• Indoor use.

• Temperature: 5°C to + 40°C.

• Maximum relative humidity of 80% for temperatures up to 31°C
decreasing linearly to 50% relative humidity at 40°C.

• Installation category: II

• Pollution degree: 2

1. Switch the centrifuge on trough the main on the right side of the
unit.

2. When the centrifuge is switched on but stationary: LID led on at
the opening.

3. The mechanic unlocks and consequent opening of the lid is
obtained by pulling the lever on the right side of the machine
towards the centrifuge front.

Warning Before proceeding to installation operations, it is advisable to
disconnect the centrifuge from the mains, by moving the POWER
switch on “O” position. ▲

4. After opening the lid, remove any possible packaging around the
driving spindle. Unscrew the equipment-blocking nut from the
engine shaft.

5. Carefully clean the inside of the centrifugation chamber removing
any packing residues. Due to the air - whirling, solid particles
accidentally left in the centrifugation chamber would create an
excessive wear of the chamber itself and of the outer Equipment
rotating bottoms.

In the event of mains non-availability or power failure, the lid can be
opened by using the special tool supplied with the centrifuge.

This operation should always be effected with the centrifuge mains
plug disconnected.

1. Unscrew the nylon screw in the hole next to opening lever, and
here below identified by the corresponding label.

2. Insert horizontally the unlocking tool supplied with the centrifuge
in the hole (fig. a).

3. Lift the unlocking tool upwards and at the same time pull the lever
(fig. b).

4. At the end screw again the nylon screw.

Warning Should the emergency occur due to electricity failure, during
centrifugation (E4 message will be shown when the power is on again),
wait at least 5 minutes for the end of the Rotating Equipment rotation.
Upon opening, lift the lid by hand and observe the rotor (be careful in
this operation): if it is still rotating, close the lid and wait. ▲

Before any centrifugation run, the rotating equipment should be
thoroughly inspected for corrosion and cleanliness (see 6.3). The clip in
the center of the rotor and the drive spindle should also be clean and
undamaged.

Any failure to follow the above advice may have serious consequences
for the safety of the appliance.

If visible signals of corrosion or anomalies on the rotor or buckets are
present, contact the authorized personnel. Also the centrifuge should
be observed: screw, lid hings, latch and corrosion. In case of problems
contact the technicians. ▲

Chapter 4 Description and Performance

The IEC CL10 centrifuge was designed for laboratory use. Through
the application of the Relative Centrifugal Force (RCF), it allows the
separation of substances made of different density elements. Swing out
rotating equipment can generally carry a higher load than a fixed angle
or aerodynamical equipment. The larger the diameter of a rotor, the
greater the load and the lower the maximum rpm Relative Centrifugal
Force (RCF) generated on a centrifuged sample is directly proportional
to the sedimentation useful radius and to the speed value square.

A three phase asynchronous motor drives the rotating equipment. It is
situated in the center of an armours plated centrifugation chamber.

The centrifuge is equipped with a double interlock system that
prevents opening of the centrifuge lid when the rotor is spinning. The
centrifuge will not operate until the lid is closed and latched in place.
The lid remains latched until rotor stops spinning.

Note If a power failure occurs, access to the samples in the centrifuge is
possible.
For this it is necessary to use a special tool. Follow the lid opening
procedure emergency. ▲

Perform bypass under emergency conditions as the rotor could still be
rotating (see pag. 2-2).

The centrifuge is equipped with an accelerometric load imbalance
detector.

In case of excessive imbalance the machine stops whilst: this condition
is displayed with the message “INBL” which will disappear once the lid
has been opened to remove the imbalance cause (see 5.9).

The tolerated imbalance depends on the rotor in use. Carefully balance
sample load to avoid actuating the imbalance detection system.

Description and Performance

RCF Calculation

The main factors of the centrifuge action in terms of correct analysis
methodology are: the centrifugation time and the
gravity number “xg” (relative centrifuge acceleration) to which the
product is submitted. The graph allows the determination, as a
function of the radius “r”, of the relative centrifuge acceleration value,
expressed in multiples of the gravity acceleration value g (9.8 m/sec.)
for each RPM value between 150 and 20,000.

Example To find the relative centrifuge acceleration value xg of a point
at a 100 mm (0.1m) distance from the rotation axis and rotating at
3000 RPM, place a ruler on the radius scale on the left, joining the
point marked 100 on the left scale with the one marked 3000 on the
right hand scale of the RPM: the intersection of the central scale xg
gives directly the required relative centrifuge acceleration value (in our
case 1000 xg). ▲

The following relations connect the relative centrifuge acceleration and
the RPM number:

xg = 1,1178 • 10-3 • n2 • r where n = RPM

n = r = radius in meters

Chapter 5 Opreation Procdure

1. The presence of the operator is necessary from the start until
centrifuge reaches set speed.

2. It is necessary his presence also at the end of the centrifugation run.

1. By positioning the mains switch located on the right side of the
machine on I, the centrifuge is connected to the mains.

