Silicon oil 200-10, transparent. 10 mm²/s @ 25°C/77°F;10 mm²/s
@ 150°C/301°F. F.P. 211°C/411°F. Lifetime >2 years.
The oil used has a limited lifetime.
The type, brand and operating temperature mainly
determines lifetime. Spilling of sample may also reduce
lifetime, 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
are noticed like string forming. 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 catalyze new oil to form gel!
Do not use distilled water. This will cause serious
corrosion.
Only use water as a bath fluid below 80°C/176°F.
Working for a longer period with water at
temperatures above 80°C will damage the stirrer
bearings.
Using the bath for long periods at low temperatures
will cause condensation on the glass window
resulting in complete invisibility of material placed
inside the bath.
