Remaining risk: Improper use can cause damages, contamination, and injuries
with fatal consequences.

Please pay particular attention to the following aspects:

• Location: well-ventilated environment, set-up on a level and rigid surface with adequate

load-bearing capacity.

• 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 inflammable substances.

• Do not centrifuge toxic or radioactive materials or any pathogenic micro-organisms

without suitable safety precautions.

When centrifuging microbiological samples from the Risk Group II (according to the
Bio-safety Manual" of the World Health Organization (WHO)), aerosol-tight biological
seals have to be used.

For materials in a higher risk group, extra safety measures have to be taken.

• If toxins or pathogenic substances have gotten into the centrifuge or its parts,

appropriate disinfection measures have to be taken (see “Disinfection” on page 5-4).

• Highly corrosive substances which can cause material damage and impair the

mechanical stability of the rotor, should only be centrifuged in corresponding protective
tubes.

WARNING

If a hazardous situation occurs, turn off the power supply to the centrifuge and leave the
area immediately.

Characteristics of the Heraeus Multifuge 4KR

The Heraeus Multifuge 4KR is a large volume, refrigerated universal centrifuge.

The Heraeus Multifuge 4KR is designed for large volume, high throughput laboratory needs. The
micro test plates and tubes can be centrifuged with the unique double rectangular bucket.

The Heraeus Multifuge 4KR is optimized for the automatic laboratory processes in clinical central labs.

The Diagnostik™ rotor allows the centrifuge commercial sample racks directly.

The Heraeus Multifuge 4KR is also a compact centrifuge for the separation of blood components. A
special wind shield rotor allows to process up to eight quintuple blood bag systems.

The Heraeus Multifuge 4KR is equipped with various safety features:

• The housing and rotor chamber consist of steel plate, the interior of armor steel, while the front

panel is made of high-impact resistant plastic.

• The door is equipped with a view port and a lock.

• The door of the centrifuge can only be opened while the centrifuge is switched on and the rotor

has come to a complete stop. The centrifuge cannot be started until the door has been closed
properly.

• The integrated rotor detection systems ensures that no inadmissible speed settings can be

pre-selected.

• Electronic imbalance detection, SMARTspin.

• Door emergency release: For emergencies only, e.g. during power failures (see “Mechanical

Emergency Door Release” on page 6-2).

Entering Parameters

Explanation of RCF Value

The relative centrifugal force (RCF) is given as a multiple of the force of gravity g. It is a unitless
numerical value which is used to compare the separation or sedimentation capacity of various
devices, since it is independent of the type of device. Only the centrifuging radius and the speed
come into play in it:

r = centrifuging radius in cm

n = rotational speed in rpm

The maximum RCF value is related to the maximum radius of the tube opening.

Remember that this value is reduced depending on the tubes and adapters used.

This can be accounted for in the calculation above if required.

K-Factor

The k-factor is an information on the sedimentation capacity of a rotor. You can calculate the
required sedimentation time of each rotor with this formula:

t = sedimentation time in hours

K = clearing factor of the rotor (K-factor)

S

= Sedimentation factor for sample particles in water at 20 °C in Svedbergs

20,w

The k-factors given in this manual refer to:

r

= bucket bottom, (bottom of cavity of fixed angled rotors)

max

= bucket upper edge, (upper edge of cavity of fixed angled rotors)

r

min

Tubes which have various radii due to adapter or micro plate carriers the k-factor can be calculated
by using this formula:

Mechanical Emergency Door Release

Mechanical Emergency Door Release

During a power failure, you will not be able to open the centrifuge door with the regular electric lid
release. A mechanical override is provided to allow sample recovery in the case of an emergency.
However, this should be used only in emergencies and after the rotor has come to a complete stop.

WARNING The rotor can still be spinning at high speed. If touched, it can cause serious
injuries.

Always wait a few minutes until the rotor has come to a stop without braking. The brake does not work
when there is no current. The braking process lasts much longer than usual.

Proceed as follows:

1. Make sure the rotor has stopped (view port in the door).

WARNING Never use your hand or any tools to brake the rotor.

2. Pull out the power supply plug.

3. On both sides of the housing is a white plastic plug which you can pry out of the back plate with a
screwdriver or a knife.
Pull the release cords attached to it at the same time to trigger the mechanical door release. The
door will open and the samples can be removed.
