Peter Huber Thermofluid M90.055.03 SilOil (5 Liters)

Peter Huber Thermofluid M90.055.03 SilOil (Order No. 6258) is a premium, low-viscosity silicone oil engineered for extreme low-temperature applications in laboratory and industrial thermoregulation. This high-quality heat transfer medium is specifically designed to provide optimal thermodynamic performance while maintaining high environmental safety standards. Characterized by its exceptional fluidity at sub-zero temperatures, M90.055.03 ensures rapid heat transfer and precise temperature control. It is ideally suited for use in Huber Unistats and other closed-loop systems where high-speed temperature changes and extreme cooling depths are required.

Key Features:

• Extreme Temperature Range: Operates from -90°C up to +55°C in open/closed systems, and can be extended up to +170°C in externally sealed systems (such as Huber Unistats).
• Low Viscosity: Features a very low viscosity of approximately 2 mm²/s at 25°C, ensuring high flow rates and efficient heat exchange even at the lowest temperatures.
• Superior Stability: Chemically inert, colorless, and odorless polydimethylsiloxane base provides excellent long-term thermal stability.
• Safety Profile: Non-toxic and not classified as a hazardous substance or dangerous good, simplifying handling and storage.
• System Compatibility: Optimized for use in closed-loop systems to prevent oxidation and moisture absorption, significantly extending the fluid's service life.
• Material Compatibility: Safe for use with most metals and plastics, though care should be taken with silicone-based seals or gaskets.

Huber M90.055.03 SilOil is the professional choice for pharmaceutical research, aerospace testing, and chemical engineering processes requiring cryogenic temperatures. By minimizing the internal resistance of the circulation pump through its low viscosity, it allows temperature control units to reach their maximum cooling speed and efficiency.

Frequently Asked Questions

1. Why is the temperature range different for open vs. closed systems?
In open systems, the maximum temperature is limited to +55°C to avoid significant evaporation and the potential for the fluid to reach its flashpoint. In closed, externally sealed systems (like Unistats), the fluid can safely reach +170°C as it is not in contact with ambient oxygen.

2. Can I mix M90.055.03 with other silicone oils?
Since this fluid is based on polydimethylsiloxane, it is generally miscible with other Huber SilOils. However, mixing fluids will alter the thermodynamic properties and the specific temperature range of the medium.

3. What is the shelf life of Huber SilOil?
When stored in its original, tightly sealed container in a cool, dry place, the fluid has an almost indefinite shelf life. Once in use, the life of the fluid depends on the operating temperatures and moisture exposure.

4. Is this fluid compatible with silicone tubing?
No. Like all silicone-based thermal fluids, M90.055.03 will cause silicone rubber and silicone-based gaskets to swell and eventually fail. Use PTFE, EPDM, or metal hoses instead.

5. Does this fluid require a special disposal process?
While it is non-toxic, used thermal fluid should be disposed of in accordance with local chemical waste regulations for "waste oils" or "silicone-containing liquids."
