SPINNING BALANCED LOADS

Your centrifuge must contain a balanced load in order to work properly. Use the following rules when loading the rotor. Spinning balanced loads will extend the life of the machine and produce better results.

1. Opposing tube holders must be identical and must contain the same cushion, or none at all.
2. Opposing tube holders must be empty or loaded with equally weighted samples.
3. 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.

ROTOR REMOVAL AND INSTALLATION

TO REMOVE THE ROTOR

1. Unlock the centrifuge by pushing the ‘OPEN / STOP’ button and unlatch and open the lid.
   CAUTION: Unplug the centrifuge from the electrical outlet to eliminate the possibility of electrical shock or other injury.

2. Remove the test tube holders.

3. Remove the nut in the center of the rotor by turning it counterclockwise (a tool may be required).

4. The rotor is sitting on a cone-shaped adapter. Pull the rotor up and off of this adapter.

TO INSTALL THE ROTOR

1. Place the rotor back onto the cone-shaped adapter. You may need to turn the rotor slightly to line it up properly.
2. The rotor should slide onto the rotor cone freely.
3. Once a proper fit has been achieved, replace the nut and turn it until it is hand-tight, (a tool may be required).
4. Replace the tube holders and verify that they are seated properly.
5. It is recommended that the initial setup procedures be performed to ensure that the rotor has been installed correctly and that no damage has been done to the centrifuge during either the rotor installation or possible rotor chamber cleaning. See page 4 for this procedure.

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

1. Provide Adequate Ventilation: For cooling purposes, the Model 642M draws in ambient air through the air intake cover on the top of the lid and exhausts this air in the rear of the base. The centrifuge should be placed on a hard smooth surface for good air circulation.
2. Always Spin Balanced Loads: Make certain that you are always spinning a balanced load. The Model 642M has a unique counter balanced motor mounting design which, along with its rubber suction feet, 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. Refer to page 10 on balanced loads for additional information on balancing the load.
3. Keep the Tube Holders Clean: NOTE: Always follow the safety guidelines of your laboratory to properly clean up and/or dispose of materials in the event that a substance known to be potentially toxic, radioactive or contaminated with a pathogenic microorganism is spilt in or on the centrifuge. Small glass fragments left in the tube holder after a tube breakage may adhere to the next test tube inserted in that holder. When this tube is handled, these fragments may puncture protective gloves and lacerate the operator’s fingers or hand. Remaining fragments may provide stress points on subsequent tubes and result in additional breakage. If a tube breakage occurs, carefully remove the tube holder. Properly dispose of the sample and tube fragments and thoroughly clean both the inside and outside of the tube holder. Insert a new tube cushion (if necessary) and replace the tube holder in the rotor.
4. Motor and Electrical Maintenance: The Model 642M uses a brushless permanent split capacitor AC motor. It should not need routine servicing for the life of the centrifuge. The electrical components are selected for high reliability and should not need routine service.
5. 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.
6. 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.

1. Unplug the centrifuge before cleaning.
2. 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.
3. NLY isopropyl alcohol, soap and water, or a 10% (5500 PPM) bleach solution should be used for cleaning and disinfection of the centrifuge and accessories.
4. All surfaces must be dried immediately after cleaning and disinfecting.
5. TBQ Germicidal products shall not be used, as they will cause damage to the centrifuge and void the warranty.
6. The use of 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.
7. It may be necessary to remove the rotor and clean the rotor chamber. Follow the instructions on page 9 to remove and reinstall the rotor.

TRANSPORTATION
During transportation, accessories can become dislodged from the rotor and fall into the rotor chamber where they can remain unnoticed. Before transporting the centrifuge in a vehicle, make certain that the centrifuge is secured sufficiently to prevent shifting sliding or rolling, and there are no tube holders or accessories in the rotor or rotor chamber.

TROUBLESHOOTING

Note: The latch must be turned completely clockwise to its stop position in order for the centrifuge to operate.

EMERGENCY ROTOR CHAMBER ENTRY

In the event of power failure, it may be impossible to unlock the lid by conventional means. In this case, entry into the rotor chamber may be made by removing the latch label and using a pen to manually disengage the locking mechanism (see photo). Pull the mechanism towards the control panel and then unlatch and open the lid. If the unit is damaged, contact your authorized dealer or Drucker Diagnostics.

CALIBRATION TESTING
It is recommended that the top speed be tested every two years for continued safe operation. Contact Drucker Diagnostics for further information or testing availability.

SAFETY

The Model 642M complies with US, Canadian, and European Safety standards.

• The centrifuge should be placed on a stable, flat surface.
• Before using the centrifuge, check the rotor. Do not operate the centrifuge if the rotor is loose, or does not rotate freely.
• Rotors and accessories that show evidence of damage or corrosion or are to be taken out of service.
• The centrifuge must be taken out of service if safety related damages are found in the rotor chamber.
• Do not open the lid until the rotor has come to a complete stop.
• For use only on smooth level surfaces, or approved stands.
• Do not move the centrifuge while it is plugged in or running.
• Do not operate the centrifuge in a moving automobile.

Lid Safety Switch: The Model 642M lid is secured to the top of the cabinet by a latching knob and pawl system. When the knob is rotated clockwise, the pawl grips the underside of the cabinet opening and prevents the lid from opening. A mechanical stop positions the pawl and prevents it from rotating completely. When rotated to the stop position, the pawl makes contact with a micro– switch mounted underneath the cabinet top. The lid safety switch prevents the centrifuge from operating while the lid is open. An indicator light on the front of the machine will light up when the lid has been latched properly.

Lid Safety Interlock System: In addition to the Lid Safety Switch, the Model 642M has a true “0 RPM” lid locking system. The lid safety locking system keeps the lid locked at all times, (even during power failure), and requires that the rotor be at rest in order to unlock the lid. The centrifuge will not allow entry into the rotor chamber unless the centrifuge has power and the rotor is stopped. To open the lid, make sure that the centrifuge is plugged in and, with the rotor stopped, press the ‘OPEN / STOP’ button.

Note: After the centrifuge has started spinning, it may be possible to rotate the lid knob enough to cause the pawl to lose contact with the lid safety switch. If this happens, the centrifuge motor may lose power, but the lid will still remain locked. If the knob is accidentally moved and this situation should occur, rotate the knob fully clockwise to its stop position and the centrifuge will resume operation.
