MODEL DESCRIPTION

HORIZON is a versatile line of centrifuges designed with 3 settings to process Chemistry, Coag or Platelet Poor Plasma, and Urine specimens in the same unit. The  maximum g-force of 2,000 xg makes HORIZON suitable for wide variety of applications. Cycle settings can be changed to accommodate custom settings.
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 The first three (3) cycles are conveniently pre-set and labeled for your lab’s most common applications. Use the default cycles or customize them as needed.
o If desired, the control panel can be temporarily locked on one cycle for error-free reproducibility and ideal for standardization to a single spin.
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 to  facilitate matching validated cycles and manufacturers IFUs.
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 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.

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.

12-TUBE CENTRIFUGES

24-TUBE CENTRIFUGES
Buckets can be placed around the rotor in any of the rotor loading configurations shown below. Each bucket must be loaded symmetrically with tubes.

15 mL / 125 mm tubes may be spun in the standard HORIZON 24 Flex buckets, but must be loaded as follows:

When three buckets are being used, each bucket must be loaded symmetrically in any configuration below:

When all six buckets are being used, the rotor must be loaded in the following configuration only. Opposing buckets do not need to be filled but must be loaded in exactly the same way.

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 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.
WIPE OFF THOROUGHLY AFTER USE 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.

TROUBLESHOOTING
