In response to such testing, server usage is selectively adjusted, as necessary, to ensure that the user is provided with effectively uninterrupted service, and so that the service provider may be immediately alerted to error conditions. 5 is formed of the colorant, and a background 6 is formed with the metachromatic ink. This is achieved by virtue of the arrangement, where on at least one of the sides of the plates pointing toward one another in the sealing region, there is a projection which, when forced by pressure onto the sealing plate, brings about a deformation of the seal in the direction of the inner wall of the tube or tubular vessel. In particular, a sample plate used to concentrate a sample as well as remove contaminants from the sample while providing easy manipulation of small liquid droplets on a surface with minimal sample loss. A cured product obtained by curing this composition is transparent, displays good strength and particularly good flexural strength, and moreover also displays a high degree of hardness.
