5.2 Adaptor for low viscosity samples

The adaptor for low viscosity samples allows precise
measurement of the viscosity of low viscosity samples
(16 ml to 18 ml), both Newtonian and non Newtonian. The
adaptor is suitable for use with all models of the Elcometer
Rotary Viscometer.
There are two types of this adaptor:
• with water jacket - for indirect heating up to 100°C
(212°F)
• without water jacket - for sample temperatures up to
200°C (392°F)
Although the following instructions describe the version
which has a water jacket, they may also be used for the
unheated version which is very similar in design.
The adaptor consists of a water jacket, sample chamber, a
mounting bracket, a column extension piece and a special
cylindrical spindle (LCP).
Water from an external heating bath is circulated through
the jacket surrounding the sample chamber; this allows the
sample to be maintained precisely at a set temperature of
-10°C to 100°C (14°F to (212°F).
For ordering information see "Low viscosity adaptor kit -
with water jacket" on page 28 and "Low viscosity adaptor kit
- without water jacket" on page 28.
Viscosity range
Version L: 0.5 mPa•s to
Version R: 4.8 mPa•s to 21 333 mPa•s
Using the adaptor
1. Fit the extension piece to the column. This raises the Viscometer head sufficiently to allow the
adaptor for low viscosity samples to be used correctly.
2. Attach the LCP spindle to the Viscometer motor drive coupling using the screwed coupling and
mounting hook.
3. Attach one end of the mounting bracket to the water jacket, as shown; note the locating pin
which allows the bracket to be attached the correct way only.
4. Slide the water jacket slowly and carefully over the spindle and then attach the other end of the
bracket to the head of your Viscometer.
5. Fit the end cap to the bottom of the stainless steel sample chamber.
6. Fill the sample chamber with a suitable volume of the fluid to be tested; 16 ml to 18 ml (0.54 oz
to 0.61 oz).
7. Slide the sample chamber up into the water jacket and rotate to lock into position.
8. Fit the cover around the spindle hook and lower it onto the top of the sample chamber.
9. Connect the external heating bath to the water jacket inlet and outlet and then leave it
operating for a sufficient amount of time for the temperature of the sample to stabilise.
The adaptor for low viscosity samples is now ready to use.
