MODEL DESCRIPTION
DASH is a versatile line of centrifuges designed for STAT sample processing. Minimize lab error, reduce turnaround
time, and streamline training with the simple controls, powerful performance, and unique LED lid lighting system.
As a general purpose laboratory centrifuge, it is designed to also run other approved containers filled with
chemicals (non-flammable, non-explosive, non-volatile, and non-highly reactive only), environmental samples, and
other non-human body samples.
FEATURES
o
The first three (3) cycles are conveniently pre-set and labeled for you lab’s most common applications. Use the
default cycles or settings can be customized.
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
Up to 10 cycles can be programmed for time, speed, and braking and labeled with a custom name. Cycles can be
programmed by g-force (RCF) rather than speed (RPM) to facilitate matching validated cycles and manufacturers
IFUs.
o
A time and speed/g-force can be quickly entered for a single use cycle. The cycle will not be retained in memory.
o
If desired, the control panel can be temporarily locked on one cycle, ideal for standardization to a single spin.
o
A Preset Lock can be turned on to prevent changes from being made accidentally to programmed cycles.
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
The tube holders are fiber reinforced for high strength, durability, and years of trouble-free use.
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.
o
The lid safety system 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 warranties that this centrifuge is free from defects in workmanship and parts for 2 years.

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.
Opposing tube holders must be equally loaded or empty or loaded with equally weighted samples.
When loading only 3 tubes, they must be of equal weight.
Buckets can be placed around the rotor in any of the rotor loading configurations shown.
Each bucket must be loaded symmetrically with tubes as above.

Drucker Diagnostics – Customer Service: [phone] – [e-mail] | Page 11
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
centrifuge and should not need maintenance or servicing for the life of the centrifuge.
o
Tube Holder Replacement: It is recommended that the tube holders be replaced after 24 months of use.
Inspect tube holders regularly for cracks. If cracks are discovered, replace immediately.
o
Remove Accessories Before Moving: All tube holders, 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, tube holders, accessories and centrifuge exterior and void the warranty.
