JULABO Thermal Bath Fluids

Product catalog summary
General Information
JULABO Thermal Bath Fluids are designed for use with JULABO units, offering chemical inertness and low electrical conductivity. They are stable for at least 12 months if stored properly. Regular inspection and replacement every 2-3 months are advised, especially near temperature limits. Silicone-based fluids should not be used with silicone hoses due to potential material incompatibility.
Types of Bath Fluids
  • Silicone-Based Fluids: High stability and minimal oxidation, suitable for a wide temperature range but require specific tubing materials.
  • Water-Glycol Based Fluids: Excellent thermal characteristics and anti-freeze protection, requiring regular checks of the water-glycol ratio.
Specific Bath Fluids
  • Thermal G: Water-glycol based, suitable for -30°C to +80°C.
  • Thermal M: Alcohol ethoxylate based, suitable for +70°C to +170°C.
  • Thermal HS: Silicone-based, suitable for +50°C to +250°C.
  • Thermal HY: Silicone-based, suitable for -80°C to +55°C.
  • Thermal H5: Silicone-based, suitable for -50°C to +105°C.
  • Thermal H10: Silicone-based, suitable for -40°C to +180°C.
  • Thermal H20S: Silicone-based, suitable for 0°C to +220°C.
  • Thermal HL30: Water-glycol based, suitable for -30°C to +90°C.
Recommendations
Selection of bath fluid should consider the working temperature range and compatibility with JULABO units. Regular monitoring and maintenance are crucial for performance and safety.

The Temperature Control Company Bath fluid Thermal G JULABO Thermal G is a bath fluid based on water-glycol and features excellent thermal properties. In addition, JULABO Thermal G supplies anti-freeze protection and thus it is most suitable for applications below the freezing point of water. Check the mixing ratio! When using Thermal G for long time periods, the mixing ratio of water to glycol must be checked regularly (50:50). In case of increased glycol content, the Thermal G may become flammable. Conversely, increased water content may cause the Thermal G to freeze at low temperatures. Please...
