<p>REHYDRATOR The rehydrator is comprised of a first plate having a plurality of hollow tubes secured in through apertures and extending from one side of the plate perpendicular thereto. A plurality of rods are secured to a second plate disposed parallel to the first plate and extend through respective tubes in the first plate. The second plate is guided for movement toward and away from the first plate on a plurality of guide rods and springs are provided to normally bias the second plate away from the first plate. The rods slide loosely within the tubes and upon movement of the second plate downwardly into engagement with the first plate, the ends of the rods will extend beyond the tubes so that upon immersion of the ends of the rods and tubes into a solution, the withdrawal of the rods into the tubes will cause a predetermined amount of fluid to be drawn into the tube. Subsequent extension of the rods past the ends of the tubes will cause the liquid therein to be dispensed into appropriate receptacles aligned with each tube.</p> |
