Assembly & Operating Instructions
No. M06-084
The Enhanced UL Adapter, shown in Figure 1, is a kit consisting of a spindle with coupling nut attached, sample
chamber, mounting channel, and water jacket with mounting collar. It is available in two versions: (1) with type
304 stainless steel suitable for most general purpose applications; (2) with type 316 stainless steel for use with
corrosive/acidic applications. All versions are shipped with the water jacket (ULA-49EAY) mounted on the
sample chamber.
The type 304 s/s UL Adapter (Part No. ULA-EY) may be used either as an “open tube” or “closed tube” system.
In the “open tube” method, the water jacket (ULA-49EAY) must be removed, allowing measurement in a beaker
or other suitable vessel. In the “closed tube” method, the sample is poured into the sample chamber with tube end
cap installed, which may be temperature controlled by direct immersion into a water bath or with the use of the
water jacket connected to a circulating water bath. The 316 s/s UL Adapter (Part No. ULA-EZY) has a closed
sample chamber with solid bottom and cannot be used as an open tube conguration.
The Enhanced UL Adapter may be ordered without the water jacket (Part No ULA-E). Check your sales order to
verify that you have received the correct conguration for your Enhanced UL Adapter.

IMMERSION GROOVE
END CAP GROOVE
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 uid. The top of the sample chamber should be ush 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 uid. 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. Conrm that the uid 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
