Silicon oil deterioration rate (viscosity change) varies with operation temperature. Please contact
silicon oil manufacturer for product details at time of purchase.
Water/oil bath levels
Maximum fluid bath level (water/silicon oil) when heated should be approximately 30 mm or less from
top of bath container when specimen flasks are submersed.
Exercise caution in the amount of silicon oil supplied to oil bath.
Do not use more than three (3) liters in the bath container.
Silicon oil has a broad thermal expansion capacity and may overflow from bath when heated,
if too much oil is added.
Max 3 liters
CAUTION!
