Latest Patents

Holubar's most notable invention is the Automatic Closed Tube Sampler. This sophisticated apparatus is designed for transporting racks of sealed sample tubes, mixing sample materials contained within the tubes, and aspirating samples efficiently. The device features a car that moves along a rail to drive racks holding the sample tubes into a mixer channel, which is oriented above and parallel to the rail. The mixer channel rotates around an axis that is also parallel to the rail, facilitating the mixing of samples and the positioning of tubes for aspiration.

A push pin located near the mixer channel extends into it, urging individual tubes against an aspirator assembly on the opposite side. The apparatus includes an input queue on the input side of the rail and an output queue on the output side. The input queue supports racks and loads them onto the car mechanism, while the output queue receives racks post-aspiration and feeds them out, thereby making room for new racks.

The innovative design incorporates a structured rack with a lateral front wall, lateral rear wall, and a horizontal bottom wall, defining various tube receptacles outfitted with apertures for the push pin access. Ribs are included in the bottom wall to ensure the car's engagement, and biasing means are present within each receptacle to support the sample tubes securely.
