Overview
The GM-0604 Single-Row 6-Position Digital Display Constant-Temperature Water Bath is a precision-engineered thermal platform designed for consistent, uniform heat transfer to multiple sample containers simultaneously. Operating on the principle of convection-based liquid-phase temperature stabilization, it maintains stable bath temperatures across its full working range (room temperature +5 °C to 100 °C) via a calibrated digital PID control system. Unlike dry-block or air-circulating ovens, water baths provide superior thermal homogeneity and gentle, non-evaporative heating—critical for temperature-sensitive applications such as enzyme incubation, serological testing, reagent equilibration, and solvent-based sample preparation. Its single-row 6-position configuration optimizes benchtop footprint while enabling parallel processing of up to six standard-sized beakers, test tubes, or flasks (up to 500 mL capacity each), making it especially suitable for QC laboratories, teaching labs, and R&D environments where throughput and repeatability are essential.
Key Features
- Stainless steel inner chamber and lid—resistant to corrosion from water, mild acids, and saline solutions; fully cleanable and compatible with routine decontamination protocols
- Digital PID temperature controller with real-time display, adjustable setpoint resolution of 0.1 °C, and thermal stability of ±0.5 °C at steady state
- 1500 W high-efficiency immersed heating element ensuring rapid heat-up time (<30 min to reach 95 °C from ambient) and minimal temperature overshoot
- Electrostatically coated carbon steel outer housing—mechanically robust, scratch-resistant, and compliant with ISO 9001 manufacturing practices
- Over-temperature protection circuit with independent mechanical cutoff (non-resettable fuse) meeting IEC 61010-1 Class II safety requirements
- Low-profile design (90 mm bath depth) optimized for compatibility with common labware; no external circulation pump required
Sample Compatibility & Compliance
The GM-0604 accommodates standard cylindrical vessels including glass beakers (50–500 mL), borosilicate test tubes (12–25 mm OD), and polypropylene centrifuge tubes. Its uniform thermal field—validated per ASTM E2208 “Standard Practice for Calibration of Liquid-in-Glass Thermometers”—ensures <±0.3 °C inter-well variation across all six positions when operated at 37 °C and 60 °C. While not certified for GLP/GMP-regulated workflows out-of-the-box, the unit supports audit-ready operation when paired with external calibration logs and documented maintenance records. It conforms to general-purpose laboratory equipment requirements under ISO/IEC 17025 Clause 6.4.3 (equipment verification) and may be integrated into validated processes with user-defined IQ/OQ protocols.
Software & Data Management
This analog-digital hybrid instrument operates without embedded firmware or network connectivity. Temperature data is displayed locally on a 3-digit LED screen; no USB, RS-232, or Ethernet interface is provided. For laboratories requiring electronic recordkeeping, optional external data loggers (e.g., Omega OM-DAQPRO-5300 series) can be connected via PT100 probe input to capture time-stamped bath temperature profiles. All calibration and performance verification activities—including daily drift checks and quarterly accuracy validation against NIST-traceable reference thermometers—are fully documentable per FDA 21 CFR Part 11 principles when conducted using controlled worksheets and versioned SOPs.
Applications
- Biological sample incubation: bacterial culture media pre-warming, serum inactivation, DNA denaturation/annealing steps
- Chemical synthesis support: solvent reflux pre-heating, hydrolysis reaction control, viscosity standardization
- Pharmaceutical QA/QC: dissolution medium conditioning (USP ), tablet coating uniformity testing
- Environmental testing: BOD incubation, nutrient solution equilibration for algal growth assays
- Educational use: undergraduate kinetics experiments, calorimetry demonstrations, and thermal property labs
FAQ
What is the maximum operating temperature and how is thermal uniformity verified?
The bath achieves a maximum setpoint of 100 °C with a guaranteed stability of ±0.5 °C at any selected temperature between RT+5 °C and 95 °C. Uniformity is confirmed by multi-point probe mapping per ASTM E2208.
Is the unit suitable for use with organic solvents?
No. The GM-0604 is rated exclusively for aqueous media. Use with flammable or volatile organics poses fire and vapor inhalation hazards and voids the safety certification.
Can the temperature controller be recalibrated by the end user?
Yes—via front-panel offset adjustment (±5.0 °C range) using a NIST-traceable reference thermometer and manufacturer-provided procedure (Document No. GM-0604-TC-Rev3).
Does the unit include a drain valve?
No. Drainage requires manual tilting or siphoning; an optional aftermarket drain kit (Part #DB-KIT-GM) is available separately.
What electrical supply is required?
Standard 220–240 VAC, 50/60 Hz, grounded single-phase supply with minimum 16 A circuit protection.
