ABSTRACT:
A capillary rheometer plunger having a liquid-filled capillary passage extending within the plunger is removably housed in a heater block holder for maintaining temperature stability and minimizing temperature induced errors. The plunger is placed in the holder during purging, cleaning, reloading and packing the capillary rheometer with the polymer under test. The holder includes an electrically heated holder member disposed within an aperture of an outer shield and is provided with an aperture in which the plunger is removably received for heating. A base supports the shell. A temperature sensor disposed in the shell controls the temperature of the holder member at the temperature of the polymer under test.
