Peter Huber Thermofluid M60.115.05 SilOil (10 Liters)

The Peter Huber Thermofluid M60.115.05 SilOil (Order No. 6166) is a high-performance silicone-based heat transfer fluid specifically formulated for use in Huber circulators, Unistats, and chillers. Supplied in a convenient 10-liter container, this medium-viscosity SilOil offers an excellent balance between low-temperature fluidity and high-temperature stability. Engineered to provide superior thermodynamic properties, M60.115.05 ensures efficient heat transfer and precise temperature control. It is an ideal choice for laboratories requiring a wide operating window for chemical synthesis, pharmaceutical research, and quality control testing within closed-loop systems.

Key Features:

• Versatile Working Range: Specifically designed for operation from -60°C up to +115°C in open systems, with the capability to reach up to +175°C in externally sealed (closed) systems.
• Optimized Viscosity: Features a viscosity of 5 mm²/s at 25°C, providing the necessary lubricity for internal pump components while maintaining excellent flow characteristics at sub-zero temperatures.
• High Thermal Stability: Based on polydimethylsiloxane, the fluid is chemically inert, non-corrosive, and resistant to oxidation when used in Huber closed-loop technology.
• Safety and Compliance: Non-toxic, odorless, and not classified as a hazardous substance, making it safer for laboratory personnel and easier to transport.
• Eco-Friendly: Features a high Global Warming Potential (GWP) advantage over synthetic alternatives and is CFC/HCFC-free.
• Efficiency: Optimized for high heat capacity and thermal conductivity to ensure rapid response times during temperature ramps.

Choosing the correct Huber Thermofluid is essential for the longevity of your equipment. M60.115.05 SilOil is meticulously tested to ensure compatibility with Huber’s internal gaskets, seals, and evaporators. By maintaining its properties over long periods, it reduces maintenance requirements and ensures consistent, reproducible results for sensitive thermal processes.

Frequently Asked Questions

1. Why is the maximum temperature limited in an open bath?
In an open bath system, the fluid is in contact with atmospheric oxygen. To prevent premature aging, oxidation, and the risk of reaching the fluid's flashpoint, the temperature is capped at +115°C. In a closed system like a Unistat, it can safely reach +175°C.

2. Is this fluid compatible with silicone tubing?
No. As a silicone-based oil, M60.115.05 will cause silicone-based hoses and gaskets to swell and lose structural integrity. We recommend using Huber's insulated metal hoses or PTFE/EPDM-based connections.

3. Can I mix M60.115.05 with other SilOils?
While chemically compatible with other polydimethylsiloxane fluids, mixing different Huber SilOils will change the viscosity and the effective temperature range of the mixture. It is best practice to use a single grade of fluid for consistent performance.

4. How should the fluid be stored?
Store the 10L container in a cool, dry place away from direct sunlight. Ensure the cap is tightly sealed to prevent the absorption of ambient moisture, which can lead to "popping" sounds or bubbling at high temperatures.

5. When should I replace my SilOil?
The fluid should be replaced if it becomes significantly discolored (darkened), develops a strong odor, or if you notice a decrease in the heating/cooling speed of your circulator.
