Combines both conical and cylindrical surfaces to effectively reduce tissue and produce a uniform homogenate. Homogenising efficiency is greatly improved when this tube is used. - Construction is strong enough to allow the pestle to be motor driven. - Clearance between pestle and tube is 0.1 to 0.15 mm. - Replacement components are available and completely interchangeable. Homogenisers, DUALL® with glass pestle: ideal for connective tissue such as muscle, heart and lung. Homogenisers, DUALL® with PTFE pestle: ideal for soft tissue as brain or liver.
