Overview
The Shanghai LabTech GM-0603 is a precision-engineered single-row four-well digital electric constant-temperature water bath designed for stable thermal conditioning of samples in routine laboratory workflows. Operating on the principle of convective heat transfer through a thermostatically controlled water medium, it delivers uniform and reproducible temperature environments across all four independent wells—each accommodating standard laboratory glassware such as test tubes, beakers, and flasks up to 500 mL capacity. Engineered for continuous operation under moderate thermal loads, the unit maintains setpoint stability within ±0.3 °C over extended periods, supporting applications requiring precise thermal input without active agitation or circulation. Its compact footprint (650 mm width) and low-profile design (90 mm height) optimize benchtop space utilization while ensuring compatibility with fume hoods and adjacent instrumentation.
Key Features
- Four parallel stainless-steel wells (each 170 mm deep, spaced linearly in a single row) fabricated from high-grade 304 stainless steel for corrosion resistance and long-term integrity in aqueous environments
- Digital PID temperature controller with LED display, offering adjustable setpoints from ambient +5 °C to 100 °C in 0.1 °C increments and real-time feedback via integrated Pt100 sensor
- 1000 W heating system with over-temperature cut-off protection and automatic power modulation to minimize thermal overshoot and drift
- Electrostatically coated carbon steel outer housing with smooth, non-porous finish for ease of cleaning and resistance to chemical splashes
- Removable stainless-steel lid with recessed well covers to reduce evaporation and improve thermal efficiency during overnight or unattended operation
- Compliance-ready design: meets IEC 61010-1 safety requirements for laboratory electrical equipment; compatible with GLP documentation protocols when paired with external calibration logs
Sample Compatibility & Compliance
The GM-0603 accommodates common cylindrical sample containers—including 12–18 mm test tubes, 50–250 mL Erlenmeyer flasks, and 100–500 mL beakers—without interference between adjacent wells. Each well features a standardized 170 mm internal depth and nominal 85 mm diameter, allowing full immersion of most volumetric glassware. The unit is routinely deployed in settings governed by ISO/IEC 17025-accredited quality systems, where traceable temperature verification (e.g., using NIST-traceable thermometers) and periodic performance qualification (PQ) are performed per internal SOPs. While not intrinsically compliant with FDA 21 CFR Part 11, its digital controller supports manual audit trails when used in conjunction with laboratory information management systems (LIMS) that enforce electronic signature and change-control policies.
Software & Data Management
This model operates as a standalone analog-digital hybrid instrument with no embedded firmware-based data logging or USB/Ethernet connectivity. Temperature setpoints and real-time readings are displayed locally only; however, the unit integrates seamlessly into validated workflows through external validation tools. Users may connect third-party calibrated thermistors or data loggers (e.g., Omega OM-DAQPRO-5300 series) to the bath’s external probe port (if equipped) or immerse reference sensors directly in adjacent wells for concurrent monitoring. All calibration records—including initial factory certification, annual verification reports, and deviation logs—must be maintained manually per ISO/IEC 17025 Clause 6.4.2 and USP Analytical Instrument Qualification guidelines.
Applications
- Enzyme kinetics assays requiring incubation at 37 °C or 60 °C under static thermal conditions
- Sample thawing and reconstitution of lyophilized reagents in clinical diagnostics laboratories
- Controlled evaporation of organic solvents during preparative chemistry workflows
- Standardization of viscosity measurements using capillary viscometers immersed in thermostated baths
- Pre-heating of culture media prior to sterile filtration in microbiology QC labs
- Accelerated stability testing of pharmaceutical formulations per ICH Q1A(R2) guidelines (when operated within specified temperature tolerances)
FAQ
What is the maximum operating temperature of the GM-0603?
The unit is rated for continuous operation up to 100 °C, with thermal cutoff activation at 105 °C.
Can the four wells operate at different temperatures simultaneously?
No—the GM-0603 features a single shared water reservoir and unified heating/temperature control system; all wells maintain identical setpoint temperatures.
Is distilled water required for operation?
Deionized or distilled water is strongly recommended to prevent mineral scale buildup on the heater element and stainless-steel surfaces, especially during prolonged use above 60 °C.
Does this model support external temperature probes for independent verification?
Yes—users may insert calibrated reference probes (e.g., PT100 or thermistor-based) directly into any well for parallel validation against the built-in sensor output.
What maintenance procedures are recommended for long-term reliability?
Monthly descaling with 5% citric acid solution, quarterly inspection of heater insulation resistance (>1 MΩ), and annual recalibration of the digital controller using a traceable reference thermometer.
