Power-efficient design: 70 W nominal power draw (SPH-300D) enables continuous operation without significant heat generation or facility load impact—critical for clustered deployment in centralized incubation suites.
• Durable mechanical construction: Load-bearing chassis fabricated from cold-rolled steel, structural angles, and cast iron; wear-critical drivetrain components made from chromium alloy and paired with imported high-tolerance ball bearings.
• User memory retention: Last-used parameters—including speed, timing, and program sequence—are retained after power loss or cycle completion, with automatic recovery upon restart (including “power-fail resume” functionality).

Sample Compatibility & Compliance

The SPH-300D accommodates standard Erlenmeyer flasks (50–5000 mL) via interchangeable universal clamps. Maximum configuration supports up to 96 × 250 mL flasks, 24 × 500 mL flasks, or 16 × 1000 mL flasks on its 680 × 500 mm platform. While the unit itself provides no active temperature regulation, its ambient-only specification aligns with ISO 13485 and FDA 21 CFR Part 11 requirements for ancillary equipment used in GMP-compliant bioprocess development—provided it operates within validated environmental chambers meeting ASTM E145 or ICH Q5C thermal uniformity criteria. The device’s electrical safety architecture complies with IEC 61010-1:2010 for laboratory equipment, including reinforced insulation, double-pole switching, and earth-leakage current ≤0.75 mA at rated voltage.

Software & Data Management

The SPH-300D features an embedded microcontroller with LCD interface and tactile keypad navigation—designed for standalone use without external software dependencies. All programming, real-time monitoring (current speed, elapsed time, remaining time), and alarm status are accessible locally. Though it lacks Ethernet/USB connectivity or cloud integration, its parameter memory and clock-synchronized timing support ALCOA+ data integrity principles when operated under documented SOPs: all user-defined programs can be logged manually in lab notebooks with traceable timestamps; audit trails are maintained via physical logbooks per GLP guidelines. Optional calibration certificates (traceable to NIST standards) are available for speed verification at three points (100/200/300 rpm) to satisfy internal QA requirements.

Applications

• Microbial strain screening and fermentation optimization in R&D bioreactor workflows
• Pre-incubation of bacterial or yeast cultures prior to inoculation into larger-scale systems
• Suspension culture maintenance for insect or mammalian cells requiring gentle agitation
• Buffer equilibration, antigen-antibody mixing, and ELISA plate coating steps
• Extraction protocol standardization (e.g., nucleic acid or protein isolation from solid matrices)
• Quality control testing of media sterility and growth support capacity

FAQ

Does the SPH-300D include heating or cooling capability?
No. It is an ambient-only orbital shaker intended for use inside externally temperature-controlled environments—such as climate-stabilized rooms or integrated incubation cabinets.

What is the maximum flask volume supported on the SPH-300D platform?
Up to 5000 mL flasks may be accommodated using optional heavy-duty clamps; however, optimal performance is achieved with loads between 250 mL and 2000 mL due to moment-arm constraints and platform inertia.

Is the SPH-300D compliant with FDA 21 CFR Part 11 for electronic records?
As a non-networked, non-auditable device with no electronic record generation, it falls outside Part 11 scope—but remains suitable for use in Part 11-regulated environments when deployed per written procedures and manual documentation practices.

Can the SPH-300D be stacked or mounted in multi-tier configurations?
No. It is designed for single-unit benchtop placement only. Structural rigidity and airflow requirements preclude vertical stacking; adjacent units must maintain ≥10 cm clearance for thermal dissipation.

What maintenance is required for long-term reliability?
Annual inspection of drive belt tension (if applicable), bearing lubrication check, and verification of clamp integrity are recommended. The brushless motor requires no routine servicing; firmware updates are not supported.
