Tube Holder Configurations:
The Model 642E is capable of spinning test tubes up to 17 mm x 100 mm with
its horizontal rotor. Use the following chart and drawing to determine which tube
holder and cushion combination should be used with your application.
DIRECTIONS:
1.
Compare the tube to be spun with the three boxes shown below.
2.
Find the box that most closely matches the tube's length. NOTE: The
tube length with its stopper or cap must be shorter then the chosen
box or the tube will not fit properly in the tube holder.
3.
Match the letter from the chosen box with one of the configurations shown.
For Example: A tube is found to be as long as box B. Accordingly, we
can use a 100 mm tube holder with a 1525 cushion or a 75 mm tube
holder with no cushion, (configurations B1 or B2).

12. Push the 'OPEN / STOP' button. The 'RUNNING' indicator light should
go out and the motor should slow to a stop.

the machine unlocks prematurely, contact The Drucker Company for

Once the rotor has stopped, the interlock system will become
disengaged for sixty (60) seconds. The 'UNLOCKED' indicator light will
illuminate during this time.
14. To gain entry into the centrifuge after this period has ended, simply press
the 'OPEN / STOP' button. The lid will unlock for fifteen (15) additional
seconds.
After the centrifuge has passed this procedure it is ready for operation.
