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.
