Dounce / DUALL®
DUALL® with All-Glass Combines both conical and cylindrical surfaces to effectively reduce tissue and produce a uniform homogenate. Grinding efficiency is greatly improved when this tube is used.
Dounce All-Glass Tissue Grinders Designed primarily for cellular work where the nucleus remains intact after homogenization.
• • •
All-glass construction
• This ground glass model is ideal for connective tissue such as muscle, heart and lung • Construction is strong enough to allow the pestle to be motor-driven • Pestles are designed to be used with 788000 stirrer adapters • Replacement components are available and completely interchangeable • Clearance between pestles and tubes is 0.004” to 0.006” • Manufactured from 33 expansion, low extractable borosilicate glass conforming to USP Type I and ASTM E438, Type I, Class A requirements
Two pestles are supplied with each complete unit Large clearance pestle is used for the initial sample reduction
• Small clearance pestle is used to form the final homogenate • Replacement components are available and completely interchangeable • Manufactured from 33 expansion, low extractable borosilicate glass conforming to USP Type I and ASTM E438, Type I, Class A requirements
