ISO9001 CERTIFIED
The UL Adapter is a kit consisting of a spindle, a sample tube, mounting channel, water jacket, coupling nut,
extension link and six end caps. It is available in two versions: (1) with type 304 s/s wetted parts as pictured
in Figure 1; (2) with 316 s/s wetted parts as pictured in Figure 2. All versions are shipped with the water jacket
(ULA-40Y) mounted on the sample tube.
The type 304 s/s* UL Adapter may be used as an “open tube” or “closed tube” system. In the “open tube”
method, the water jacket (ULA-40Y) must be removed, allowing measurement in a beaker or other suitable
vessel. In the “closed tube” method, the sample is poured into the sample tube. The closed tube may be
temperature controlled with the use of the water jacket.
The 316 s/s** UL Adapter is available only in the “closed tube” system. The closed tube system may be
temperature controlled with the use of the water jacket or the sample tube may be immersed into a temperature
bath.

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.
