ABSTRACT:
An improved biological test apparatus has an organoplastic support surface which has been treated to become hydrophilic, said surface supporting an aqueous gel employed for the desired test mechanism. The hydrophilic treatment enables the aqueous gel to be in uniform close adherent contact with the support surface. This prevents the formation of an uneven gel thickness and improves the adherence of the gel to the support surface during storage and subsequent use.
