MODEL DESCRIPTION
The SERO 12 is a compact, highly versatile centrifuge for use in blood banks and clinical laboratories. It is specifically
designed to minimize centrifugation time and simplify many basic test procedures, such as blood typing, manual
cell washing, cross-matching, genotyping, Coombs testing, and Ant-Rh titers.
This general-purpose laboratory centrifuge may also be used to spin approved containers with biologics, chemicals
(non-flammable, non-explosive, non-volatile, and non-highly reactive), and environmental samples.
FEATURES
o A digital cycle counter tracks the number of cycles the centrifuge has run.
o Lid lighting indicates the centrifuge’s status (ready, running, done), informing the operator when tubes are ready
for the analyzer and preventing tubes from being left in the centrifuge longer than necessary (patent pending).
o A traditional audible alert indicates the completion of the cycle. The audible alert can be muted.
o Cool–Flow design prevents overheating of samples by using ambient air to keep specimens at room temperature.
o A clear lid permits safe observation of samples and optical calibration of speed.
o The lid safety system prevents the centrifuge from operating unless the lid is closed and latched and only allows
entry into the centrifuge after the rotor has completely stopped.
o The high-power brushless motor provides years of operation with no routine maintenance.
INTENDED USE
General purpose laboratory centrifuge, intended for the density-based separation of fluids through centripetal
acceleration.
WARRANTY
Drucker Diagnostics warrants that this centrifuge is free from defects in workmanship and parts for 2 years.

APPLICATIONS
The SERO 12 has been designed to facilitate blood testing procedures involving centrifugation, incubation, and cell
washing with minimal tube handling. Many procedures can be performed entirely without removing tubes from the
centrifuge rotor, thus reducing the possibility of errors in transferring tubes. The following notes on use of the SERO
12 are intended to set practical guidelines for the technologist. When possible, refer to the manufacturer’s I.F.U.
AGGLUTINATION TESTS
Whenever possible, it is important that the anti-serum manufacturer’s instructions be followed on recommended
time periods for centrifuging cells with their sera in the SERO 12.
NOTE:It is recommended that the optimum centrifugation period be determined by controlled reactions using
known cells. This method is the easiest way to determine time necessary to produce the desired tightness of
agglutination.
INCUBATION
Many blood testing procedures require incubation at 37°C before and after centrifugation. The SERO 12 rotor has
been designed to allow the incubation of these reactions without removing the tubes. You may lower the entire
rotor into a water bath for the test being performed. When the rotor is removed, water will drain through the
perforations in its base. Allow the water to drain completely prior to transporting tubes.
CELL WASHING
The SERO 12 rotor may be conveniently used for many tests that require single or multiple blood cell washings.
Because the tubes are maintained at an angle of 45° during centrifugation, the centrifuge is highly efficient in
washing cells. The cells are deposited quickly after sliding down the angled tubes.
After the button is formed, the supernatant solution can be readily poured off all tubes simultaneously. This is done
by removing the rotor from the drive spindle immediately after it stops spinning, placing the retainer ring around
the tubes, and inverting the rotor.

INITIAL SETUP
o Unpack and verify that all the following are included:
• Centrifuge
• Power cord
• Quick Start Guide
o Setup the centrifuge on flat and level surface. A bench top clearance height of 21” (54 cm) is required to open
the lid.
o The centrifuge should have 6” (15 cm) of clear space around the centrifuge. Proper ventilation is necessary to
prevent the overheating of samples as well as premature failure of the centrifuge. Choose an area which allows
unencumbered air flow, and where the temperature remains between 16°C and 32°C.
o No hazardous material shall be permitted in the clearance envelope during operation.
o The operator time within the envelope shall be limited to the time necessary for loading, unloading, and
centrifuge operation only.

BALANCING LOADS
Your centrifuge must contain a balanced load to work properly. Spinning balanced loads will extend the life of the
centrifuge and produce better results. Use the following rules when loading the rotor. If an odd number of samples
is to be spun, fill a tube with water to match the weight of the unpaired sample and place it across from this sample.
6 Tubes
12 Tubes

Drucker Diagnostics – Customer Service: [phone] – [e-mail] | Page 12
CARE AND PREVENTATIVE MAINTENANCE
With proper care and maintenance, your centrifuge will provide years of laboratory service. For proper care, the
following steps should be taken:
o Always Spin Balanced Loads: Make certain that you are always spinning a balanced load, as shown in the
previous section. These centrifuges have a unique counter balanced motor mounting design which produces
excellent vibration dampening. However, out–of–balance loads may break glass test tubes and may produce
unsatisfactory separation results. Proper load balancing will improve sample separation and extend the life of
the centrifuge.
o Motor and Electrical Maintenance: The highest quality electrical components have been selected for the
centrifuges and should not need maintenance or servicing for the life of the centrifuge.
o Remove Accessories Before Moving: All tubes, samples, and caps must be removed from the rotor chamber
before transporting or storing the centrifuge to prevent damage and injury.
CLEANING AND DISINFECTION
To prolong the life of the centrifuge, cleaning and disinfection is recommended every six months or whenever there
is a spillage or tube breakage. Contaminants must be removed immediately, or corrosion and premature
degradation of components can occur. Before using any cleaning or decontamination methods other than those
recommended by the manufacturer, users should verify with the manufacturer that the proposed method will not
damage the equipment.
o Unplug the centrifuge before cleaning.
o Use appropriate personal protective equipment (PPE).
o Apply cleaning solutions with a towel or cloth. Do not submerge the centrifuge in water or other cleaning
solutions as this will cause damage and void the warranty.
o ONLY isopropyl alcohol or a 10% (5500 PPM) bleach solution should be used to disinfect the centrifuge and its
accessories.
o All surfaces must be dried immediately after cleaning and disinfecting.
TBQ GERMICIDAL PRODUCTS ARE NOT RECOMMENDED AS THEY MAY CAUSE DAMAGE TO THE
CENTRIFUGE.REFRAIN FROM USING TO PREVENT VOIDING THE WARRANTY.
o Fully/partially halogenated hydrocarbons, ketones, esters, ethers, benzyls, ethyl benzenes, and all other
chemicals not prescribed by the manufacturer shall not be used as they may cause damage to the rotor chamber,
rotor, accessories, and centrifuge exterior and void the warranty.
