System Design/ Options

The basic component of the Hill Top Chamber System is a molded plastic chamber flexible enough to conform to the contour of the skin. This chamber has a unique double rim, consisting of an outer ring and an inner flexible flange, for a close fit to the skin surface to increase occlusivity. Within the chamber a non-woven Webril© pad holds the test sample. The chamber is sandwiched between squares of release paper and semi-occlusive, hypoallergenic adhesive tape, ready for use. The Hill Top Chamber can be provided in single-unit form or in multi-unit strips with any number of chambers. Virtually any size or shape of chamber can be custom produced.

Plastic chambers alone, with or without Webril© pad are also available.

Chamber Composition

The Hill Top Chamber is manufactured using Kraton® G-2705, a product of the Shell Oil Company. Kraton® meets or exceeds the current USP requirements for physico-chemical and biological tests for Class VI polymers. The chamber is soft and flexible thus providing cohesion between the test material and the skin sites. The Kraton® material has been approved for use by the FDA. Other plastics may be provided based on client need. Hill Top Chamber Systems are backed with Durapore®, a "silk-like" tape with a latex-free, hypoallergenic adhesive manufactured by 3M that offers high strength and adhesion. Webril® inserts are 100% cotton.
