Is it good to use detergent solution or warm water for washing the stylus tube?

For customers using samples that leave a residue in the sample tube we would recommend that the stylus is regularly flushed through with a hot detergent solution i.e. detergent at 50° – 55° and 1% detergent. With WASP set in valve mode draw the detergent solution into the instrument as though it were a normal sample. If you have a large build up it may be necessary to push the solution through the stylus using the “back flush” system and a 50 ml syringe. This requires removing the cover of the instrument, rather than using the ‘power wash’ or ‘sample return’ functions.
