Silicon oil 50-250, transparent. 150cSt @ 50°C/122°F; 6cSt @
150°C/302°F. F.P. 315°C/599°F. Lifetime at 200°C/392°F is 1jr, at

The oil used has a limited lifetime.
The type brand and operating temperature mainly
determines lifetime. Spilling of sample may also reduce
lifetime and in some cases can start chemical reactions.
Silicon oil has the tendency to form gel, for this reason
silicon oil has to be replaced as soon as visible changes
like string forming are noticed. Within a few hours silicon
oil can transform itself into solid gel, which is very
difficult to remove. When not totally cleaned, very small
pieces of left over gel will catalyse new oil to form gel!
Do not use distilled water. This will cause corrosion
and wear of stirrer bearings.
Only use water as a bath fluid below 80°C/175°F.
Working for a longer period with water at
temperatures above 80°C will damage the stirrer
bearings.
When working at temperatures below 10°C / 50°F
ethylene-glycol should be added to the water. For
example, in the volume proportion of 50 / 50%.
