Brookfield UL Adapter, Enhanced - Manual (Page 2)

Brookfield Engineering Laboratories Inc. - - Operating Instructions M06-084-A0507
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.
2. Open Tube Operation (#304 stainless steel)
The water jacket (ULA-49EAY) must be removed when the “open tube” method is used. This allows
measurement in a beaker or other container. The sample chamber must be inserted into the clamping collar
before immersion in sample fluid. The top of the sample chamber should be flush with the top edge of the
clamping collar.
The clamping collar connects to the mounting channel as shown in Figure 1. The spindle with coupling nut
can be attached to the viscometer beforehand for easy handling. Observe the immersion groove located on
the outside of the sample chamber as shown in Figure 2.
3. Closed Tube Operation with Water Jacket
The UL Adapter may be used with the ULA-49EAY water jacket and a circulating water bath by connecting
the water jacket to the bath inlet and outlet ports (Figure 3). The tube end cap (ULA-34) is snapped over
the bottom end of the sample chamber before the sample is added. Be sure that it is securely seated in the
groove. Fill with 16 mL of sample fluid. Insert the clamping collar into the mounting collar as shown in
Figure 1. Insert the sample chamber upwards into the water jacket and clamping collar. When fully inserted,
secure the sample chamber by tightening the clamping knob. Insert the spindle into the chamber. Attach the
clamping collar to the mounting channel. Connect the spindle coupling to the viscometer; note left hand
thread. Confirm that the fluid level in the sample chamber covers the conical portion of the spindle shaft.
CAUTION: The spindle, sample chamber, and cap (if used) should be clean before use. The cap material
is low density polyethylene. Replace when damaged or loose.
