Precautions In order to ensure safe operation of the KR4i, the following general safety regulations must be followed: • The centrifuge should be operated by trained personnel only. The centrifuge is to be used for its intended purpose only. “Proper use” on page vi. Do not move the centrifuge while it is running. Do not use rotors which show any signs of corrosion and/or cracks. Do not touch the electronic components of the rotor and do not make any changes to the electronic or mechanical components. Use only with rotors which have been expertly installed. Use only with rotors which have...

Rotor installation: make sure the rotor is locked properly into place before operating the centrifuge. Especially when working with corrosive samples (salt solutions, acids, bases), the accessory parts and vessel have to be cleaned carefully. Always balance the samples. Centrifuging hazardous substances: • Do not centrifuge explosive or flammable materials or substances which could react violently with one another. The centrifuge is neither inert nor protected against explosion. Never use the centrifuge in an explosion-prone environment. Do not centrifuge toxic or radioactive materials or...

KR4i Large Capacity Refrigerated Centrifuge - 11

product Description The Jouan KR4i centrifuge is designed to separate substances of different density by centrifugal force. Different rotors can be fitted to the drive in order to match the sample containers and the required performance. The maximum speed (and, by consequence, the resultant centrifugal force) is a function of the rotor in use. A control system permits the speed, acceleration and braking rates, run time and temperature to be monitored and controlled. The refrigeration is assured by a refrigerant group charged with a CFC-free fluid. The refrigerant fluid circulates around the...

Chapter 1 Presentation of product Note To calculate actual results, press the keys on a pocket calculator in the order shown. Primary calculations Key sequence (not valid for CASIO, HP) To determine actual ‘g’ achieved at a different speed: N2 2 RCF2 = RCF1 ⎛ -------⎞ ⎝ N1⎠ To determine actual speed required to achieve a different ‘g’ at the same radius: N2 = N1 To determine actual speed required to achieve the same ‘g’ at a different radius: N2 = N1 Drive System The rotor is driven by a three phase asynchronous motor. The rotor is situated in the centre of an armour plated centrifugation...
