Test Devices
Standard Finn Chambers; round aluminum
disks 8 mm diameter on Scanpor tape (Finn Chamber ,
Epitest Ltd., Finland) usually used for epicutaneous
testing were used. A webril cotton size 1 cm x 1 cm was
placed on to each aluminum disk and saturated with a
sufficient amount of the test material to cover the surface
of the pad. The patches were secured in place to
the upper outer arms with non-allergic porous, surgical
tape (Micropore , 3M)
