    Abstract: A sample holder and shutter assembly for photometers is disclosed in which a stationary sample chamber body is mounted in close proximity to a photosensitive device. A light path is provided from the sample chamber to the photosensitive device and shutter means is provided for selectively interrupting and opening the light path between the photosensitive device and the sample chamber without moving the sample chamber. Heat exchange means including a heat pump and a heat reservoir are provided for maintaining a desired temperature in the sample chamber. The sample chamber body is thermally connected to said heat pump and is preferably thermally isolated from the means mounting it. In one embodiment, the heat pump and heat reservoir are flexibly connected.

    Abstract: OBJECT PROCESSING DEVICE A device for handling and washing beads. The device is attachable to a test tube rack and includes a frame, a containing slide, and a capture slide. By manipulating the slides in various combinations of positions the beads may be added to, removed from, or separately washed apart from test tubes in the rackc. Complete and easy washing of the beads may thus be accomplished.

    Abstract: 420D-165 Canada METHOD AND APPARATUS FOR MONITORING LIGHT SIGNALS FROM LIQUID MEDIUM In processes for detection and measuring a substance or condition in a fluid medium by the effect of the substance or condition on a light emitting substance, such as luminous microorganisms, disposed in the medium, a method and apparatus is provided for determining the effect of the medium on the light signal due to the medium absorbancy or other factor which is independent of the effect of the substance or condition on the light emitting substance. This is accomplished by deriving from the transmittance of the fluid medium using an external light source the expected transmittance of the fluid medium containing the light emitting substance according to the expression where A is the absorbancy of the fluid, c is the concentration of the absorbing substance and D is the mean absorbtion path length of the photons emitted. The expected transmittancy is applied to the observed transmittancy of the test sample to obtain the transmittancy of the test sample independently of the optical effects of the medium. A cell design is disclosed for determining the absorbancy of the fluid medium using a single instrument.

    Abstract: Un assemblage de support d'echantillons et d'obturateurs (20) pour photometre comprend un corps de chambre d'echantillon nage fixe (40) monte a proximite d'un dispositif photosensible (18). Un passage lumineux est prevu de la chambre d'echantillonnage (53) au dispositif photosensible (18) et un obturateur est prevu pour fermer et ouvrir de maniere selective le trajet de la lumiere entre le dispositif photosensible (18) et la chambre d'echantillonnage (53) sans deplacer celle-ci. Des moyens d'echange de chaleur comprenant une pompe de chaleur (63) et un reservoir de chaleur (68) sont prevus pour maintenir la temperature desiree dans la chambre (53). Le corps de la chambre d'echantillonnage (40) est relie thermiquement a la pompe de chaleur (63) et est de preference isole thermiquement des moyens ou il est monte. Dans une realisation, la pompe de chaleur (63) et le reservoir de chaleur (68) sont relies de maniere souple.
