Abstract
An improved capillary rheometer features a barrel surrounded by electrical heating elements which are automatically controlled to maintain constant temperature along the barrel length, a liner for the barrel to hold a sample, a capillary tube retained in a holder that fits in sealing relation with the liner; and a bottom plate which prevents displacement of the capillary tube. The assembly of liner, capillary and holder is easily removed and replaced to provide for quick sample changes and easy cleaning.
