AMETEK SSA- M86-090-P Small Sample Adapter Instructions

AMETEK SSA- M86-090-P Small Sample Adapter

These instructions apply to both the Standard Coupling Nut and Magnetic Coupling for Spindle Connection. This instruction sheet applies to the Small Sample Adapter with stainless steel chamber (with black water jacket) as Small Sample Adapter with Magnetic Systemwell as disposable sample chamber (with gray water jacket) that will be used with either the Standard spindle coupling nut or the Magnetic spindle coupling system. 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 the operating instructions that came with the laboratory stand.
2. Attach the locating channel (alignment bracket) to the viscometer (refer to illustration on pages 2 and 3) by threading the mounting screw into the tapped hole in the Viscometer pivot cup. Do not overtighten. Note the position of the locating pin.
3. Connect a length of 1/4 or 5/16 inch inside-diameter hose from the circulating bath outlet 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 flow to 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 to the locating channel with the mounting screw. Do not overtighten. The top plate of the water jacket should contact the locating pin when ready to begin viscosity testing.
5. Load the removable sample chamber with the specified amount of sample fluid (refer to 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. The sample fluid must be bubble-free to ensure an accurate reading.
6. Stainless Steel Sample Chambers: Carefully guide the sample chamber into the water jacket from the bottom until it contacts the metal pin in the jacket top plate. Rotate the chamber until the pin engages the slot in the side of the chamber. Raise the chamber and rotate counterclockwise (as viewed from the top) until it stops. Release the chamber, allowing it to drop and lock into place. Attach the connector cable from the viscometer head to the chamber, if there is an embedded temperature probe in the chamber.
7. Assemble the spindle, extension link and Coupling Adapter. Slowly lower the spindle into the sample fluid. Attach the Coupling Adapter to the viscometer. Position the insulating cap on the sample chamber, if desired.
8. Level the Viscometer. General operating procedures and spindle entry codes are described in the Viscometers’ 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.

Small Sample Adapter with Magnetic System

M = 1 million K = 1 thousand N = RPM e.g. Spindle SC4-18 1.32 x 10 (RPM) = 13.2 sec-1 cP = Centi poise mPa•s = Millipascal-seconds
N/A = Not applicable for historical reasons. However, it is possible to use any spindle/chamber combination with any torque range. Digital viscometers/rheometers will
automatically calculate the viscosity

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.

Table 4
DIN* Spindle Ranges for Small Sample Adapter.

DIN spindles conform to DIN 53019. The 82 spindle (SC4-DIN-82) works in an SC4-13R or SC4-13RP chamber. The 83 spindle (SC4-DIN-83) works in an SC4-7R or SC4-7RP chamber.
