Long brush barrel
The copper brush with extended adapter is used for manual cleaning of thick residues and burns in the barrel of a melt flow indexer or rheometer. Due to the softness of the material, you do not have to worry about damaging the instrument barrel. Thanks to the extended length, it lasts longer and removes more dirt per cleaning than standard brushes. It is mainly ideal for materials such as PET/PET/PC and additives that cause burns due to residual moisture, for example, and is very difficult to clean with cotton patches .
