    Abstract: An aperture module for obtaining signals from microscopic particles suspended in a sample blood solution which passes through a scanning aperture. A module housing including an aperture holder is mounted on a container or bath containing a body of the particulate liquid suspension to be tested. The aperture holder with aperture formed therein extends into the vessel to permit passage of the sample through the aperture to an outlet chamber immediately behind the aperture. The chamber is connected to a source of clean electrolyte and has a narrowed or reduced dimension portion positioned immediately behind the aperture. A vacuum is applied to the chamber to cause the sample to be drawn through the aperture for testing thereof. An optical hemoglobinometer is positioned in association with the bath to measure the hemoglobin content of the solution to be tested.

    Abstract: A fluid transfer mechanism (10) for rapidly and accurately picking up or aspirating a fluid quantity or aliquot in one position, moving it to a second position and dispensing the aspirated aliquot. The mechanism can include an arm mounted at one of its ends on a high helix shaft (28) and driven up and down the shaft by a first motor (40) and rotated around the shaft by a second motor (38). The arm includes at its other end a fluid transfer probe (24) which is moved into and out of the fluids to aspirate and dispense the fluids in precise angular locations. The arm may be accelerated and deaccelerated as it is rotated to avoid vibrations and spilling of the fluid from the probe. The probe may include a level sensing structure for sensing when the probe has contacted a fluid surface. The probe can be coupled to an oscillator means (30) to oscillate the probe in a vessel into which the fluid has been dispensed to mix the fluids therein.
