Table of contents

The Centrifuge 5424 is a non-refrigerated bench-top centrifuge. It is intended for sample preparation within the sphere of clinical diagnostics and in the routine, training and research laboratory in hospitals, science and industry. The devices may only be operated by trained specialist staff.

The various ﬁxed-angle rotors and adapters enable a large number of tubes like micro test tubes, PCR strips, Microtainers® and Spin Columns to be used. In the context of in vitro diagnostics, the Centrifuge 5424 is designed among other things for chromosome analysis of human cells by the FISH technique (Kievits et al. 1990).

Before using the centrifuge 5424 for the ﬁrst time, please read the manual. The latest version of the manual and the safety instructions in your language can be found on the Internet at www.eppendorf.com.

1 Introduction

You will see this symbol on your centrifuge and at a number of points throughout this

manual. The texts it highlights are relevant to safety. Use the centrifuge only when you have read these safety instructions.

1.1 Delivery package

5424 000.428, 5424 000.029, 022620428, 022620461, 022620401 and 022620444)

1.2 Installing the device

– To disconnect the power supply of the centrifuge from the power supply in the

event of a fault, an emergency switch must be provided away from the centrifuge, preferably outside the room in which the centrifuge is located or next to the exit from this room.

– Remove the transport safety device and keep it together with the centrifuge pack-

aging for possible use if the device is subsequently moved.

– Place the centrifuge on a solid, ﬂat, non-resonant lab bench. Check beforehand

whether the lab bench is speciﬁed for the weight of the centrifuge.

– The surrounding area must be well-ventilated and protected against direct sunlight.

To ensure that ventilation of the device is not impaired, a minimum fundamental clearance of at least 30 cm to the side and at least 15 cm to the back wall must be maintained.

– During centrifugation, according to the recommendations set out in EN 61010-2-020,

a safety clearance of 30 cm must be maintained around the centrifuge within which there are no objects which may be destroyed and so cause further damage.

– Please ascertain that the power supply and the power frequency are compatible

with the information given on the device ID plate.

1 Introduction

– Now connect the centrifuge to the power supply and switch it on at the main power

switch (see inside cover page). The centrifuge is now ready for operation and the display is active.

– Before starting for the ﬁrst time, check whether the rotor and the rotor lid are

tightened in accordance with speciﬁcation. To tighten the rotor, place the rotor key supplied on the rotor nut and turn it clockwise until the rotor nut is ﬁrmly tightened up. The rotor lid is then tightened up.

Introduction

2 Safety precautions and applicational limitations

For your personal safety, please be sure to comply with the following regulations

unconditionally.

– The centrifuge 5424 must only be used for the speciﬁed applications (see Section 1,

“Introduction”). It must not be operated in explosive atmospheres. Explosive, radioactive

Safety precautions and applicational limitations

or highly reactive substances must not be centrifuged.

– When being moved from the cool room to a normal lab environment, the centrifuge must

either run for half an hour in the cool room ﬁrst to warm up, or it must warm up for at least 3 hours in the lab before being connected to the power supply system, in order to prevent damage from condensation.

– The centrifuge must not be moved or knocked while in operation.

– Centrifuges which have not been properly installed or repaired may not be operated.

Repairs may only be carried out by Service personnel authorized by Eppendorf. Use only original Eppendorf spare parts and rotors.

– When handling toxic liquids or pathogenic microorganisms of risk group II (see World Health

Organization: Laboratory Biosafety Manual) comply with the relevant national regulations. Bioseals are a component of biosafety systems which are not capable, in isolation, of ensuring that people and the environment are protected when pathogenic microorganisms are being handled. When working with pathogenic microorganisms of a higher risk group, more than one aerosol-tight bioseal must be provided for. If the named liquids are spilled in the rotor or rotor chamber, the centrifuge must be thoroughly and professionally cleaned. Before using any cleaning or decontamination method other than that set out in Section 4, "Maintenance and cleaning", please consult Eppendorf to ensure the intended method will not damage the device.

– Rotors and rotor lids must always be properly secured. The centrifuge may only be

operated with the rotor and rotor lid ﬁrmly tightened. To do this, before centrifugation, place the rotor key supplied for tightening up the rotor on the rotor nut and turn it clockwise until the rotor nut is ﬁrmly tightened up. The rotor lid is then screwed on tightly (see Section 3.5 "Rotors" with regard to exceptions for rotors FA-45-24-11 and

FA-45-24-11-Special for centrifuging micro test tubes with closed tube lids). If unusual noises occur when the centrifuge starts, the rotor or the rotor lid are not properly secure. In this case, stop centrifugation immediately using start/stop.

– The rotor may only be loaded symmetrically. Opposing vessels should be of the same type

and be ﬁlled equally. On each rotor you will ﬁnd information about maximum load (adapter, tube and contents) per bore - this limit may not be exceeded.

– Rotors showing clear signs of corrosion or mechanical damage must not be used. Check

the accessories regularly.

2 Safety precautions and applicational limitations

– Rotors are high-grade components which have to withstand extreme stresses and strains.

Aluminum rotors are surface-treated to provide them with a high level of protection from corrosion by the most common laboratory chemicals, though this protection is not unlimited. Avoid damage from the use of aggressive chemicals such as strong and weak alkalis, strong acids, solutions of mercury, copper and other heavy metal ions, chlorinated hydrocarbons, concentrated salt solutions and phenol. If the rotor is contaminated by aggressive substances, clean it immediately with a neutral agent (e.g. Extran® neutral, RBS® neutral or Teepol® 610 S). This applies to the rotor bores in particular. Rotors labeled "coated" are particularly resistant to chemicals. However, even on these rotors, this does not replace regular cleaning as described in Section 4 "Maintenance and cleaning". Protect the rotors from mechanical damage. Even minor scratches or cracks can result in serious internal material damage.

– The material being centrifuged may not exceed a density of 1.2 g/ml at maximum speed.

– If the rotor is run for a lengthy period or more often with short centrifugation runs, the sam-

ple tubes will become hot.

– Keep within the load limits speciﬁed for the tubes by the tube manufacturer. Tubes may only

be centrifuged at the preselected g-force (rcf) if they are approved for this application by the manufacturer.

– Before centrifugation, all the tubes should be subjected to a visual inspection for material

damage. Damaged tubes must not be centrifuged, as if tubes break, there may be further damage to the centrifuge and its accessories in addition to loss of the sample.

– Tube lids must be sealed down tight before centrifuging. The lids of tubes which are not

sealed may rip off during centrifugation and damage the rotor lid and the centrifuge.

– When using organic solvents (e.g. phenol, chloroform), the durability of plastic tubes may be

impaired with the result that tubes may break during centrifugation.

– When closing the centrifuge lid, do not place your ﬁngers between the lid and the centri-

fuge, otherwise they may be trapped.

– The transparent rotor covers made from polypropylene have a maximum useful life of 3

years. The date of manufacture is impressed on them in the form of a watch .

Rotors and rotor covers which have been damaged chemically or mechanically or which have passed their maximum useful life must no longer be used.

Safety precautions and applicational limitations

Declaration concerning the ATEX directive (94/9/EC)

The present design and ambient conditions inside Eppendorf centrifuges mean that they are not suitable for use in a potentially explosive atmosphere. The centrifuges must therefore only be used in a safe environment such as the open environment of a ventilated laboratory or a fullyextracted fume hood. The use of substances which may contribute to a potentially explosive atmosphere is not permitted. The ﬁnal decision on the risks in connection with the use of such substances is the responsibility of the user of the centrifuge.
