Plastic inserts, rotors

Buckets and tube cups are often improperly balanced. Take care to ensure that matched sets of buckets, adapters, and plastic inserts do not become mixed. If these components are not inscribed with their weights by the manufacturer, application of a drop of colored paint will help to identify matched sets. In balancing rotors, consider the tubes, buckets, adapters, and inserts, and any disinfectant solution or water added for balancing. Account for solution densities in the balancing proce-... 

In processing methacrylate polymer, the addihon of too low a concentration of plasticizer substantially increased power supplied to the rotor.In the opposite case of too large an amount of the plasticizer, the extrasion torque becomes too small for process requirements. In medical applicahons, a biocompatible plashcizer was used in the apparatus for vascular embolization. The catheter used in this process must be flexible for insertion but then should become rigid. This is achieved by the use of the plasticizer which is extracted by vascular blood and removed from the microcatheter. ...
