This instruction sheet applies to Small Sample Adapter with stainless steel chamber (with black water jacket) as well as disposable sample chamber (with gray water jacket). Spindles that can be used with the Small Sample Adapter are identified in Tables 2 and 4.
1.Mount the viscometer securely on its laboratory stand per operating instructions that came with the laboratory stand.
2.Attach the locating channel to the viscometer (refer to illustration on page 2) by threading the upper mounting screw into the tapped hole in the Viscometer pivot cup. Do not overtighten. The end of the locating channel with the pin in it must point down.
3.Connect a length of 1/4 or 5/16 inch inside diameter hose from temperature bath circulating pump (outlet) fitting to the lower (inlet) fitting on the water jacket. Connect another length of hose from the upper (outlet) fitting to the bath (inlet) fitting. Hoses should be long enough to allow proper circulation in the water jacket without exerting any “side thrust” on the assembly during operation.
Minimum temperature is 0°C and maximum temperature is 100°C; over 60°C use high temperature tubing. For tubing and fluid recommendations, see Table 1.
4.Attach the water jacket assembly to the locating channel with the lower mounting screw. Do not overtighten. The top plate of the water jacket should contact the locating pin in the locating channel. (For stainless steel chambers: the top of the water jacket may be identified by the metal pin protruding into the chamber sleeve.) Loosen the mounting screw, and slide the water jacket down to allow spindle attachment.
5.Load the removable sample chamber with the specified amount of sample fluid (see Table 2) by leaning the chamber at a 45° angle and pouring the sample fluid slowly down the inside wall of the chamber to avoid air bubble entrapment. Sample fluid must be bubble-free to ensure an accurate reading.
Note: Immersing the spindle will displace the fluid so take care not to overfill the chamber to avoid spillage of the sample fluid.
6.Stainless Steel Sample Chambers: Carefully guide sample chamber into water jacket from the bottom until it contacts the metal pin in the jacket top plate. Rotate chamber until the pin engages the slot in the side of the chamber. Raise chamber and rotate counterclockwise (as viewed from the top) until it stops. Release chamber, allowing it to drop and lock into place. Attach connector cable from viscometer head to chamber, if there is an embedded temperature probe in the chamber.
Disposable Sample Chambers (Part No. SC4-13RD-100): Carefullyguidethesamplechamberintothewaterjacketfromthebottom until it is inserted high enough to allow closing of the latch at the bottom of the water jacket. Be sure the latch closes completely, engaging the positive snap lock. Rotate the sample chamber until it drops into the locked position where the flat side of the pin at the bottom of the sample chamber engages a flat side of the latch. This prevents the chamber from turning with the spindle during sample measurements.
Note: Disposable sample chambers, available in packages of 100 chambers, are replacements for SC4-13R sample chambers only.
7.Assemble the spindle, extension link and coupling nut. Slowly lower spindle into sample fluid. Thread coupling nut (please note thread is left handed) ont viscometer spindle coupling. Position insulating cap on sample chamber if desired.
Note: 1. Spindles SC4-14, 15, 16, 21, 25, 27 and 29 have solid shafts and do not require a coupling nut or link.
2.Optional #316 stainless steel spindles and chambers are available for acidic or corrosive samples. Contact Brookfield
Engineering or your local authorized dealer.
3.Disposable spindle SC4-27D can be used with Alignment Bracket SC4-46DY and Chuck Closer SC4-DSY.
8.Level the Viscometer. General operating procedures and spindle entry codes are described in the Viscometer instruction manual.
9.Spindle factors for the Small Sample Adapter are shown in Table 3. The spindle factor enables the operator using a Dial Reading Viscometer to convert the torque reading to a viscosity reading in centipoise. The spindle factor, when multiplied by 100, defines the maximum viscosity in cP that can be measured.
10.Clean the spindle and chamber using appropriate cleaning solutions.
Note: The black insulating bottom of the sample chamber should not be exposed to strong solvents such as methanol, toluene, ammonia and 111 trichloroethylene. Do not totally immerse the chamber in any cleaning solution. Improper cleaning may result in separation of the black insulation from the chamber.
