CZGY ZQ-S6 Steam-Generating Water Bath

Overview

The CZGY ZQ-S6 Steam-Generating Water Bath is an engineered constant-temperature laboratory device designed for simultaneous water bath incubation and controlled steam generation. Unlike conventional water baths that solely maintain liquid-phase thermal stability, the ZQ-S6 integrates a high-power (2000 W) resistive heating system with a sealed, corrosion-resistant 304 stainless steel chamber to sustain stable water temperatures from ambient +5°C up to 100°C — enabling continuous boiling and steam production under user-defined operational conditions. Its thermal regulation relies on direct water conduction, ensuring uniform heat distribution across all six sample positions. The unit is not intended for precise steam temperature control; rather, steam output is a functional byproduct of sustained water boiling at atmospheric pressure. This dual-mode operation supports applications requiring both gentle aqueous thermal treatment and localized steam exposure — such as sterilization pre-treatment, enzymatic reaction initiation, or humidity-controlled sample conditioning.

Key Features

• Robust 304 stainless steel construction for both outer housing and inner bath tank, delivering long-term resistance to oxidation, chemical splashes, and repeated thermal cycling
• Dual-row, six-well configuration optimized for parallel processing of standard laboratory glassware (e.g., test tubes, flasks, beakers) with consistent thermal profiles across all positions
• Digital microprocessor-based temperature controller with LED display, offering intuitive setpoint entry and real-time monitoring with ±1°C accuracy over the full operating range (ambient +5°C to 100°C)
• Integrated automatic water replenishment system with float-sensor feedback loop, maintaining optimal fill level during extended operation
• Safety-critical low-water cutoff circuitry that deactivates heating elements immediately upon detection of insufficient water volume — preventing dry-run damage and fire hazard
• High-efficiency 2000 W heating element enabling rapid thermal equilibration and reliable maintenance of saturated steam conditions at atmospheric pressure

Sample Compatibility & Compliance

The ZQ-S6 accommodates a wide range of standard laboratory vessels including borosilicate glass test tubes (10–25 mm diameter), Erlenmeyer flasks (50–500 mL), and graduated cylinders. Its open-bath design allows unrestricted access for manual sample insertion, retrieval, and in-process observation. While not certified to ISO/IEC 17025 or ASTM E2879 for metrological traceability, the unit conforms to general electrical safety standards applicable to Class I laboratory equipment (IEC 61010-1). Its stainless steel materials meet FDA-recommended criteria for non-reactive surfaces in non-GMP research environments. For GLP-compliant workflows, users may configure external calibration logs and temperature verification protocols using NIST-traceable RTD probes.

Software & Data Management

The ZQ-S6 operates via embedded firmware without external software dependency. All control logic resides within its onboard microcontroller, eliminating compatibility constraints and cybersecurity exposure associated with networked instruments. Temperature setpoints, runtime status, and fault indicators are displayed locally on a high-contrast LED interface. Although it lacks USB or Ethernet connectivity, the unit supports manual data recording through periodic logging of setpoint, actual bath temperature, and operational duration — suitable for audit-ready lab notebooks in academic and industrial R&D settings. Optional external dataloggers (e.g., HOBO UX100 series) can be deployed for time-stamped thermal profiling in validation studies.

Applications

• Precise temperature maintenance for enzyme assays, bacterial culture activation, and DNA denaturation/annealing steps where water-phase thermal transfer is preferred over air convection
• Steam-assisted sterilization of reusable tools and glassware prior to aseptic procedures in microbiology and cell culture labs
• Controlled humidity preconditioning of hygroscopic samples (e.g., polymers, pharmaceutical excipients) before mechanical or thermal analysis
• Supporting distillation setups by providing stable boiling water sources for steam-jacketed condensers or vapor-phase extraction manifolds
• Teaching laboratories requiring durable, intuitive instrumentation for thermodynamics and heat transfer demonstrations

FAQ

Can the ZQ-S6 regulate steam temperature independently?
No. Steam temperature is inherently tied to ambient pressure and cannot be decoupled from the boiling point of water. The unit maintains water temperature up to 100°C; steam generated is therefore saturated vapor at ~100°C and atmospheric pressure.
Is the bath volume adjustable?
The internal chamber dimensions are fixed at 465 × 310 × 120 mm. Effective usable volume depends on vessel height and water fill level, but maximum capacity approximates 18 L when filled to operational height.
Does the unit support remote monitoring or alarm outputs?
It does not feature analog voltage outputs, relay contacts, or network interfaces. All status feedback is local and visual via the front-panel display and indicator LEDs.
What maintenance is required for long-term reliability?
Routine descaling with diluted acetic acid solution is recommended every 3–6 months depending on local water hardness. Inspection of the water-level sensor and gasket integrity should accompany each quarterly service cycle.
Can the ZQ-S6 be used with corrosive or organic solvents?
No. It is rated exclusively for aqueous use. Introduction of organic solvents, strong acids, or alkalis will compromise material integrity and void warranty coverage.
