The low viscosity keeps the fluid pumping freely at cryogenic-range temperatures where heavier oils thicken. Labs reach for C2 when a circulator must hold low setpoints with stable flow.\u003c\/p\u003e\n\u003cp\u003eSilicone chemistry stays chemically inert against common metals and carries very low electrical conductivity. Operators should avoid silicone tubing, which silicone fluids degrade. Prolonged sub-ambient runs in humid air can draw atmospheric moisture into the bath, so monitor for condensation.
