Chemotechnique Diagnostics is pleased to offer the most advanced patch testing chambers unit. New advantages-making patch testing easier, and more convenient for both the practitioner and the patients. 

​

The IQ Ultra® patch test unit has important advances:

Each chamber has a filter paper incorporated which eliminates adding loose filter papers.

The rim of each chamber has an adhesive layer to optimize adhesion to the skin and to eliminate leakage. This makes IQ Ultra® a closedcell 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 thus making them even more comfortable for the patients.

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 correspon-ding compartments which makes it possible to re-attach the tape after advance filling of the chambers with the allergens.

The IQ Ultra® Application device 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.

IQ Ultra® is made of additive-free polye-thylene plastic foam with a filterpaper incorporated.

IQ Ultra® is supplied in units of 10 chambers

(in 2 rows of 5 chambers/row) on a hypo-allergenic non woven adhesive tape.

The tape with the chambers has a protective plastic cover with 10 corresponding comp-artments. The cover makes it possible to re-attach the tape to the cover after advance filling of the chambers with allergens.

The volume of the chamber is 34 µl and the inside area of the chamber is 68mm2.

The width of the tape is 52mm and the length is 118mm.

The IQ Ultra® is supplied in cardboard boxes containing 100 units per box (100x10 chambers).

The IQ Ultra® is available worldwide through the extensive network of Chemo-technique Diagnostics distributors.

The basic requirements for a patch test chamber involves using an inert material applied to a hypoallergenic tape providing good occlusion and fixation of the test unit to

the skin.

The material of the IQ Ultra® is inert, additive free polyethylene foam and the opening of the chamber is square to make it easier to differentiate between allergic and irritant reactions. Undesired side effects in the form of allergic reactions to the test unit itself (1-24) are avoided due to the chemical stability of the polyethylene plastic. The effect of reactive test substances on the test cham-ber which may result in secondary toxic reac-tions during the patch test (25-30, 33), is also avoided due to polyethylene’s chemical resi-stance to these types of substances. By using inert plasticmaterial such as polyethylene, the risk of inactivation, modification and absorp-tion of the hapten during contact with the surface of the test chamber is avoided (31-32, 35). Considering these facts, the impor-tance and advantages of using chambers made of inert plastic material has been demonstrated (33-34, 36-37).
