Finn Chamber^® is a patch test device which provides good occlusion because of the chamber design. The 8 mm inner diameter provides a 50 mm² area and about 20 µl volume. Finn Chambers are available mounted on Scanpor® tape, Actavis Norway AS, Norgesplaster, with protective paper backing which is easily peeled away. The chambers are made of aluminium. Polypropylene coated chambers (8, 12, 18 mm) and 12 mm aluminium chambers are available for special purposes.

Finn Chambers on Scanpor are available in strips of 10 (2x5), 5 (1x5) and 1 chambers. The strips of 10 chambers are practical when testing with a large number of substances, e.g. with routine tests. Smaller strips are suitable for small test series and individual tests.

Most commercial test substances are suitable for Finn Chambers. The substances incorporated in a semisolid base are applied directly into the chamber. For liquids a filter paper disc is placed in the chamber and saturated with the liquid.

Finn Chamber Tray keeps the test strips in good order when applying the test substances. The trays can be piled on each other, which saves place on the desk.

The tests are applied preferably on the upper back. When removing the tests after one or two days' exposure the occlusion is verified by a ring-shaped depression around each test.

For locating the test sites a special device, Reading Plate, is recommended. Reading Plate can also be used when removing the tests.

Testing with Finn Chambers is

Reliable

• tight occlusion due to the special design of the chamber
• the validity of occlusion is indicated by a ring-shaped depression around the individual test sites at the time of removal
• good fixing of the tests onto the skin since the size of the chamber is small relative to the adhesive tape

Kind to the skin

• small reactions due to the small size of the chamber save the patient from unnecessary discomfort
• minimal skin irritation and sweat retention because of the use of the porous tape
• sensitivity reactions to aluminium and Scanpor are rare

Economical

• the method is convenient and time saving
• due to the small testing area, a large number of test substances can be applied at one time
• only small amounts of test substances are required
