Safety and handling 2 2.3

General safety instructions

ELECTROCUTION During maintenance operations, when the DiaCent-12 is powered and its lid is removed, the instrument may not be left without watch.

INFECTION There is a risk of infection from skin contact with blood samples. Always wear protective gloves when working, in accordance with laboratory safety regulations.

The initial operation may only be carried out by engineers who, as a result of their training and experience, are familiar with the initial operation and the operation of laboratory instruments. Maintenance and repairs may only be performed in conformance with the instructions and by the technical personnel authorised by the manufacturer. The sole possession of the Service Manual does not allow the personnel to perform any kind of repair on the DiaCent-12. Take into account all the warnings and follow all the instructions displayed on the DiaCent-12 and which are printed in the documentation. It is mandatory to use the products specified in the present User Manual to clean the DiaCent12. If you plan to use another product, only do so after having obtained the authorisation of the manufacturer. Using materials other than those defined in the User Manual (unauthorised dangerous goods for instance) is forbidden. Breaking this rule will be considered by the manufacturer as guilty negligence. Never try to use replacement pieces other than those authorised by the manufacturer of the DiaCent-12. The centrifuge must not be operated with an open protective lid due to the risks of injury when the head is rotating.

2 Safety and handling

The DiaCent-12 must be used on an appropriate table (See section “4.1 Unpacking and setting up the ID-Centrifuge” on page 27). Ensure that the ventilation around the DiaCent-12 is sufficient to avoid any excessive heating. A space of 300 mm all around the DiaCent-12 must be left clear of any obstacle. The DiaCent-12 must only be used with accessories approved by the manufacturer (example: ID centrifuge head). Do not operate the centrifuge in the case of damage or switch off immediately. Switch off the power switch and remove the power plug from the power supply! Mark the centrifuge as defective to prevent further use. The DiaCent-12 may not be used in combination with other machines. The manufacturer’s agreement must be obtained before using the DiaCent-12 in conjunction with other equipment.

Use the cleaners mentioned in the User Manual for cleaning the centrifuge. Other cleaners should be used only after consulting the manufacturer. Switch off the power switch and remove the power cord from the power supply when cleaning the centrifuge or when replacing the fuse. Repairs must be carried out by authorised personnel. Do not try to start up the centrifuge yourself (except when indicated by directions in the User Manual). Owning a Service Manual does not mean you are authorised to carry out repairs on the centrifuge. The manufacturer offers special training courses for repairing the DiaCent-12. You can obtain information from your Bio-Rad representative or manufacturer. This User Manual must always be accessible to all personnel working with the ID-Centrifuge. Never let any liquid enter the system. In case of liquid spill inside the instrument, act immediately as follows:

A.

Switch off the instrument using the main switch.

B.

Unplug the power cord.

C.

Dry up the instrument.

D.

Clean and decontaminate the instrument.

E.

Check all its electrical functions.

For further information, please contact your Bio-Rad dealer or the manufacturer.

2.3.1

Observations and information In case of defective operation or any other technical incident for which no remedy is described in this manual, please contact immediately the manufacturer or your dealer. Safety measures ordered by the manufacturer are mandatory.

B.

Fill in a decontamination certificate after decontamination. You can find a form for the decontamination certificate in the appendix at the end of this manual.

C.

Make a copy of the decontamination certificate and keep the original together with the centrifuge.

D.

Note the instructions in chapter “2.5.2 Handling and transportation” on page 18 before transporting the centrifuge.

2.5.1.1

Storage If the centrifuge is temporarily stored in a laboratory environment, complete packing is normally not required. However, if the centrifuge is stored in a storage room, basement or similar area for a longer period of time, we recommend that you pack it completely to protect it.

Description 3

Chapter contents This chapter describes the design and function of individual modules of the DiaCent-12 including the operating and display panels as well as the basic principles of the process.

3.1

Principles of the process The centrifugation of blood samples is carried out in order to assist in the separation of the plasma or serum from the erythrocytes prior to carrying out certain analysis techniques. Direct and indirect antiglobulin tests (DAT, IAT) using the sample tube centrifugation technique also involve centrifugation phases following the addition of anti-human globulin (AHG). Compliance with the centrifugation parameters specified for the test is particularly important, in order to ensure sufficient sensitivity of the entire DAT or IAT process. Centrifugation which is too weak following the addition of AHG does not result in optimal agglutination, while centrifugation which is too strong produces a sediment which sticks firmly to the sample tube (clumps of erythrocytes). This means that excessive shaking is required in order to release this sediment from the bottom of the sample tube. Mechanical stress of this kind may result in the loss of weak or unstable agglutinates. The DiaCent-12 therefore offers the possibility of adjusting the centrifugation parameters in order to ensure optimal conditions for the separation of erythrocytes from serum or plasma and for antiglobulin tests using sample tube centrifugation or other immunohaematological processes which require a centrifugation phase during the test process.
