A device for applying at least one coating material to a substrate surface. The device includes a flexible base plate having a toothing which is mounted on at least one side of the flexible base plate as a toothed side, a channel which is arranged parallel to the toothed side, and at least one sealing lip which is arranged on a side of the channel which faces away from the toothed side.

The present invention is directed toward an apparatus for producing consistent blood and bone marrow smears. The apparatus may include a smearer configured to receive a planar smear slide. The smearer may include an angled portion that comes into contact with the planar smear slide and creates the smear. The apparatus operates by allowing users of all skill levels to prepare a blood or bone marrow smear sample.

A powder coating device including: a powder feeder that feeds powder onto a surface of a base material; a squeegee that is disposed to form a gap with respect to the base material and has a surface in contact with the powder fed onto the surface of the base material, the squeegee being configured to adjust a thickness of a powder layer composed of the powder fed onto the surface of the base material by the powder feeder and move relative to the base material in a state where an inclination angle of the surface of the squeegee with respect to a normal direction of the surface of the base material is changeable; a powder inclination angle detector that detects an angle between a surface of the powder layer and the base material; anda first controller that adjusts the inclination angle of the surface of the squeegee in contact with the powder based on the inclination angle of the powder layer detected by the powder inclination angle detector.
