5.3 Adaptor for helical movement
The adaptor for helical movement allows precise
measurement of the viscosity of samples such as
cream, gel, wax, paste, putty, gelatine, etc. The
adaptor is suitable for use with all models of the
Elcometer Rotary Viscometer.
The adaptor moves the Viscometer head slowly up
and down. This movement causes the spindle to
trace a helical path through the sample, therefore
avoiding the creation of voids in the sample which
would otherwise make measurement impossible.
The adaptor consists of:
• drive mechanism with head mounting bracket
and mains lead
• spindle clamp/coupling and weight
• spacer tube
• ring clamp, x 2
• set of P series spindles
water jacket, sample chamber, a mounting
bracket, a column extension piece and a special
cylindrical spindle (LCP).
The adaptor is used with special T-type spindles -
PA, PB, PC, PD, PE, PF

page 29.
Viscosity range
Version L: 156 mPa•s to 3 120 000 mPa•s
Version R: 1660 mPa•s to 33 300 000 mPa•s
Using the adaptor
1. Remove the standard head mounting bracket from the column.
2. Slide the spacer tube (A) onto the column until it rests on the base.
3. Slide one of the ring clamps (B) onto the column.
4. Press and hold lever (C) of the drive mechanism upwards and slide the drive mechanism (D)
onto the column. Release lever (C) to engage the drive mechanism with the column.
