Brookfield UL Adapter - Manual (Page 2)

Brookfield Engineering Laboratories Inc. - 2 - Operating Instructions M/91-080-I1003
Assembly & Operation
1. Attach the mounting channel to the viscometer by threading the upper mounting screw into the
viscometer pivot cup. Do not overtighten. The end of the mounting channel with the pin must be at the
bottom, as shown in Figure 1 and 2.
2. Assemble the ULA spindle, SXV-8 extension link, and ULA-23A coupling nut. Thread the coupling nut
onto the Viscometer coupling.
CAUTION: LEFT-HAND THREAD ON VISCOMETER AND COUPLING NUT!
3. Open Tube Operation:
The water jacket (ULA-40Y) must be removed when the open tube is used. This allows measurement
in a beaker or other container. The sample tube must be installed on the locating channel before
immersion in sample fluid.
Observe the immersion grooves located on the outside of the tube below the collar (Figure 3). The top
groove is used with YULA-15 (#304 s/s) and YULA-15Z (#316 s/s) spindles. Be sure to immerse the tube
to the proper groove in order to obtain the correct spindle immersion depth.

4. Closed Tube Operation with Water Jacket:
The UL Adapter may be used with the ULA-40Y water jacket and a circulating water bath by connecting
the water jacket to the bath inlet and outlet ports (Figure 4). The tube end cap (ULA-34) is snapped over
the end of the tube before the sample is added. Be sure that it is securely seated in the groove. Fill with
16 mL of sample fluid before installing on locating channel.
CAUTION: (1) The spindle, tube, and cap (if used) should be clean before use. The cap material is low
density polyethylene. Replace when damaged or loose.
(2)When inserting the sample tube into the ULA-40Y Water Jacket, use gentle force to
prevent damage to O-rings and collar on inside diameter of ULA-40Y Water Jacket.
5. The closed tube system with 316 s/s wetted parts may also be used without the ULA-40Y water jacket by
immersing directly into the water bath.