Front panel will be in the same “Operative Mode” as in the last
working cycle.

2. When the machine is stationary and with lid opening led on, it’s
possible to unlock the lid. The mechanical unlock, with subsequent
lid opening, is obtained by pulling towards the front of the unit the
handle on the centrifuge right side.

All rotating equipment are dynamically balanced at source; reference
numbers and marks indicate the exact respective positions of the
various parts forming the equipment; when rotating, this should always
be whole and complete (see fig. 1).

All buckets must be always inserted into the rotating equipment, even
for partial loads.

In the load balance operation, buckets should never be weighed, but
only their contents (adapters, tubes, etc.).

Distribute the load correctly. Loads should be inserted two by two, of
equal weight, at 180 degrees from the rotation axis and at equal
distance (radius) from the center of rotation (see fig. 2).

Loading balance

Figure 1.

For partial loads of swing-out rotating equipment (type O-) it is
advisable to distribute the tubes symmetrically also with regard to the
center of rotation (see fig. 3).

Correct Incorrest

Avoid overloading rotating equipment, having to centrifuge liquids
with higher density than 1200 kg/m3, the max. rpm should be reduced
according with the following formula:

Allowed rpm = Max. rpm

After having placed and locked the rotating equipment, lower the lid,
then close it pressing on the front edges until the hook in the lid clicks
into the lid lock mechanism. Only this operation will activate the
centrifuge-starting device.

Chapter 6

Hazards, Precautions and Limitation of Usa

• Centrifuging samples with higher density than allowed to the
maximum speed, without reducing the speed limit (see 5.2.6).

• Manipulating and/or tampering with the electronic and mechanical
parts.

En 61010-2-020 standard relative to laboratory centrifuges
recommends the user:

• To mark out a clearance envelope 300 mm around the centrifuge
or establish special procedures for the non entry of all persons or all
dangerous materials into this space during the operation of the
centrifuge.

• To provide an emergency stop switch enabling the mains power to
be cut in case of malfunction. The switch should be placed at a safe
distance from the centrifuge, preferably in a room different from
the one where the centrifuge is situated.

Thermo Electron rotors made of aluminium alloy are designed to
operate at their rated RCF for many years.
With careful use they will resist corrosion, lowing the possibility of
excessive imbalance, disruption and subsequent damage to the
instrument. The primary conditions for the initiation of corrosion exist
in every laboratory during daily use of the centrifuge. For this reason it
is essential that due care and attention be paid to inspection and
cleaning.

Chemical Corrosion

This corrosion is characterized by chemical reactions due to the
existence of any electrolyte liquid on the surface of the rotating
equipment.
If these substances are allowed to remain on the surface the corrosion
will almost certainly occurs. This produces first a discoloration of the
anodization the pitting of the metal.
Acidic and alkaline solutions sustaining their pH level will create
problems of corrosion in aluminium equipment.
Chlorides, present in salts or even in skin contact with the rotating
equipment are among the most aggressive and harmful substances
commonly found in the laboratory.
The chemical products, which are the origin of this corrosion do not
necessarily originate from broken tubes, for example they could come
from:

• chemical vapors present in the laboratory which are dissolved in the
residual humidity, in condensed water (refrigerated centrifuges)

present at the base of the rotor pockets.

• corrosive liquids originating from overfilled uncapped tubes (the
liquid overflowing during centrifugation)

• Inserts, adapters, racks, bottles whose exterior has been soiled by a
chemical product or poorly rinsed after decontamination (with
bleach, for example).

Note If the products are very corrosive, simply rinsing is insufficient.
Residual traces dissolve little by little with the humidity present in the
bottom of the rotor pocket. ▲

Beware of the presence of solid particles beneath tubes, inserts, racks
or adapters. These particles are crushed by the centrifugal force and
penetrate the protective, anodized layer of buckets and rotors, thus
creating easy pathways for corrosion. ▲

Stress Corrosion

This term relates to the phenomenon of accelerated corrosion due to
the effect of centrifugation when a corrosive chemical is in contact with
the alloy. From the time when the aluminium alloy has been attacked
by chemicals, stress corrosion begins to appear. As it is on a microscopic
scale it is even more dangerous than a macroscopic since it is invisible.

