Shanghai Shiping SPH-110X48 Horizontal Reciprocating Water Bath Shaker

Overview

The Shanghai Shiping SPH-110X48 Horizontal Reciprocating Water Bath Shaker is an engineered platform for precise temperature-controlled agitation of liquid samples in life science and bioprocess laboratories. Designed around the principle of reciprocating linear motion—where a single-axis balanced drive system generates consistent back-and-forth oscillation—the instrument ensures uniform heat transfer and mechanical stimulation across the entire working chamber. Unlike orbital or rotary shakers, this configuration minimizes centrifugal force effects while maximizing shear homogeneity, making it especially suitable for applications requiring gentle yet reproducible mixing under controlled thermal conditions. Its water-jacketed bath design provides superior thermal stability and uniformity compared to air-jacketed alternatives, critical for sensitive biological assays such as microbial culture propagation, enzymatic reaction kinetics, hybridization protocols, and tissue dissociation workflows.

Key Features

• Single-axis parallel-linkage balanced drive mechanism: Eliminates mechanical friction and vibration-induced drift; enables low-noise (<55 dB), energy-efficient continuous operation over extended durations.
• High-integrity 316L stainless steel construction: Entire inner chamber, platform, and clamping components fabricated from medical-grade 316L stainless steel—resistant to chlorides, acids, and alkaline solutions, compliant with ISO 13485-informed cleanability standards and GMP facility requirements.
• PID-based microprocessor control with LCD interface: Real-time environmental scanning algorithm maintains setpoint accuracy within ±0.1 °C at steady state and ±0.2 °C uniformity across the chamber volume.
• Eight-segment programmable curve functionality: Supports complex multi-step protocols including ramp-hold-cool cycles, enabling automated simulation of physiological or process-relevant thermal-agitation profiles.
• Triple-layer safety architecture: Includes independent overtemperature cutoff (mechanical backup), overspeed detection with audible/visual alarm, sensor fault diagnostics, earth-leakage protection, and power-failure recovery with parameter retention.
• NSK double-row precision bearings: Rated for ≥100,000 hours of continuous service life under nominal load; integrated with hardened 45# carbon steel drive shaft (220–250 HBW) for long-term dimensional stability.

Sample Compatibility & Compliance

The SPH-110X48 accommodates standard laboratory glassware configurations—including up to 48 × 250 mL Erlenmeyer flasks, 35 × 500 mL vessels, or 20 × 1000 mL containers—secured via spring-loaded or bottle-clamp platforms. Its large-format platform (780 × 586 mm) supports custom fixture integration for specialized bioreactor vessels or multi-well plate holders. The unit complies with IEC 61010-1:2010 for electrical safety in laboratory equipment and meets electromagnetic compatibility (EMC) requirements per EN 61326-1. While not certified to FDA 21 CFR Part 11 out-of-the-box, its parameter encryption, audit trail-capable logging (via optional RS485/USB export), and password-protected configuration align with GLP/GMP documentation practices when deployed with validated SOPs.

Software & Data Management

The embedded PID controller stores up to 10 user-defined protocols with full parameter encryption and one-touch factory reset. All operational events—including temperature deviations, speed fluctuations, timer completions, and alarm triggers—are timestamped and retained in non-volatile memory. Optional data logging modules support CSV export via USB or serial interface for traceability in quality-controlled environments. When integrated into networked lab infrastructure, the shaker’s analog/digital I/O ports allow synchronization with external incubators, spectrophotometers, or LIMS systems—facilitating end-to-end process monitoring in regulated pharmaceutical or clinical research settings.

Applications

This shaker serves core functions across academic, industrial, and regulatory laboratories: bacterial and yeast culture expansion under defined thermal-aeration conditions; immunoassay plate washing and antigen-antibody binding enhancement; DNA/RNA hybridization optimization; enzyme activity profiling across temperature gradients; protein solubilization and refolding studies; fermentation seed train preparation; and environmental sample extraction (e.g., soil leaching, water toxicity testing). Its stable thermal performance and mechanical repeatability make it suitable for method validation per USP , ASTM E2500, and ISO/IEC 17025-compliant calibration frameworks.

FAQ

What is the maximum load capacity for uniform temperature distribution?
Uniformity specifications (±0.2 °C) are validated at full load with standard 250 mL flasks evenly distributed across the platform.
Can the unit operate continuously for 72+ hours without intervention?
Yes—designed for unattended long-duration runs; thermal and mechanical subsystems include redundant safeguards for uninterrupted operation.
Is calibration documentation provided with shipment?
Factory calibration certificates for temperature and speed sensors are included; on-site IQ/OQ/PQ validation support is available upon request.
Does the shaker support external communication protocols?
Standard RS485 Modbus RTU interface enables integration with SCADA or building management systems; optional Ethernet gateway available.
How is maintenance access designed for routine servicing?
Front-access service panel allows tool-free removal of motor housing, water pump, and heater elements—minimizing downtime during preventive maintenance.
