The patented Inert Quadrate design
Features & Benefits
The IQ Ultra™ patch test unit has important advances:

  • Each chamber has a filter paper incorporated which eliminates adding loose filter papers to facilitate handling of liquid haptens.
  • The rim of each chamber has an adhesive layer to optimize adhesion to the skin and to eliminate leakage. This makes IQ Ultra™ a closed-cell system enhancing occlusion and confining the test reaction within the chamber parameter.
  • The size of the IQ Ultra™ is small to allow the application of multiple test units to patients’ backs.
  • The chambers are made of thin and soft polyethylene foam material to maximize patient comfort.
  • The highest quality hypoallergenic surgical tape is used for the IQ Ultra™. Each strip of 10 chambers of IQ Ultra™ is attached to a protective plastic cover with corresponding compartments which makes it possible to re-attach the tape after advance filling of the chambers with the haptens.
  • The Application device for IQ Ultra™ makes advance filling of test substances even easier. The device is specifically designed for the IQ Ultra™. It is cost effective and saves nurses/technicians time, as they can prepare test series up to two weeks prior to use. Volatile haptens such as acrylates and fragrances should not be preloaded.
