seen to take and extracting the specimen, serskilt for scientific or diagnostic undersokningar, and device for this sampling

摘要

A method for taking and collecting sample material. A sampler is used which consists entirely, or at least at its surface or contact area, of a plastic material which is soluble in water. The sampler, after wetting and hence superficial dissolution, is brought into contact with the surface to be examined. The sample material sticks to the plastic. The sampler is removed and dissolved, whereby the sample material is collected.
