FN 400/500 Economical Dry Heat Sterilizers / Ovens

Shallow format for easy sample access

Offering a low level alternative to the other FN models, this series can be stacked. It is available in a choice of aluminum lining (excellent when temperatures are going to be varied) or stainless steel (P models, the choice for maximum temperature stability). N-Prime™ control system ensures rapid attainment of the target temperature.

The timer function lends itself to drying, so that the dried contents are back at a low temperature at a convenient time, and for sterilization, so that it is certain that the contents have been subjected to sterilization conditions for an adequate period. Out of range alarms alert the user in case of a power interruption.

Forced ventilation is optional. It is not required to achieve acceptable operation but is useful when the ovens are used for drying, since the removal of evaporated water vapour accelerates the drying process.
