Shanghai Shiping SPH-C3432 Basic High-Capacity Triple-Layer Orbital Shaker

Overview

The Shanghai Shiping SPH-C3432 Basic High-Capacity Triple-Layer Orbital Shaker is an industrial-grade platform engineered for reproducible, long-duration cultivation and mixing tasks in bioprocessing, microbiology, and biochemical R&D environments. Designed around a horizontal orbital motion principle—where samples undergo gentle yet uniform circular agitation at a fixed 50 mm diameter—the instrument ensures homogeneous suspension of microbial cultures, cell lines, and reagent mixtures without shear-induced damage. Its non-thermostatic architecture positions it specifically for ambient-temperature applications where precise thermal control is not required, but mechanical stability, load capacity, and operational continuity are critical. The triple-layer configuration—with six independently supported shelves—delivers scalable throughput for high-volume fermentation screening, seed train expansion, or parallel assay preparation across pharmaceutical QC labs, academic core facilities, and contract development organizations.

Key Features

• Robust Mechanical Architecture: Core structural elements—including the drive shaft housing, linkage arms, and base frame—are fabricated from ductile iron (ASTM A536 Grade 65-45-12), machined on CNC heavy-duty milling platforms to ensure dimensional repeatability and torsional rigidity under sustained 24/7 operation.
• Low-Friction Dynamic Balance Drive: Utilizes a patented parallelogram linkage mechanism that eliminates eccentric loading and minimizes bearing wear. This design achieves <1.5 dB(A) acoustic emission increase per 50 rpm increment and maintains rotational deviation ≤ ±0.3° across the full 30–250 rpm range.
• NSK-Grade Dual-Row Bearings: Factory-installed, pre-lubricated NSK 32012XJ double-row angular contact ball bearings rated for ≥100,000 hours L₁₀ life under nominal load conditions—validated per ISO 281:2007 standards.
• PID Microprocessor Control: Implements real-time environmental scanning logic to dynamically compensate for voltage fluctuation, load inertia variance, and ambient temperature drift—ensuring speed stability within ±1 rpm tolerance per setpoint.
• Triple-Layer Scalable Platform: Six reinforced stainless-steel shelves (1080 × 680 mm each) support heterogeneous vessel configurations simultaneously—enabling concurrent use of 250 mL Erlenmeyer flasks, 2 L Fernbach bottles, or custom bioreactor bags via adaptable clamping systems.
• Comprehensive Safety Protocol Stack: Integrates three-tiered protection: (1) personnel-level interlocks (door-open cutoff, emergency stop), (2) sample-level safeguards (overspeed shutdown, imbalance detection), and (3) equipment-level redundancy (dual independent overcurrent relays, grounded leakage circuit interrupter).

Sample Compatibility & Compliance

The SPH-C3432 accommodates standard microbiological and bioprocess vessels—including glass and PETG Erlenmeyer flasks (250–2000 mL), baffled culture bottles, and sterile single-use bioreactor bags mounted on rigid carriers. Its open-chamber design complies with ISO 13485:2016 requirements for equipment used in medical device manufacturing support processes. While not certified for GMP cleanroom deployment (Class ISO 5–8), it meets IEC 61000-6-2/6-4 electromagnetic compatibility standards and carries CE marking per Machinery Directive 2006/42/EC. For GLP-regulated environments, optional audit-trail firmware (v3.2+) supports 21 CFR Part 11-compliant electronic records when paired with validated networked data loggers.

Software & Data Management

Local operation is managed via an embedded 4.3-inch TFT LCD interface with tactile membrane keys and real-time graphical feedback of speed, elapsed time, and remaining cycle duration. The onboard controller supports eight-segment programmable profiles—each configurable for ramp rate, dwell time, acceleration/deceleration slope, and end-state behavior (hold, stop, or auto-reverse). All parameter changes are timestamped and stored in non-volatile memory with cyclic overwrite protection. Optional RS-485 Modbus RTU output enables integration into SCADA or MES platforms for centralized batch tracking. No proprietary cloud service or vendor-hosted software is required; raw log files export via USB 2.0 as CSV-compatible ASCII text with ISO 8601 timestamps.

Applications

• Bacterial and yeast strain propagation for inoculum preparation in upstream bioprocess development
• Enzyme kinetics assays requiring consistent oxygen transfer and suspension homogeneity
• Hybridization buffer equilibration in molecular diagnostics workflow prep
• Antibiotic susceptibility testing using broth microdilution formats
• Protein solubilization and ligand-binding equilibrium studies in structural biology pipelines
• Environmental microbiology sampling—e.g., BOD incubation, coliform enrichment, and wastewater biomass acclimation
• Food safety validation protocols including pathogen recovery and toxin extraction optimization

FAQ

Is the SPH-C3432 suitable for use in a Class 10,000 cleanroom environment?
No—its open-air cabinet design lacks HEPA filtration, static-dissipative finishes, or ISO 14644-1 particulate containment features. It is intended for controlled but non-classified lab or pilot-plant spaces.
Can the shaker maintain speed accuracy when loaded with 90 × 2 L flasks?
Yes—rated torque output (≥12.8 N·m continuous) and inertia-compensated PID control ensure ≤±1.2 rpm deviation at 250 rpm under maximum specified load (1,620 kg total mass).
Does the unit support external temperature monitoring integration?
Not natively—the system operates at ambient temperature only. However, third-party PT100 probes can be mounted externally and logged via the RS-485 port using user-defined Modbus register mapping.
What maintenance intervals are recommended for the NSK bearings?
Per manufacturer specifications: no scheduled lubrication or replacement required within first 100,000 operational hours (≈11.4 years at 24/7 duty cycle); visual inspection every 12 months is advised.
Is firmware upgrade capability available post-purchase?
Yes—field-upgradable via USB flash drive using signed binary images distributed through Shanghai Shiping’s authorized technical support portal (access requires valid serial-number authentication).
