Shanghai Shiping SPH-2112D Vertical Dual-Door Double-Layer Orbital Incubator Shaker with 50 mm Amplitude

Overview

The Shanghai Shiping SPH-2112D is a vertically oriented, dual-door, double-layer orbital incubator shaker engineered for high-throughput microbial culture, cell suspension expansion, and biochemical reaction optimization in academic research laboratories, biopharmaceutical process development, and QC/QA environments. Its core operational principle combines precise temperature-controlled convection with uniform orbital motion (50 mm amplitude, 30–300 rpm), enabling consistent oxygen transfer and suspension homogeneity across large-volume liquid cultures. The unit integrates a microprocessor-based PID control system with environmental scanning capability to continuously monitor and dynamically adjust heating, cooling, and motor output—ensuring stable thermal performance (±0.2 °C stability, ≤±1 °C uniformity at 37 °C) and mechanical reproducibility (±1 rpm speed accuracy). Designed for continuous operation under GLP-compliant workflows, the SPH-2112D meets structural and functional requirements aligned with ISO 13485 design controls and supports audit-ready documentation via its parameter memory, encryption lock, and power-failure recovery functions.

Key Features

• Vertical dual-layer architecture with independent dual-door access—maximizes floor space efficiency while accommodating up to 639 L total chamber volume and two independently configurable 920 × 520 mm stainless steel shelves.
• Single-axis balanced drive mechanism minimizes mechanical vibration transmission and acoustic emission (<55 dB[A] at 1 m), eliminating resonance-induced sample disturbance during sensitive long-term cultivations.
• PID-controlled refrigeration-heating system using an imported R134a compressor and high-capacity 1100 W heater ensures rapid thermal equilibration and tight setpoint adherence across the full 4–60 °C operating range.
• LCD backlit display with dual-parameter view (setpoint vs. real-time values) provides immediate visibility of temperature, speed, time, and alarm status; all operational parameters are password-locked to prevent unauthorized modification.
• Comprehensive safety architecture includes redundant over-temperature cutoffs (independent mechanical thermostat + electronic sensor), motor overheat detection, leakage current protection, and door-interlocked power disengagement.
• Eight-segment programmable curve functionality enables complex multi-step protocols (e.g., ramp-hold-cool cycles) without external controllers—critical for adaptive fermentation or synchronized induction studies.

Sample Compatibility & Compliance

The SPH-2112D accommodates standard laboratory glassware and disposable bioreactors ranging from 50 mL tubes to 2000 mL baffled flasks, with standardized clamping configurations supporting Erlenmeyer flasks, Fernbach flasks, and square-section culture vessels. Its fully welded, mirror-finish 304 stainless steel interior—with zero dead-angle radiused corners—meets cleanroom-compatible surface finish requirements (Ra ≤ 0.8 µm) and resists corrosion from repeated sterilant exposure (e.g., 70% ethanol, hydrogen peroxide vapor, or sodium hypochlorite solutions). The unit complies with IEC 61010-1:2010 for laboratory equipment safety and incorporates electromagnetic compatibility (EMC) shielding per EN 61326-1. While not certified for GMP manufacturing suites, its design supports 21 CFR Part 11–aligned data integrity practices when integrated with validated third-party logging software.

Software & Data Management

The embedded controller stores up to 10 user-defined protocols with timestamped execution logs, including start/stop times, setpoint deviations, and alarm events—all retained after power interruption. Parameter encryption prevents accidental changes during shared-lab use, and “one-click factory reset” simplifies revalidation between experimental campaigns. Though the device lacks native Ethernet or USB host interfaces, analog voltage outputs (0–5 V) for temperature and speed enable connection to external DAQ systems compliant with ASTM E2500-13 for equipment qualification. All calibration points (temperature sensor offset, speed tachometer gain) are field-adjustable via service mode, supporting routine IQ/OQ documentation per ISO/IEC 17025 guidelines.

Applications

• High-density bacterial and yeast cultivation for plasmid amplification, protein expression, and metabolic engineering strain screening.
• Mammalian suspension cell propagation in serum-free media for monoclonal antibody production and viral vector manufacturing.
• Enzymatic assay development requiring controlled agitation and thermostatic precision (e.g., lipase kinetics, cellulase hydrolysis).
• Environmental microbiology studies involving soil slurry enrichment or wastewater biomass acclimation under aerobic oscillatory conditions.
• Stability testing of biologics formulations under accelerated temperature-agitation stress per ICH Q5C recommendations.

FAQ

Does the SPH-2112D support remote monitoring or network connectivity?
No—the unit operates as a standalone instrument with local PID control and does not include Wi-Fi, Ethernet, or Bluetooth modules. Integration with lab-wide monitoring systems requires external analog signal acquisition.
What is the maximum flask loading configuration for optimal oxygen transfer?
For 2000 mL baffled flasks, the recommended fill volume is ≤30% (600 mL) per vessel; total loading should not exceed 20% of chamber volume to maintain airflow integrity and thermal uniformity.
Can the unit operate continuously at 4 °C with full-speed agitation?
Yes—the compressor and motor are rated for uninterrupted operation across the entire temperature and speed range; however, ambient room temperature must remain between 5–35 °C per specification.
Is the stainless steel chamber electropolished or passivated?
The interior uses mechanically polished 304 stainless steel (Ra ≤ 0.8 µm); electropolishing or nitric acid passivation is not performed at the factory but may be applied post-installation per ASTM A967.
Are validation documents (IQ/OQ templates) provided with the instrument?
Shanghai Shiping supplies basic technical specifications and electrical safety certificates; site-specific IQ/OQ protocols must be developed by the end-user’s qualified validation team in accordance with ISO 13485 or FDA guidance.
