<p>Materials for media consisting of a fiber layer, a polymer layer (A) free from any color former or selecting agent and another polymer layer (B) containing a color former and/or a selecting agent which are layered on each other in this order. The use of these materials makes it possible to accurately and quickly effect microbial examinations on subjects having curved or somewhat uneven surfaces. Moreover, these materials take up only a small space and cause little waste after using.</p> |
