Shanghai Shiping SPH-3112 Standard Dual-Deck Small-Capacity Orbital Shaker

Overview

The Shanghai Shiping SPH-3112 is a robust, dual-deck orbital shaker engineered for high-throughput biological culture and fermentation applications in controlled ambient environments. Designed for integration into dedicated temperature-stabilized rooms—such as cleanroom-adjacent incubation suites or GMP-compliant bioprocess development labs—the SPH-3112 delivers precise, reproducible orbital motion via a patented single-shaft drive mechanism. Unlike conventional eccentric-drive shakers prone to mechanical drift and vibration coupling, this architecture ensures uniform amplitude transmission across both decks with minimal noise (<55 dB(A) at 1 m), reduced harmonic resonance, and long-term mechanical stability. Its 50 mm circular orbit meets ISO 20949:2021 recommendations for microbial suspension homogeneity in Erlenmeyer flasks and baffled bioreactors up to 1 L capacity. The system operates exclusively at ambient temperature and is not equipped with internal heating or refrigeration; therefore, it requires external environmental control per ASTM E145-22 Class II chamber specifications when used for thermosensitive cultures.

Key Features

• Patented single-shaft orbital drive system—eliminates gear backlash and torsional misalignment, ensuring consistent amplitude and extended service life (>50,000 h MTBF)
• Eight-segment programmable controller with independent time/speed profiles per segment, supporting complex multi-phase culture protocols (e.g., lag-phase induction followed by exponential growth acceleration)
• PID microprocessor-based regulation with ±1 rpm frequency accuracy—validated per ISO/IEC 17025 calibration traceability protocols
• Slow-start circuitry prevents liquid splashing during initiation, critical for maintaining sterility in low-volume inocula (e.g., 25–100 mL cultures)
• Dual independent decks (840 × 620 mm each) with reinforced cold-rolled steel frames and precision-machined mounting rails—compatible with standardized flask clamps (250 mL, 500 mL, 1000 mL)
• Comprehensive safety architecture: isolated ground-fault interrupter (GFCI), thermal cut-off at motor windings, real-time over-speed detection with audible/visual alert, and non-volatile parameter memory with auto-recovery after power interruption
• Electrostatically applied corrosion-resistant polyester coating on structural chassis—meets ISO 9223 C3 corrosion category for laboratory indoor use

Sample Compatibility & Compliance

The SPH-3112 accommodates standard microbiological vessels including conical flasks (250–1000 mL), baffled culture bottles, and stacked multi-well plates (when mounted on custom adapter trays). Flask retention uses stainless-steel spring-loaded clamps conforming to DIN 12571:2020 dimensional tolerances. While the unit itself does not carry CE, UL, or CSA certification due to its ambient-only operation and domestic manufacturing origin, its electrical safety subsystems—including IEC 61000-4-5 surge immunity and IEC 60335-1 leakage current limits (<0.75 mA)—are designed to support integration into ISO 13485-certified medical device manufacturing facilities and GLP-compliant preclinical labs. It supports audit-ready operation when paired with external environmental monitoring systems compliant with FDA 21 CFR Part 11 data integrity requirements.

Software & Data Management

The SPH-3112 features an embedded LCD interface with intuitive membrane keypad navigation—no external PC or proprietary software required. All operational parameters (speed, duration, program sequence, real-time elapsed time) are displayed simultaneously. Eight user-defined programs can be stored locally with timestamped execution logs retained in non-volatile memory for ≥12 months. Optional RS-485 Modbus RTU output (available on SPH-3222/3332 variants) enables integration with SCADA platforms or LIMS systems for automated batch record generation. No cloud connectivity or remote access functionality is included, preserving data sovereignty in regulated environments.

Applications

• High-density microbial strain screening in pharmaceutical R&D (E. coli, P. pastoris, B. subtilis)
• Seed train expansion for mammalian cell culture processes prior to bioreactor inoculation
• Enzyme production optimization under aerobic shake-flask conditions
• Antibiotic susceptibility testing using broth microdilution formats
• Soil microbiome enrichment studies requiring prolonged agitation without thermal perturbation
• Quality control of raw materials (e.g., yeast extract, peptones) via growth-support validation

FAQ

Does the SPH-3112 include temperature control?
No. It operates at ambient temperature only and must be installed in externally climate-controlled spaces meeting ISO 14644-1 Class 7 or better for sensitive applications.
Can the two decks operate at different speeds simultaneously?
No. Both decks are mechanically coupled and run at identical speed and timing parameters per program segment.
What is the maximum flask size supported per clamp position?
1000 mL Erlenmeyer flasks with standard 100 mm neck diameter; clamp load capacity is rated to 3 kg per position.
Is calibration documentation provided with shipment?
A factory-issued performance verification report (including amplitude verification at 100/200/300 rpm and timer accuracy test) is included; full ISO/IEC 17025 calibration certificates require third-party engagement.
What maintenance is required for long-term reliability?
Annual inspection of drive belt tension (if applicable), bearing lubrication check, and verification of clamp torque specification (12 N·m)—no routine motor servicing needed due to brushless design.
