1.1 USE AND FUNCTION
The NF 1200 / NF 1200 R centrifuges are designed to separate liquids of different densities by
applying centrifugal force. Different types of rotors, which are swing-out and angle rotors, can be
fitted to the centrifuges.
The microprocessor control system of the centrifuges enables the user to observe and to control
the speed (RPM or RCF), the acceleration and braking rates, run time, program number and
temperature of the bowl for NF 1200 R. The microprocessor control system also displays the RPM
or RCF value during the run.
The ventilation system of the NF 1200 limits temperature in the bowl between the ambiant
tempe 3 °C and ambiant tempe 12 °C depending on the rotor type. The NF 1200 R
is equipped with a cooling system which provides to operate between -
9 °C and + 40 ° C.
It ensures safe processes by means of the locking system which does not allow the centrifuge to
operate if the lid is open and which does not allow the rotor to spin if the lid is not closed.
The lid locking system which does not allow the centrifuge to operate if the lid is open, which also
does not allow the lid to be opened while the rotor is spinning and the possibility to open the lid by
pushing only one key when the program ends, provide safe and easy working conditions. There
are audible and visible alarms to inform the operator when the lid is open, when the program ends
and when any error conditions occur. In case of a power failure, the lid could be opened manually
by using a manual lid opening tool
The NF series centrifuges are manufactured according to the following standards,
EN 61010-1, EN 61010-2-020, EN 61000-6-3, EN 50419.
This device is in compliance with WEEE Regulation.
