A multi-slot die coater may improve a problem that is structurally vulnerable to deformation and torsion. The multi-slot die coater including a lower slot and an upper slot includes a lower die block; an intermediate die block disposed on the lower die block to form the lower slot therebetween; and an upper die block disposed on the intermediate die block to form the upper slot therebetween, wherein at least one of the lower die block, the intermediate die block, and the upper die block comprises a metal coating layer on a ceramic body.

Disclosed is a dual slot die coater capable of discharging a coating solution through an outlet after removing air bubbles contained in the coating solution. The dual slot die coater according to the present disclosure includes a first air vent installed in the first manifold region and an uppersecond air vent installed in the second manifold region.

There is provided a dual slot die coater that is easy to adjust a coating gap and can control a widthwise deviation of coating gap. The dual slot die coater of the present disclosure includes a plate member including a lower plate, an intermediate plate positioned on the lower plate and an upper plate positioned on the intermediate plate, wherein a lower slot is formed between the intermediate plate and the lower plate, and an upper slot is formed between the upper plate and the intermediate plate; a block provided on a rear surface of the plate member, wherein the block can be separated from or coupled to the plate member, or integrally formed with at least one plate of the plate member; a first bolt to push at least one plate of the plate member from the block as the first bolt passes through the block; and a second bolt to pull the at least one plate of the plate member toward the block as the second bolt passes through the block.

An apparatus and method for producing a coated analytic substrate using a compact and portable automated instrument located in the laboratory setting at the point of use which can consistently produce one or a plurality of coated analytic substrates “on demand” for using the analytic substrate immediately after coating, preferably without a step of rinsing the coated analytic substrate before use. The apparatus preferably uses applicator cartridges having a reservoir containing the coating compositions used to form the coatings. Preferably the cartridges are removable and interchangeable to facilitate the production of individual analytic substrates having different coatings or different coating patterns. These coated analytic substrates have superior specimen adhesion characteristics due to the improved quality of the coatings applied by the coating apparatus and due to the quickness with which the coated analytic substrates can be used in the lab after production.

An applicator head for a vacuum coating system includes a manifold shell having opposing shell plates, each including a conduit attachment coupled to a shell aperture. An applicator manifold is affixed to each shell plate. Each applicator manifold includes two coupled manifold plates, with one including a manifold aperture, and each is affixed to the respective shell plate so that each manifold aperture aligns with the respective shell aperture. An applicator channel is formed between the manifold plates of each applicator manifold, and the applicator channel is fluidically coupled to the manifold aperture of each respective applicator manifold. Each applicator channel forms an applicator port at a leading edge of each respective applicator manifold, and each leading edge is configured to be complementary in shape to an edge of a workpiece to be coated. First and second face plates are disposed over the leading edges of the applicator manifolds.
