Labotery SYWF-60 Water Bath Orbital Shaker

Overview

The Labotery SYWF-60 Water Bath Orbital Shaker is an engineered platform for precise temperature-controlled agitation of liquid samples in life science, microbiology, and biochemical laboratories. It operates on the principle of orbital shaking—generating a consistent circular motion with a fixed 20 mm diameter orbit—while maintaining uniform thermal conditions across the entire water bath volume. Unlike air-jacketed incubator shakers, this unit employs direct liquid-phase thermal coupling via a fully submersible stainless steel 304 water bath, ensuring superior temperature homogeneity (±0.2 °C at 37 °C under 100 rpm load) and minimal thermal lag during ramping or setpoint changes. Its ambient-to-99.9 °C operating range supports applications ranging from low-temperature enzyme kinetics to high-temperature bacterial culture enrichment. The integrated fuzzy PID microprocessor control algorithm reduces overshoot, accelerates stabilization time, and delivers 0.1 °C temperature resolution—critical for reproducible cell growth, solubility studies, and immunoassay incubation protocols.

Key Features

• Fuzzy PID digital temperature control system with real-time feedback loop, achieving faster equilibrium and tighter thermal regulation than conventional PID implementations
• Isolated heating element design—electric heater physically separated from water bath chamber—to eliminate electrical leakage risk and enhance operator safety
• Single robust 304 stainless steel tray (340 × 470 mm), rated for up to 1000 mL × 6 flasks or 250 mL × 15 tubes; quick-release mounting enables tool-free tray removal for cleaning or configuration change
• Brushless AC servo motor (220 V input) delivering stable speed control from 20 to 200 rpm with ±1 rpm accuracy and low acoustic emission (<55 dB(A) at 150 rpm)
• Integrated safety interlocks: automatic power cutoff upon low water level detection, independent overtemperature alarm circuit, and non-volatile memory retention for timer and setpoint settings after power interruption
• Front-panel backlit LCD interface with intuitive menu navigation; side-mounted drain valve simplifies routine bath maintenance and fluid replacement
• Structural frame engineered for high load-bearing capacity and mechanical damping—supports full-load operation without resonance or vibration transmission to adjacent benchtop equipment

Sample Compatibility & Compliance

The SYWF-60 accommodates standard laboratory vessels including Erlenmeyer flasks (100–1000 mL), test tubes, centrifuge tubes, and multi-well plates mounted on universal clamps or custom adapters. Its 304 stainless steel bath and tray resist corrosion from aqueous buffers, saline solutions, and mild organic solvents used in molecular biology workflows. While not certified for IEC 61000-6-3 EMC or UL 61010-1 out-of-the-box, the device meets fundamental electrical safety requirements for Class I laboratory equipment per GB 4793.1 (Chinese national equivalent to IEC 61010-1). When operated within validated SOPs—including regular calibration of temperature and speed sensors—the instrument supports GLP-compliant data generation for internal R&D use. For regulated environments requiring audit trails, external logging via RS-232 or optional USB interface (firmware-dependent) may be implemented alongside lab-specific documentation practices.

Software & Data Management

The SYWF-60 operates as a standalone instrument with no embedded PC-based software. All parameters—including temperature setpoint, oscillation speed, and timer duration—are configured directly via the front-panel interface. Non-volatile EEPROM retains user-defined settings through power cycles, preserving experimental continuity. For integration into networked lab infrastructures, optional serial (RS-232) output allows connection to third-party data acquisition systems or LIMS platforms using ASCII command protocols (e.g., “TEMP?”, “SPEED=120”). No proprietary drivers or cloud services are required. This architecture aligns with ISO/IEC 17025 Clause 5.5.2 regarding equipment traceability and minimizes cybersecurity exposure inherent in connected instruments. Calibration records, maintenance logs, and performance verification reports (e.g., temperature uniformity mapping per ASTM E2233) should be maintained locally by the end user per institutional quality policy.

Applications

• Microbial culture expansion in liquid media (E. coli, yeast, mammalian suspension cells) under controlled thermal and agitation conditions
• Enzyme activity assays requiring precise incubation temperatures and homogeneous mixing to prevent sedimentation or localized denaturation
• DNA/RNA hybridization steps in blotting protocols where consistent temperature and gentle agitation improve probe binding efficiency
• Solubility and dissolution testing of pharmaceutical compounds in pharmacokinetic development
• Biochemical reaction optimization—including protein refolding, ligand binding, and antigen-antibody equilibration—where kinetic reproducibility depends on thermal and mechanical stability
• Environmental sample processing, such as BOD incubation or nutrient extraction from soil/water matrices

FAQ

What is the maximum recommended load capacity for continuous operation?
The SYWF-60 is rated for sustained operation at full mechanical and thermal load—up to 15 kg distributed evenly across the tray—as verified under ISO 8573-1 clean compressed air–free conditions. Exceeding this mass may compromise speed stability and temperature uniformity.
Does the unit support programming multiple sequential setpoints (e.g., ramp-hold cycles)?
No. The SYWF-60 implements single-setpoint control only. Complex thermal profiles require external programmable timers or integration with a PLC-based environmental controller.
Can the water bath be filled with liquids other than deionized water?
Yes—glycerol/water mixtures or silicone oil may be used for extended high-temperature operation (>80 °C), provided viscosity remains below 50 cSt and compatibility with 304 stainless steel is confirmed. Ethanol or acetone are strictly prohibited due to material degradation and fire hazard.
Is there a factory calibration certificate included with shipment?
A basic出厂 calibration report (temperature and speed verification at 37 °C/100 rpm) is provided. NIST-traceable certification requires separate purchase and on-site verification by an accredited metrology provider.
What maintenance intervals are recommended for optimal performance?
Drain and refill the bath weekly if used daily; inspect drain valve seal and heating element insulation quarterly; verify temperature sensor drift annually using a calibrated reference thermometer per ASTM E74.
