The Thermostatic Water Bath (BIO-0675) is a precision laboratory heating instrument designed for consistent temperature control in research and analytical applications. This triple-chamber unit provides three independent 3.9L compartments, each with PID digital temperature control capable of maintaining temperatures from RT+5°C to 100°C with ±0.5°C precision. The system incorporates programmable timing functionality (0-9999 minutes or continuous operation) and uniform heat distribution throughout each chamber.
Each chamber maintains temperature uniformity within ±0.5°C, with 0.1°C resolution for precise thermal control. The compact external footprint (533×311×260mm) houses three separate working chambers (150×174×148mm each), making this unit suitable for multi-sample processing or simultaneous experiments requiring identical thermal conditions. The 900W heating system ensures rapid temperature equilibration while maintaining stable operating conditions.
How It Works
The thermostatic water bath operates through precisely controlled heat transfer in an aqueous medium. Water circulation within each chamber distributes thermal energy uniformly, creating a stable temperature environment for immersed samples. The PID (Proportional-Integral-Derivative) digital control system continuously monitors chamber temperature via integrated sensors and modulates heating element output to maintain setpoint temperature within ±0.5°C.
Each of the three independent chambers functions as a separate thermal zone, allowing simultaneous processing at identical or different temperatures. The heating system utilizes 900W total power distributed across chambers for rapid temperature equilibration. Temperature uniformity is maintained through convective circulation patterns within each chamber, ensuring consistent thermal conditions throughout the working volume.

Practical Tips
Verify temperature accuracy using a NIST-traceable thermometer at multiple points across the working range before critical experiments.
Why: Ensures measurement traceability and validates system performance for analytical applications.
Clean chambers weekly with mild detergent and rinse thoroughly to prevent mineral buildup and maintain heat transfer efficiency.
Why: Mineral deposits reduce heating efficiency and can affect temperature uniformity across the chamber.
Allow 15-20 minutes for temperature equilibration before introducing samples and avoid filling chambers beyond recommended levels.
Why: Proper equilibration ensures thermal stability while correct fill levels maintain circulation patterns necessary for temperature uniformity.
Monitor water levels during extended operation and never operate chambers without adequate water coverage of heating elements.
Why: Prevents damage to heating elements and potential fire hazard from dry heating conditions.
Record chamber temperature at the start and end of each experimental run for documentation and quality control purposes.
Why: Provides thermal history documentation required for analytical method validation and troubleshooting.
If temperature uniformity degrades, check for adequate water circulation and remove any obstructions blocking convective flow patterns.
Why: Proper circulation is essential for uniform heat distribution and maintaining specified temperature tolerance across the chamber volume.

Compliance
What is the temperature recovery time when adding room temperature samples?
Recovery time varies with sample volume and thermal mass, but the 900W heating system typically restores setpoint temperature within 10-15 minutes for standard sample loads. Consult product datasheet for specific recovery characteristics.
Can each chamber operate at different temperatures simultaneously?
Yes, each of the three chambers has independent PID temperature control, allowing different setpoints and timing parameters for simultaneous multi-condition experiments.
What is the maximum sample vessel size that fits in each chamber?
Each chamber accommodates vessels up to the internal dimensions of 150×174×148mm, allowing for standard laboratory glassware including beakers, flasks, and sample tubes.
How frequently should temperature calibration be performed?
Temperature calibration frequency depends on usage intensity and accuracy requirements, but quarterly calibration using NIST-traceable thermometers is typical for analytical applications.
What type of water should be used in the chambers?
Distilled or deionized water is recommended to prevent mineral buildup and corrosion of heating elements, extending equipment life and maintaining thermal transfer efficiency.
Can this unit operate continuously for extended periods?
Yes, the system supports continuous operation mode and is designed for extended use with proper water level maintenance and routine cleaning of chambers.
What safety features are included for over-temperature protection?
Consult product datasheet for specific safety features. Standard water baths typically include temperature limit controls and dry-heating protection systems.
