Shengyan SCQ-Y600A Ultrasonic Constant-Temperature Water Bath

Overview

The Shengyan SCQ-Y600A Ultrasonic Constant-Temperature Water Bath integrates precise thermal control with high-intensity ultrasonic energy delivery in a single compact platform engineered for reproducible laboratory processes. It operates on the principle of piezoelectric transduction—converting electrical energy into mechanical vibrations at frequencies typically in the 40 kHz range—to generate cavitation within the liquid medium. Simultaneously, a PID-controlled 304 stainless steel immersion heater maintains temperature stability across the full operating range (ambient to 100 °C) with ±0.5 °C accuracy. The unit features an internal recirculation system that ensures uniform thermal distribution without external plumbing, minimizing thermal gradients and enhancing experimental repeatability. Designed for rigorous benchtop use in chemistry, pharmaceutical, and materials science laboratories, the SCQ-Y600A supports time-sensitive, temperature-dependent sonochemical reactions—including hydrolysis, nanoparticle synthesis, enzymatic activation, and solvent-assisted extraction—where synchronized thermal and acoustic input is critical.

Key Features

• 30-L capacity 304 stainless steel bath tank with corrosion-resistant finish and integrated drain valve for rapid fluid exchange
• 600 W ultrasonic generator with adjustable power output and digital timer (1–600 min), enabling precise control over sonication duration and intensity
• PID-based microprocessor controller with large backlit LCD display for independent real-time monitoring and setting of temperature and ultrasonic parameters
• 1500 W high-efficiency heating element embedded in the tank wall, delivering rapid heat-up and stable thermal equilibrium
• Sound-dampening lid and removable stainless steel mesh basket to reduce airborne noise and facilitate sample containment during sonication
• Internal recirculation pump ensuring homogeneous temperature distribution (±0.3 °C typical deviation across bath volume)
• Over-temperature and dry-run protection circuits compliant with IEC 61010-1 safety standards for laboratory equipment

Sample Compatibility & Compliance

The SCQ-Y600A accommodates standard laboratory glassware including Erlenmeyer flasks (up to 2 L), beakers, reaction vials, and ultrasonic cleaning baskets. Its open-bath configuration permits direct immersion of vessels or transducer-coupled probes (with optional accessories). The unit meets general-purpose safety requirements per IEC 61010-1 and conforms to electromagnetic compatibility (EMC) directives EN 61326-1. While not certified for GMP manufacturing environments, its temperature logging capability (via optional RS232/USB interface) supports GLP-aligned documentation when paired with validated third-party software. It is routinely employed in protocols referenced by ASTM D297, USP , and ISO 13320 for particle dispersion and dissolution studies requiring controlled thermal-sonic input.

Software & Data Management

The SCQ-Y600A includes a built-in data logging function capable of recording temperature setpoints, actual bath temperature, ultrasonic activation status, and elapsed time at user-defined intervals (1–60 s). Logged data can be exported via USB flash drive in CSV format for traceability and post-processing in Excel or statistical analysis platforms. Optional PC connectivity (RS232 or USB-to-serial adapter) enables remote parameter adjustment and real-time graphing using Shengyan’s LabControl Suite (v3.2+), which supports audit trail generation, user access levels, and export compliance with FDA 21 CFR Part 11 requirements when deployed with electronic signature modules and secure authentication.

Applications

• Sonochemical synthesis of metal oxide nanoparticles (e.g., TiO₂, ZnO) under controlled thermal conditions
• Accelerated extraction of bioactive compounds from botanical matrices (e.g., flavonoids, alkaloids) in compliance with pharmacopoeial monographs
• Cell lysis and protein solubilization for downstream Western blot or ELISA preparation
• Ultrasonic cleaning and degassing of optical components, microfluidic chips, and precision instrumentation parts
• Temperature-programmed polymer degradation studies involving poly(lactic acid) or chitosan hydrogels
• Calibration support for viscometers, densitometers, and refractometers requiring stable thermal baths

FAQ

What is the maximum recommended operating temperature for continuous use?
The SCQ-Y600A is rated for sustained operation up to 95 °C; prolonged use above this threshold may accelerate seal degradation and reduce transducer lifespan.
Can the ultrasonic frequency be adjusted?
No—the unit operates at a fixed nominal frequency of 40 kHz, optimized for broad-spectrum cavitation efficiency in aqueous and polar organic media.
Is external cooling required for extended sonication cycles?
Not inherently; however, for >30 min continuous ultrasonic operation above 60 °C, auxiliary air cooling of the transducer housing is recommended to maintain long-term reliability.
Does the unit support multi-step temperature ramping?
No—ramping functionality is not embedded in the base firmware; users must manually adjust setpoints or integrate with external programmable controllers via analog voltage input (0–5 V) if available.
What maintenance intervals are advised for optimal performance?
Inspect and clean the stainless steel tank and transducer surface every 200 operational hours; replace the ultrasonic transducer gasket annually or after 1,000 hr cumulative use.
