Magnaflux 2461 Product Data Sheet

GENERAL DESCRIPTION
Magnaflux ® Centrifuge Tubes are used to monitor the concentration of magnetic particles and the level of
contamination in Magnaglo
BATH STRENGTH
The amount of magnetic particles per gallon of fluid in the inspection bath is called its strength or
concentration. If the bath concentration is below recommended strength, weak particle indications will be
produced or possibly no indication will appear; therefore, defects will not be detected. If there are too many
particles in the bath, indications may be masked by heavy background buildup. The usable limits of bath
strength are quite broad, but for consistent results the bath strength should be maintained constant at all
times.
A light bath strength usually forms good indications on deep cracks, but a heavier particle concentration will
show fine defects better. The bath concentration, which will best detect all defects, should be determined and
held constant. Bath strength should be checked at least once each day.
After the entire bath has been thoroughly mixed and agitated, it is essential to check it for strength. The most
widely used method is by gravity settling in a graduated ASTM pear shaped centrifuge tube.
