Try the laboratory supply houses like VWR Scientific Products
(1-800-932-5000), or JT Baker(1-800-JTBAKER) for "Baker Test Strips" They
have a lot of different specific ion test strips.

> had issues with cross contamination of water soluble and no clean flux due

> Anybody have any ideas on how to prevent cross contamination of fluxes
