Overview
The YiHeng TS-030 Transparent Circulating Water Bath is an engineered constant-temperature bath designed for precise thermal stabilization of samples in analytical, quality control, and research laboratory environments. Utilizing a robust stainless-steel inner tank and transparent acrylic side panels, the unit enables real-time visual monitoring of sample immersion and fluid dynamics without compromising structural integrity or thermal performance. Its heating-only architecture—combined with PID-based microprocessor temperature control—ensures stable setpoint maintenance across the operational range (RT+5 °C to 70 °C) with a resolution of 0.1 °C. The integrated internal circulation pump promotes uniform temperature distribution throughout the 27-liter working volume, minimizing axial and radial thermal gradients critical for reproducible incubation, enzymatic assays, viscosity calibration, and material conditioning protocols.
Key Features
- Stainless-steel inner tank and lid—resistant to corrosion, compatible with aqueous and mild chemical solutions, and compliant with ISO 15190:2020 laboratory equipment surface hygiene requirements.
- Microprocessor-controlled digital display with timer function—supports user-defined hold durations and automatic shutdown to prevent overheating or extended unattended operation.
- Over-temperature audio-visual alarm system—triggers at user-configurable thresholds to safeguard samples and meet GLP-compliant environmental monitoring expectations.
- Three independent water bath compartments—each equipped with dedicated heating elements and temperature sensors—enabling simultaneous multi-condition experiments (e.g., comparative kinetic studies or reference-standard equilibration).
- Optional multi-segment programmable controller—supports up to 30 programmable steps per cycle, including ramp rates, dwell times, and power modulation; conforms to IEC 61000-4-30 for electromagnetic compatibility in shared lab infrastructure.
- Adjustable circulation pump speed—allows optimization of flow rate (0–3.5 L/min typical) to balance thermal homogeneity against shear-sensitive sample integrity.
Sample Compatibility & Compliance
The TS-030 accommodates standard laboratory glassware (e.g., beakers, flasks, cuvettes, and immersion probes) up to 200 mm in height and 120 mm in diameter per compartment. Its non-porous stainless-steel construction meets ASTM E1510-22 criteria for materials used in regulated thermal equipment. While not certified for sterile applications, the unit supports cleaning validation per USP Analytical Instrument Qualification when operated within documented SOPs. It is suitable for use in environments aligned with ISO/IEC 17025:2017 clause 6.4.7 (environmental conditions for equipment operation), provided ambient room temperature remains between 15–30 °C and relative humidity does not exceed 80% RH non-condensing.
Software & Data Management
The base configuration includes standalone front-panel operation with non-volatile memory for retaining last-used parameters after power loss. When equipped with the optional programmable controller, the unit supports RS-232 serial output (ASCII protocol) for integration into LabView, MATLAB, or custom SCADA systems. Data logging—time-stamped temperature readings at user-selectable intervals (1 s to 60 min)—can be exported to CSV for traceability. Audit trail functionality, including operator ID tagging and parameter change history, is available under FDA 21 CFR Part 11-compliant configurations when paired with validated third-party software platforms.
Applications
- Thermal pre-conditioning of polymer standards prior to DSC or TGA analysis
- Enzyme activity assays requiring strict temperature constancy (e.g., amylase, protease kinetics per ISO 2013)
- Calibration of liquid-in-glass thermometers and digital temperature probes against NIST-traceable references
- Stabilization of optical components during refractive index measurements
- Accelerated aging tests for pharmaceutical excipients per ICH Q1A(R2)
- Cell culture reagent warming under controlled, non-sterile benchtop conditions
FAQ
Is the TS-030 suitable for oil baths?
No—the unit is specifically engineered for aqueous media; its maximum operating temperature (70 °C) and stainless-steel grade (SUS304) are not rated for prolonged exposure to silicone or mineral oils above 60 °C.
Can external temperature probes be connected?
Yes—via optional PT100 input port on the programmable controller module, enabling dual-point verification and chamber-to-sample delta-T monitoring.
Does it support remote start/stop via network interface?
Not natively; Ethernet or Wi-Fi connectivity requires integration through an external industrial gateway configured for Modbus TCP communication.
What is the mean time between failures (MTBF) under continuous operation?
Based on accelerated life testing per IEC 62380, the estimated MTBF exceeds 25,000 hours for heater assemblies and 30,000 hours for the circulation pump under nominal load conditions.
Is CE marking applicable?
The TS-030 complies with EU Machinery Directive 2006/42/EC and Low Voltage Directive 2014/35/EU; CE documentation is available upon request for export compliance verification.
