MODEL DESCRIPTION

DASH is a versatile line of centrifuges designed for STAT sample processing. Minimize lab error, reduce turnaround time, and streamline training with simple controls, powerful performance, and a 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

• The first three (3) cycles are conveniently pre-set and labelled for your lab’s most common applications. Use the default cycles or settings can be customized.
• 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).
• Up to 10 cycles can be programmed for time, speed, and braking and labelled with a custom name.
• Cycles can be programmed by g-force (RCF) rather than speed (RPM) to facilitate matching validated cycles and manufacturers’ IFUs.
• A time and speed/g-force can be quickly entered for a single-use cycle. The cycle will not be retained in memory.
• If desired, the control panel can be temporarily locked on one cycle, ideal for standardization to a single spin.
• A Preset Lock can be turned on to prevent changes from being made accidentally to programmed cycles.
• A traditional audible alert indicates the completion of the cycle. The audible alert can be muted.
• CoolFlow design prevents overheating of samples by using ambient air to keep specimens at room temperature.
• The tube holders are fibre-reinforced for high strength, durability, and years of trouble-free use.
• A clear lid permits safe observation of samples and optical calibration of speed.
• The lid safety system prevents the centrifuge from operating unless the lid is closed and latched.
• The lid safety system only allows entry into the centrifuge after the rotor has completely stopped.
• The high-power brushless motor provides years of operation with no routine maintenance.

INTENDED USE

INITIAL SETUP

• Unpack and verify that all the following are included:
  • Centrifuge
  • Power cord
  • Tube holders
  • Quick Start Guide
• Set up the centrifuge on a flat and level surface. A bench top clearance height of 21” (54 cm) is required to open the lid.
• 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 that allows unencumbered airflow, and where the temperature remains between 16°C and 32°C.
• No hazardous material shall be permitted in the clearance envelope during operation.
• The operator time within the envelope shall be limited to the time necessary for loading, unloading, and centrifuge operation only.
• Plug the line cord into the centrifuge.
• Plug the line cord into an approved electrical outlet.
• Turn on the power switch on the back of the centrifuge.
• BE SURE THE ELECTRICAL OUTLET IS ALWAYS ACCESSIBLE AS THE LINE CORD IS THE MEANS OF EMERGENCY DISCONNECTION!

OPERATION

• Place the tubes into the tube holders. Be sure to follow the rules for balanced loads as listed on page 10.
• Close the lid and turn the lid knob clockwise to its complete stop position.
• The digital screen shows the currently selected cycle. To select another cycle, press the UP or DOWN button in succession until the desired cycle is selected.
• Pushing the START button on the control panel will start the spin cycle.
• When the cycle is completed, the rotor will slow to a complete stop and the lid light will flash.
• The unlocking mechanism will engage for 60 seconds allowing entry into the rotor chamber.
• To unlock after more than 60 seconds have elapsed, press the UNLOCK button. The lid will unlock for another 15 seconds.
• Turn the lid knob counterclockwise and open the lid. The lid light will turn off. You may now safely remove the samples.

DELETING A CYCLE

CYCLE LOCK

To ensure repeatability, the centrifuge can be locked either on one cycle (Single Cycle Lock) or restricted to the saved cycles (Preset Lock). The Single Cycle Lock also prevents making changes to the selected cycle parameters. The Preset The lock allows the selection of any saved cycle and prevents changing the parameters of saved cycles.

PRESET CYCLES

| Mem- 1| Mem- 2| Mem- 3
---|---|---|---
RPM| 4,300| 4,300| 3,500
Time| 5 min| 6 min| 7 min
Brake| 6| 3| 3

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. 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 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:
• 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 counterbalanced 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.
• 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.
• 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 them immediately.
• 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 are 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.

• Unplug the centrifuge before cleaning.
• Use appropriate personal protective equipment (PPE).
• 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.
• ONLY isopropyl alcohol or a 10% (5500 PPM) bleach solution should be used to disinfect the centrifuge and its accessories.
• 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.
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.
