SECTION 1
INTRODUCTION
1.1 USE AND FUNCTION
NF 048 Bench Top Centrifuge is especially designed for the separation of blood samples, urine
particles sedimentation and for carrying out the other routine applications in the microbiology
laboratories.
NF 048 is a compact centrifuge that can be used both as microliter and hematocrit centrifuge.
With its microliter rotor accepting small capacity tubes up to 2 ml, NF 048 is ideal for hospital and
research laboratories and for applications such as pelleting of DNA and protein, DNA amplification,
enzyme tests, centrifugation of cells, yeast and microorganisms at high speed.
When NF 048 is operated with it is hematocrit rotor, it can be used for determining the hematocrit
volume by means of the centrifugation of blood samples in capillary tubes.
The body, lid and chamber of NF 048 is made of epoxy-polyester painted steel which means that
the centrifuge is resistant to external and internal effects.
By means of the programmable microprocessor control system speed (RPM or RCF) and time
could be programmed and the ‘pulse’ function provides the operator to run the programs of short
duration.
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. There is also an observation hole at the top of the instrument to
check the speed of the centrifuge by a tachometer.
NF 048 Bench Top 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.

The working bench should be durable to the device weight and vibration isolated.
Ensure that the rotor is placed correctly prior to usage.
According to the standard IEC 61010-2-020, anyone and any hazardous materials should not
be in the 300 mm safety zone while centrifuge is running.
Do not move the device while it is running.
Do not open the lid while rotor is spinning.
Apply the manual lid opening procedure in the case of power cut or in the case of any error.
Use only the the spare parts, rotors and accessories which are supplied by NUVE.
Load the rotor according to the explanations in the user’s manual.
Start the device after ensuring the rotor is loaded correctly.
Do not use the centrifuge in areas which are in explosive danger.
Do not centrifuge the explosive, flammable, radioactive, corrosive materials and the materials
which may react with each other.

covers, if hazardous, toxic and pathogenic microorganisms are centrifuged.

7
Do not use corrosive materials which may be harmful for the device integrity, rotor and
accessories.
Do not use rotors and accessories with corrosion and mechanical damages.
Mains supply should be appropriate to power of the device and grounded.
Use tubes whose sizes are suitable to the rotor and accessories.

force.
Use glass tubes to balance, if glass tubes are used. Use plastics tubes to balance, if plastics
tubes are used.
Do not start the device unless tubes are in balance.
