General

The Centorr Series 3 Crystal Puller was developed to meet the specific requirements of scientists and researchers needing a dependable, multi-purpose crystal puller.

Originally designed for use with Centorr high temperature vacuum or controlled atmosphere furnaces, the Centorr Model 3 Crystal Puller has also found a significant market as a separate unit because it readily adapts to a user's existing furnace. The standard puller includes a mounting table for Centorr Series 5 Tri-Arc, Series 15 Laboratory or other small furnaces. Table is adjustable, by simply loosening hand knob on clamp column, for accurate alignment and operation of puller with these and other furnaces which will fit within the large clearance space provided.

Very slow slide speeds can be confirmed by observation of gear system through plexiglass window.

Aluminum and stainless steel components utilized in the construction of this puller make a strong, yet relatively lightweight unit.

The crystal puller drive mechanism is housed in an attractive cabinet with electrical controls conveniently located on front panel.

The puller slide motion is controlled by:

Drive selector switch:
1. Fast up
2. Slow on
3. Fast down
Slow drive torque selector switch:
