INSTALLING THE DEVICE

Place the centrifuge onto a level , horizontal surface. Make sure that the ventilation slits are not blocked.
Insert the column connector of the adapter to power connector of the device ,and insert another connector of the adapter to mains power supply.
A safety distance of 30 cm should be observed around the centrifuge during operation.
No objects which could cause additional damage in the event of a centrifuge crash should be positioned in this space.
Power on the main switch. The centrifuge is ready to operate when the display becomes visible. Place the rotor onto the rotor axle and tighten using the rotor nut.
Before starting up the centrifuge for the first time, make sure the rotor nut is securely fastened.

TECHNICAL DATA

SAFETY PRECAUTIONS

The rotor and the rotor lid must always be securely fastened. If the centrifuge makes unusual noises when started , the rotor or rotor lid is not fastened correctly.
Switch the device off immediately by pressing “START/STOP” key.

Do not use damaged rotors!

Do not move the centrifuge during the run!

PLACE THE TUBES

A liquid density of 1.2 g/ml must not be exceeded at the max. speed.
Damaged tubes can not be centrifuged. This is because broken tubes can, in addition to sample loss, result in further damage to the centrifuge.
Close the test tube lids before centrifuging. Open lids can be ripped off during centrifugation and damage the centrifuge. Must load the test tubes symmetrically.

MAINTAIN OF ROTOR

Even slight scratches and tears of the rotor can lead to serious internal material damage.
Avoid damage caused by aggressive chemicals, including among others: strong and weak alkali, strong acids.
In the event of contamination caused by aggressive agents, The rotor must be cleaned immediately using a neutral cleaning liquid.

OPERATION GUIDE

CONTROL ELEMENTS

• START/STOP for start or stop centrifugation
• SHORT-SPIN for reduced-time centrifugation
• OPEN to open the lid
•    for setting the time and speed

ROTOR INSERTION AND REMOVAL

Fit the rotor onto the motor shaft, followed by the rotor nut. Tighten the rotor nut by turning clockwise. To release the rotor, turn the rotor nut counterclockwise. Before each start, check that the rotor is firmly tightened!

LOADING THE ROTOR

Rotor must always be loaded symmetrically. Minimize differences in weight between the filled sample tubes-taring with a scale is recommended. This will reduce wear on the drive and cut running noise.

CENTRIFUGATION WITH A PRESET TIME

Turn on the mains switch, pressing “OPEN” to open the lid, load the rotor symmetrically.
Fasten the rotor lid and close the centrifuge lid.
Pressing Time’s    change the run time, the time can be pre-selected between 20 seconds and 99 minutes, and pressing speed’s    to change the run speed， the max. speed is 5000 rpm.
Pressing the first “START/STOP” to start the run. Pressing the second “START/STOP” to end the run prematurely. The remaining run time appears in the display.
After the run, the lid lock of centrifuge opens automatically.
The time setting and the rotational speed may be changed during the run. The remaining run time appears in the display.

SHORT-SPIN CENTRIFUGATION

Turn on the mains switch, pressing “OPEN” to open the lid, load the rotor symmetrically. Fasten the rotor lid and close the centrifuge lid.
Pressing “SHORT-SPIN”. Short-spin centrifugation is possible for as long as this key is held down. The maximum rpm is 5000.

SWITCHING TO THE RCF DISPLAY

Pressing speed’s    simultaneously the display switches from rpm to rcf. Also
pressing speed’s    simultaneously again, the display switches from rcf to rpm.
You can calculate with the following formula:

rcf = 1118 * 10-5 * n2 * rmax
n: rotational speed in 1/min
rmax = 6 cm, max. centrifuging radius in cm

OPEN THE CENTRIFUGE IN THE EVENT OF A POWER FAILURE

Disconnect the centrifuge from the mains supply. Wait until the rotor has come to a standstill, Then left up the device, remove the lock pole to right , the lid lock will be opened.

MAINTENANCE AND CLEANING

The rotor and the outside of centrifuge should be cleaned regularly with a moist cloth. Disconnect the centrifuge from the mains supply, remove the rotor and clean it separately. Only neutral agents may be used for cleaning.

Please check the rotor and especially the rotor bores regularly for deposits or damage, then reinsert the rotor and tighten the rotor nut.
