Abstract
A coating formulation for making a porous coating on a laboratory apparatus is provided. The formulation comprises 100 parts by weight hardenable resinous material, and from about 0.1 to about 50 parts by weight blowing agent based on the 100 parts by weight resinous material. The resinous material has a hardening time which is sufficiently short such that gas generated by the blowing agent is entrapped within the resinous material. The coating formulation is hardenable upon application to a surface of a laboratory apparatus to form a porous coating which is used for marking purposes or for the retention of biological samples. Methods of retaining a biological sample on a coated laboratory apparatus are also provided.
