Tube Holder Congurations:
The 642VFD 230V is capable of spinning test tubes up to 17mm x 100mm 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 t properly in the tube holder.
3. Match the letter from the chosen box with one of the congurations shown.
