QLA offers numerous industry standard devices for Transdermal testing

For USP APP 5, both Hanson-style and VanKel-style patch retainers are compatible with all brands of dissolution baths. The transdermal patch is placed either between a glass disk and an inert mesh screen, or directly onto a stainless-steel mesh assembly. It is placed at the bottom of the vessel, with the release side facing upwards, under a rotating paddle.

For USP APP 6, the transdermal patch is attached to the outside surface of the cylinder. QLA's Rotating Cylinders and Extensions are serialized and come with a Certificate of Conformance. If an extension is needed, it should be ordered at the same time as the main cylinder. Other shaft lengths are available upon request.

The testing is carried out at 32°C to reflect the temperature of the skin.
