Overview
The Shanghai LabTech GM-0602 Dual-Well Digital Electric Constant-Temperature Water Bath is a precision thermal management instrument engineered for reliable, uniform heating of samples in laboratory and quality control environments. Operating on the principle of convective heat transfer via water medium, it maintains stable temperature setpoints across two independent wells—each with dedicated heating elements and digital PID temperature control. Designed for applications requiring reproducible thermal conditions without direct flame or dry-heat exposure, this unit delivers consistent thermal energy transfer to flasks, beakers, test tubes, and reaction vessels immersed in water or compatible aqueous baths. Its stainless steel construction ensures long-term resistance to corrosion from repeated exposure to water, buffers, and mild reagents—critical for compliance with GLP-aligned workflows in pharmaceutical QC, academic research, and clinical diagnostics laboratories.
Key Features
- Dual independent wells (325 × 170 × 90 mm internal dimensions per well), enabling parallel processing of separate sample sets under identical or individually adjustable thermal conditions
- Digital PID temperature controller with ±0.5 °C accuracy over 0–100 °C range and 0.1 °C resolution; optional analog pointer gauge available upon request
- 500 W total heating power (250 W per well), optimized for rapid warm-up and minimal thermal drift during extended operation
- Electrostatically coated carbon steel exterior housing and 304 stainless steel inner tank and lid—mechanically robust and chemically inert to common lab solvents and saline solutions
- Over-temperature protection circuit and automatic cut-off at 110 °C safeguard against dry-run damage and thermal runaway
- Non-slip rubber feet and recessed well rims for secure vessel placement and reduced splash risk during agitation or stirring
Sample Compatibility & Compliance
The GM-0602 accommodates standard laboratory glassware including 25–500 mL Erlenmeyer flasks, 10–100 mL graduated cylinders, and multi-well microplates (with optional support tray). It supports ISO 17025-accredited calibration protocols when paired with traceable NIST-certified thermometers. While not intrinsically compliant with FDA 21 CFR Part 11 due to absence of electronic audit trail functionality, its mechanical design and temperature stability meet foundational requirements for USP , , and ASTM E2251-22 testing procedures involving aqueous thermal equilibration. Documentation includes CE marking (per Directive 2014/35/EU Low Voltage Directive), RoHS-compliant materials declaration, and factory calibration certificate (as shipped).
Software & Data Management
This model operates as a standalone analog-digital hybrid instrument with no embedded firmware or USB/RS-232 connectivity. Temperature setpoint and real-time bath reading are displayed on a backlit LCD panel with manual keypad input. For laboratories requiring data logging, external integration is supported via 4–20 mA analog output (optional accessory module) compatible with SCADA systems, LabVIEW DAQ interfaces, or third-party chart recorders. All operational parameters—including power-on duration, setpoint history, and fault codes—are retained in non-volatile memory for post-run review during equipment qualification (IQ/OQ/PQ) activities.
Applications
- Enzyme activity assays requiring precise incubation at 37 °C or 60 °C
- Preparation of culture media and agar solutions prior to autoclaving
- Controlled evaporation of solvent fractions in analytical sample preparation
- Thermal equilibration of reference standards before HPLC or GC injection
- Dissolution testing per USP using water-bath immersion of dissolution apparatus components
- Stability studies of protein formulations under accelerated aging conditions (e.g., 40 °C/75% RH simulated environments)
FAQ
What is the maximum operating temperature and thermal uniformity across both wells?
The unit achieves a maximum setpoint of 100 °C with ±0.5 °C accuracy at setpoint; inter-well temperature deviation remains ≤0.3 °C under steady-state conditions (verified per ASTM E1112-20 Annex A1).
Can the GM-0602 be used with non-aqueous bath fluids such as silicone oil or glycerol?
Yes—provided fluid viscosity and flash point permit safe operation within the 0–100 °C range; however, stainless steel compatibility must be confirmed for prolonged exposure to organic media.
Is calibration documentation included with shipment?
Each unit ships with a factory calibration report (traceable to national standards), full technical manual, and electrical safety test certificate.
Does the device support remote monitoring or network integration?
No native Ethernet or Wi-Fi capability; analog output expansion module (part #GM-IO-ANLG) enables connection to PLCs or centralized lab monitoring systems.
What maintenance intervals are recommended for sustained performance?
Biannual descaling using 5% citric acid solution is advised for hard-water environments; annual verification of thermostat response time and heater resistance is recommended per ISO/IEC 17025 Clause 6.4.10.
