System Description
The Gardner-scrub Abrasion Tester helps evaluate washability and abrasion resistance of a
material. The tester reciprocates an abrasive device linearly over a sample. The abrasion
device can be a brush, sponge, abrasive pads and other abraders. The traversing carriage is
designed to hold 1, 2 or 3 abrading devices depending on their size.
Two sample clamps slide on shafts at the rear of the instrument to allow various sized
samples to be held in place during testing. The clamps will also hold Lilly Frames or other
accessories in place.
