Model Description:

The Model 642E is a continuous-duty, electronically-controlled horizontal

centrifuge with a lid safety interlock system. The unit is controlled by an electronic push–button timer that has been preset for ten (10) minutes, for precise spin times and ease of use. Samples can be safely viewed through the transparent lid. Entry into the machine is restricted during operation by the safety interlock system. The Model 642E features a lighted control panel that displays the status of the machine, easily viewable from a distance.

For warranty information, turn to page 12.

WARNING: For the safety of both the operator and service personnel, care should be taken when using this centrifuge if handling substances that are known to be toxic, radioactive or contaminated with pathogenic microorganisms. When Risk Group II materials are used, (as identied in the World Health Organization “Laboratory Bio-Safety Manual”), a Bio-Seal should be employed. The Bio-Seal accessory for the model 642 tube holders is the non-aerosol shield cap, p/n 7713011. In the event that materials of a higher risk group are being used, more than one level of protection must be provided. The use of ammable or explosive materials as well as those materials which have a vigorous chemical reaction is prohibited. For your safety and the durability of your machine, never transport or store centrifuge with tube holders inside machine.

Intended Use:

General purpose laboratory centrifuge for sample separation.

Supplied Equipment*:

The following items come standard with each Model 642E centrifuge:

The Horizon Model 642E complies with all requirements of UL standard 61010A-1, 61010A-2-20; Can/CSA C22.2 No’s

1010.1; 1010.2.20.

Safety:

Lid Safety Switch: The Model 642E 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 642E has a true “0 RPM” lid locking system. The lid safety interlock 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.

Circuit Breaker: The Model 642E is protected with a 4 Amp circuit breaker located at the rear of the machine mounted to the base. Any electrical short circuit will cause the breaker to cut power to the machine.

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 The Drucker Company.

Calibration and Earth Ground Testing:

It is recommended that the top speed, ground continuity and line leakage be tested every two years for continued safe operation. Contact The Drucker Company for further information or testing availability.
