Using The Optional Accessories; Adaptor For Small Sample Volumes - Elcometer 2300 Series Operating Instructions Manual

5 USING THE OPTIONAL ACCESSORIES

A number of optional accessories are available which will extend the capabilities of your
Viscometer. For ordering information, See "Spare parts and accessories" on page 28

5.1 Adaptor for small sample volumes

The adaptor for small sample volumes allows precise
measurement of the viscosity of small sample volumes
(8 ml to 13 ml). The adaptor is suitable for use with all
models of the Elcometer Rotary Viscometer.
There are two types of this adaptor:
• without an integrated temperature sensor
• with an integrated temperature sensor
Although the following instructions describe the version
which does not have an integrated temperature sensor,
they may also be used for the version which does have a
temperature sensor as it is very similar in design.
The adaptor consists of a water jacket, sample chamber
and a mounting bracket. Special spindles types TL or TR
are used with this adaptor.
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).
See also "Small volume samples adaptor kit" on page 28.
Viscosity range
Version L: 3 mPa•s to
Version R: 40 mPa•s to 3 300 000 mPa•s
Using the adaptor
1. Attach the appropriate spindle to the Viscometer motor drive coupling using the screwed
coupling and mounting hook.
2. 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.
3. 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.
4. Fit the end cap to the bottom of the stainless steel sample chamber.
5. Fill the sample chamber with a suitable volume of the fluid to be tested; 8 ml to 13 ml (0.27 oz
to 0.44 oz) - depending upon spindle.
6. Slide the sample chamber up into the water jacket and rotate to lock into position.
7. Fit the cover around the spindle hook and lower it onto the top of the sample chamber.
8. 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 small sample volumes is now ready to use.
