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.
Claims21
A laboratory apparatus having a porous coating formed on a surface thereof, said porous coating having a thickness of less than about 100 mils and comprising the hardened product of a coating formulation, said formulation comprising 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, said hardened product comprising hardened resinous material, gas cells at least partially entrapped within said hardened resinous material, and a porous surface.
A laboratory apparatus having a porous coating formed on a surface thereof, said porous coating having a thickness of less than about 100 mils and comprising the hardened product of a coating formulation, said formulation comprising 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, said hardened product comprising hardened resinous material, gas cells at least partially entrapped within said hardened resinous material, and a porous surface, wherein said porous coating is scratch-resistant to a #6 pencil.
A laboratory apparatus having a porous coating formed on a surface thereof, said porous coating having a thickness of less than about 100 mils and comprising the hardened product of a coating formulation, said formulation comprising 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, said hardened product comprising hardened resinous material, gas cells at least partially entrapped within said hardened resinous material, and a porous surface, wherein a biological sample is retained by said porous surface.
