Overview
The Shanghai Youyi DK-S16 Single-Row Six-Position Electric Constant-Temperature Water Bath is a precision-engineered laboratory thermal management system designed for stable, uniform, and reproducible heating of samples in aqueous or water-miscible media. It operates on the principle of convective heat transfer via immersion heating—where U-shaped sheathed heating elements directly contact the bath fluid, minimizing thermal lag and ensuring rapid equilibration. Engineered for routine laboratory workflows requiring controlled thermal environments—from enzyme incubation and sample thawing to solvent evaporation and reagent pre-warming—the DK-S16 delivers consistent temperature distribution across all six independent wells within its 15-liter stainless-steel bath chamber. Its operational range spans from ambient +5 °C to 100 °C, making it suitable for applications that demand sub-boiling thermal control without pressurization.
Key Features
- Microprocessor-based PID temperature controller with 0.1 °C resolution and ±0.1 °C accuracy, displayed on a backlit LCD interface for real-time monitoring and adjustment.
- U-shaped tubular heating elements embedded in magnesium oxide insulation, fully immersed in the bath medium to maximize thermal efficiency and minimize energy loss.
- Robust 304 stainless-steel inner tank and lid, coupled with electrostatically sprayed carbon-steel outer housing, providing long-term resistance to corrosion, thermal oxidation, and mechanical wear.
- Over-temperature protection with simultaneous audible and visual alarm activation, automatically cutting power when preset safety thresholds are exceeded—ensuring sample integrity and operator safety.
- Single-row, six-well configuration with standardized well spacing (900 mm × 150 mm × 110 mm internal dimensions), optimized for compatibility with common laboratory glassware including 50–500 mL beakers, test tubes, and conical flasks.
- 1500 W high-power heating system enabling rapid recovery after sample loading and maintaining ±0.5 °C temperature uniformity across the entire bath volume under steady-state conditions.
Sample Compatibility & Compliance
The DK-S16 accommodates a wide range of sample containers—including borosilicate glass, polypropylene, and stainless-steel vessels—without risk of thermal degradation or leaching. Its open-bath design supports passive air exchange and avoids vapor condensation issues associated with sealed chambers. While not certified to ISO/IEC 17025 or ASTM E2251 for metrological traceability, the unit conforms to general electrical safety standards applicable to Class I laboratory equipment (IEC 61010-1). Its temperature stability profile meets typical requirements for GLP-compliant preparatory steps such as buffer equilibration, standard solution conditioning, and microbiological media warming—though final analytical validation remains the responsibility of the end user per institutional SOPs.
Software & Data Management
The DK-S16 operates as a standalone analog-digital hybrid instrument with no embedded data logging or network connectivity. All operational parameters—including setpoint, real-time temperature, and elapsed time—are displayed locally on the LCD screen. For laboratories requiring audit trails or electronic records, external USB or RS-232 data loggers (e.g., Omega OM-DAQPRO-5300 series) may be interfaced via optional analog output modules. The device supports manual timer operation up to 999 minutes, fulfilling basic workflow scheduling needs without software dependency. No firmware updates or cloud integration are provided; maintenance is limited to periodic calibration verification using NIST-traceable reference thermometers.
Applications
- Pre-warming of culture media, enzymatic reagents, and diagnostic kits prior to use in molecular biology and clinical microbiology labs.
- Controlled evaporation of organic solvents during sample concentration in environmental and pharmaceutical QC testing.
- Thermal equilibration of calibration standards for viscometers, spectrophotometers, and pH meters.
- Accelerated stability studies involving temperature-dependent hydrolysis or oxidation kinetics in chemical R&D.
- Supporting ASTM D92 (Cleveland Open Cup), ISO 2592, and USP auxiliary heating protocols where non-contact, water-mediated thermal transfer is specified.
- Graduate teaching laboratories for thermodynamics demonstrations, reaction rate investigations, and calorimetric baseline establishment.
FAQ
What is the maximum operating temperature of the DK-S16?
The DK-S16 is rated for continuous operation from ambient +5 °C up to 100 °C, with optimal long-term stability maintained below 95 °C.
Does the unit include a built-in timer with auto-shutdown?
Yes—it features a programmable mechanical/electronic timer adjustable from 1 to 999 minutes, with automatic power cutoff upon completion.
Can the DK-S16 be used with corrosive solutions like acid baths?
No. The stainless-steel tank is resistant to water and mild aqueous buffers but not compatible with strong acids, halogenated solvents, or alkalis above pH 10; alternative PTFE-lined or quartz-jacketed baths are recommended for such applications.
Is calibration documentation provided with the instrument?
Factory calibration certificates are not included by default; however, the unit includes a dedicated calibration port for third-party verification using a calibrated PT100 probe.
What safety certifications does the DK-S16 hold?
It complies with GB 4793.1–2007 (Chinese national standard equivalent to IEC 61010-1) for electrical safety in laboratory equipment; CE marking is not affixed unless ordered with EU-specific compliance configuration.
