  • Patent number: 8318108
    Abstract: This invention relates to plunger operated liquid dispensers, such as hand held pipettors, which are used to portion liquids. Specifically the invention relates to a reliable removal of a liquid from the liquid dispenser. According to the invention the plunger of the liquid dispenser is arranged into a speeded up movement while removing the liquid. This change in speed is preferably sudden.

  • Patent number: 8304231
    Abstract: The invention relates to a bioreactor, comprising a reactor vessel (2) with a housing support (20,20a), extending into the vessel interior (14), with a medium seal against the vessel interior (14) with a transparent sensor piece (34,34a) and an indicator tile (38,38a), arranged in the vessel interior (14), in contact with the vessel contents, which may be scanned by a fiber optic which may itself be introduced into the housing support (20,20a) and connected to a display device (24). In order that the reactor may be embodied as a bag, the housing support (20,20a) is arranged on the upper side of the reactor bag and provided with a flange piece (26) tightly sealed to the vessel wall (28). The flange piece is connected to the sensor piece (34,34a) by means of a preferably tubular connector piece (32,23a), whereby the length of the connector piece is such that the sensor piece (34,34a) permanently reaches into the reactant.

  • Publication number: 20120267518
    Abstract: A sensor protector is intended to reduce the sensitivity of the optical sensor (4) to radiation products which, for example, are formed during sterilization with gamma radiation and to ensure simple and cost-effective manufacture. The sensor protector includes an upper part (1), a lower part (3) and an optical sensor (4). The optical sensor (4) situated on the lower part is positionable in an offset manner with respect to an opening (2) situated in the upper part and movable by means of displacement toward the opening (2) of the upper part (1). The sensor protector is suitable for use in containers and laboratory products that are sterilized by gamma radiation, for example disposable bioreactors.

  • Patent number: 8279428
    Abstract: A weighing scale, e.g. a top-pan scale, having a scale pan (01, 02) supported on a force transducer, and a corner load sensor (03, 04, 06, 08, 09) measuring the tilting of the scale pan (01, 02) relative to the force transducer. The corner load sensor includes a light beam source (03, 04, 06) emitting a first light beam and a second light beam. The first light beam and the second light beam are directed toward a reflecting surface on an underside of an arrangement that includes the scale pan (01, 02). The first light beam and the second light beam are respectively inclined relative to the reflecting surface of the untilted scale pan (01). The corner load sensor (03, 04, 06, 08, 09) of the scale also includes a first optical sensor (08) measuring the first light beam reflected by the reflecting surface. If no corner load exists, a predetermined proportion (12) of the reflected first light beam is directed to the first optical sensor (08).

  • Patent number: 8268059
    Abstract: The invention relates to a waste gas system for bioreactors having a hydrophobic sterile filter, arranged at the end, and a heat exchanger which protects the sterile filter against blocking by liquid media. The gas outflow duct for discharging waste gas from a bioreactor vessel is divided in a cooling zone of the heat exchanger into a multiplicity of subducts and is extended in a heating zone of the heat exchanger to a calming zone. Due to the multiplicity of subducts, a considerably larger surface area for the removal of heat from the waste gas is available, with the result that in the case of laminar flow of the waste gas through the subducts a high effectiveness of the separation of liquids from the waste gas can be achieved.

  • Patent number: 8252582
    Abstract: The invention relates to a disposable bioreactor comprising a reversible, externally attachable sensor arrangement for measuring a physical variable of a contained medium. A sensor adapter (28) for receiving an electronic sensor arrangement (34, 38; 42; 44a, 44b, 46, 48) interacting with the medium cross-flowing the peripheral lines (14, 16, 18), by means of an inner delimiting surface (32a, 32b; 42; 44a, 44b, 46, 48) of the sensor adapter, is integrated into at least one of the peripheral lines (14, 16, 18) of the bioreactor which is used to supply or discharge the medium. Said sensor adapter (28) is mounted on the peripheral line (14, 16, 18) as an insert extending the peripheral line (14, 16, 18) and which can be cross-flown by the contained medium.
