A modified semi-automated technique for \+i\in vitro\-i\ assessment of encrustation of materials

The method described comprises a circular reaction chamber with an encrustation mixture, the level of which is controlled by a float switch which operates the exit peristaltic pump. The composition of the reactants used simulates infected urine with alkaline pH. Results of a preliminary study of the...

Description
Summary:The method described comprises a circular reaction chamber with an encrustation mixture, the level of which is controlled by a float switch which operates the exit peristaltic pump. The composition of the reactants used simulates infected urine with alkaline pH. Results of a preliminary study of the deposits by scanning electron micrography and energy dispersive X-ray microanalysis are consistent with struvite and hydroxyapatite, similar to the main mineral deposited on urinary catheters.