During centrifugation, chemicals responsible for corrosion are also
submitted to the very high “g” force, which pushes them against the
alloy. This close contact facilitates the chemical reaction which occurs
much faster than in a static situation. Moreover, centrifugal force is
very directional thus corrosion under stress creates, with a very small
amount of corrosive product, straight microscopic fissures. Each
centrifugation run makes the chemical migrate further and further.
Fissures or cracks, although it is microscopic, are a cut in the metal,
breaking the cohesion of the material. As one weak link in a chain
allows the chain to break, so the micro-fissures break the chain of
resistance of the accessory to centrifugal force. As accessories are
designed with high levels of safety, rupture does not occur as soon as
the first micro-fissures are produced.
Depending upon the location of the fissure, disruption may occur
before it reaches the external surface of the accessory. The fissure creates
a weakness, which makes the accessory less and less resistant to
mechanical fatigue.
The corrosion by a small amount of corrosive product does not disrupt
the accessory but makes it mechanically weaker and weaker until
disruption due to both centrifugal effort and number of cycles.

Chapter 6

Hazards, Precautions and Limitation of Usa

Warning Because stress corrosion is largely invisible, it is essential that
rotating equipment are scrutinized regularly paying particular attention
to susceptible parts such as the bottom of pockets, the outer edges and
the base of the rotating equipment. ▲

Thermo Electron centrifuges are likely to be used in medical research
and laboratory where hazardous substances are frequently present.

Warning The user has the responsibility for carrying out appropriate
decontamination and elimination of the handled materials.
Users should be aware on the internationally recognized “Laboratory
Biosafety Manual” , which gives information on decontaminants; their
use; dilutions; properties; and potential applications. ▲

If decontamination procedures require the use of warming (i.e.
autoclave) the rotating equipment should always be completely
disassembled before being subjected to heat and after external chemical
cleaning.
Seals, Tubes and plastic components should be decontaminated with
the method most suitable for them, which might not be the same as for
rotating equipment.

Note that the black color on the surface of the rotating equipment will
be gradually washed out if the rotor is regularly autoclaved or bleached.
This does not necessarily denote degradation on the anodization. ▲

Warning ANY PART, WHICH HAS BEEN SUBJECTED TO
TEMPERATURES ABOVE 130°C, MUST BE DISCARDED. ▲

Warning For any other unscheduled cleaning, the customer must
contact the manufacturer to verify that the proposed method does not
damage the appliance. ▲

Thermo Electron makes no claims as to the effectiveness of proprietary
brands of decontaminating solutions.

Chapter 7 Routine Maintenance

Caution During maintenance operations, always disconnect the

centrifuge from the mains (fig. 7.1). ▲

Regular cleaning of rotating heads and centrifugation chamber is vital for
correct work condition of the centrifuge (fig. 7.2).

The operator must wear suitable accessories during the cleaning (mask,
gloves, special wears ...).
Verify the integrity of biosafety components when they are used. The
substances used determinate also the correct methods for inspection of
these components.
However the user must verify always their good conditions also by
inspection. Do not clean with materials could damage silicone and
polycarbonate. The regular maintenance for biosafety is important for
daily life efficiency.
Ideally, rotating equipment should be washed after every run but at least
weekly in warm water containing a few drops of mild not alkaline
detergent (domestic washing up liquid is ideal) and EVERY TIME
AFTER A SPILLAGE HAS OCCURRED. Do not forget to wash the
core of the rotating head, which comes into contact with the drive
spindle. Each pocket of the rotating heads aerodynamics and bucket of
swing-out equipment must be washed thoroughly using a small nylon
brush. Once the rotating head has been removed, it is easy to clean the
centrifugation chamber and gaskets, warm water with not alkaline
detergent is recommended. Do not use corrosive solvents.
Once the Rotating Equipment is clean, rinse it by running water,
preferably distilled.
Dry the Rotating Equipment with a soft absorbent non-woven cloth or
tissue. Drying may be finished off with warm air jet (e.g. a hair dryer).

DO NOT USE METAL WIRE BRUSHES

AND MAKE CERTAIN THAT ROTATING HEADS

SLOTS AND BUCKETS ARE WELL-DRIED.

NEVER LEAVE damp Rotating Equipment on a metal surface,

particularly stainless steel because an electrochemical reaction could take
place with the aluminium or magnesium in the rotor. For swing-out
rotating equipment, be sure to clean the dirty grease from the studs and
replace it with a small amount of fresh grease. This will ensure the
buckets to swing easily. The vast majority of apparent imbalance
problems arise from the failure of the user to clean and grease the studs
and not from instrument error.

Routine Maintenance

Never apply grease if studs and balancing slots have not been carefully
cleaned (fig. 7.3 a/b). Use only the same kind of grease furnished in the
Rotating Equipment packaging.

For a correct cleaning a light domestic use detergent is recommended.
A mixture of 50% isopropilic alcohol and water is warmly suggested
because it will not damage the labels.

There are two fuses in the main tap.
You can change them drawing off from the main tap (see fig. 7.4)

Fuses dia 5 x 20 mm 2AT / 250V IEC CL10 (230V 50-60Hz)

Warning Before changing the fuses, disconnect the centrifuge from the
mains. ▲

In case of fuse blowing, do not replace them until the machine has
been inspected by a maintenance engineer.
