  • Planar sampler for a liquid volatile material and method
    Patent number: 5439172
    Abstract: A sampler is shown for a volatile fluid material. The fluid material is applied to a face of a base layer. A cover layer is applied directly over the face without an intermediate layer. A peripheral seal is formed between the base and cover layers. The seal is separable by a user to expose the face of the base layer directly to the atmosphere to allow the fluid volatile material to be released. The cover layer can be replaced to prevent further release of the volatile material. A method is also shown for making the sampler.
