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
