Shanghai Shiping SPH-310F Universal Orbital Shaker

Overview

The Shanghai Shiping SPH-310F Universal Orbital Shaker is an entry-level, high-reliability benchtop shaker engineered for consistent orbital motion in microbiological culturing, cell suspension, reagent mixing, and general laboratory sample agitation. It operates on the principle of controlled eccentric rotation—where a motor-driven cam mechanism induces smooth, circular horizontal displacement of the platform—ensuring uniform energy transfer across vessel arrays without vortex formation or splashing. Unlike incubator shakers or refrigerated models, the SPH-310F is designed strictly for ambient-temperature applications, making it ideal for laboratories where thermal stability is maintained externally (e.g., climate-controlled rooms or laminar flow cabinets). Its robust mechanical architecture—including NSK double-row precision bearings, quenched-and-tempered 45# carbon steel shafts, and corrosion-inert ABS housing—ensures long-term operational integrity under daily QC/QA or teaching-lab workloads.

Key Features

• PID microprocessor control with environmental scanning chip ensures stable speed regulation across load variations and line-voltage fluctuations.
• LCD interface with real-time display of setpoint and actual rpm, elapsed time, and remaining timer duration.
• Eight-segment programmable protocol storage enables repeatable multi-step agitation sequences (e.g., ramp-up → hold → ramp-down), supporting standardized SOP execution.
• Automatic power-failure recovery retains last-used parameters and resumes operation upon grid restoration—critical for unattended overnight cultures.
• Single-platform design (550 × 400 mm) accommodates diverse vessel configurations: up to twelve 1000 mL Erlenmeyer flasks, fifteen 500 mL bottles, or twenty-four 250 mL tubes—optimized for scalability in microbial fermentation or antibody production workflows.
• Mechanically balanced single-axis drive system minimizes vibration transmission to adjacent instruments and reduces structural fatigue over extended duty cycles.

Sample Compatibility & Compliance

The SPH-310F supports standard glass and plastic labware including conical flasks, centrifuge tubes, deep-well plates, and media bottles. Its 25 mm orbital diameter provides sufficient shear for aerobic microbial growth while avoiding excessive foaming or cell lysis in sensitive mammalian suspensions. Though not certified for GMP or ISO 13485 environments, its construction adheres to IEC 61010-1 safety standards for laboratory electrical equipment. The ABS housing meets UL 94 V-0 flammability rating, and the absence of internal temperature control eliminates calibration requirements under ASTM E1227 or USP analytical instrument qualification protocols—reducing validation burden for non-regulated research or educational use.

Software & Data Management

The SPH-310F operates as a standalone hardware device with no external software dependency. All operational data—including setpoints, runtime logs, and power-cycle timestamps—are retained locally via non-volatile memory. While it lacks Ethernet/USB connectivity or remote monitoring capability, its eight-segment programmability and parameter memory align with basic GLP documentation needs: users can record protocol IDs, operator initials, and batch numbers manually alongside run logs. For labs implementing 21 CFR Part 11 compliance, external time-stamped video logging or integrated LIMS interfaces may be deployed to capture start/stop events and parameter changes.

Applications

• Microbial culture expansion (E. coli, yeast, Bacillus spp.) in aerobic liquid media.
• Suspension-based cell line maintenance (e.g., CHO, HEK293) prior to transfection or harvest.
• Antibody solubilization and antigen-antibody binding kinetics studies requiring gentle, continuous mixing.
• Soil/water extraction protocols for environmental microbiology and nutrient leaching assays.
• Reagent homogenization in clinical chemistry and immunoassay preparation workflows.
• Undergraduate and graduate teaching labs emphasizing reproducible agitation parameters and experimental design fundamentals.

FAQ

Does the SPH-310F support temperature control?
No. It is an ambient-only shaker with no integrated heating or cooling elements. Users must maintain required temperature externally.
Can it operate continuously for more than 24 hours?
Yes—the 0–999.59 hour timer supports uninterrupted runs exceeding 41 days; however, routine mechanical inspection is recommended after 168 hours of cumulative operation.
Is the platform compatible with microplate carriers or clamps?
The flat, non-perforated surface accepts third-party universal plate holders and flask clamps, provided total mass remains within 12 kg static load limit.
What maintenance is required?
Annual lubrication of the drive shaft and visual inspection of the NSK bearing seal are advised. No firmware updates or calibration procedures apply.
Does it meet CE or RoHS directives?
As a domestically marketed instrument, it complies with China’s CCC certification requirements; CE/RoHS declarations are not issued for this model variant.
