  • Patent number: 9964502
    Abstract: The present invention relates to a thermal conductivity detector, comprising a sensor block having two cavities for the purpose of accommodating gases, wherein one of the cavities is open and the other cavity is sealed and in each of the cavities there is disposed a thermistor and also sealing elements for the purpose of sealing the cavities, which sealing elements comprise electric current feed through elements, which are electrically connected to the respective thermistor disposed in the respective cavity. At least the sealing element in the sealed cavity is a glass to metal feed through element, which is welded to the sensor block to form a gas-tight joint.

  • Publication number: 20130052101
    Abstract: The invention relates to a laboratory climatic cabinet, in particular a gassed incubator, having an interior enclosed by a housing and the steam generator arranged outside the interior, which is connected to the interior via a steam feed line. The steam generator is designed as an essentially unpressurized container having a base area and a steam region located above it, the base area being designed to accommodate a water reservoir and being provided with a heating device for heating the water reservoir, the steam feed line leaving the steam generator in the area of the steam region and an air feed line opening into the steam generator, in order to feed ambient air to the steam generator and to introduce air enriched with water steam via the steam feed line in essentially unpressurized form into the interior of the incubator.

  • Patent number: 8211694
    Abstract: Climate control unit with an interior section containing a storage space and with a closable access opening to the storage section whereby at least one part of the interior section is separated and sealed against the rest of the interior section thus forming a separate germ-proof section. The division takes place at least in part by a membrane that is permeable for water vapor and gas but impermeable for microorganisms.

  • Publication number: 20060148094
    Abstract: For humidifying a work space in a gas-fed incubator, water in a heatable pan in the floor area of an inner container surrounding the work space is evaporated with temperature-controlled heating of the interior until a predetermined temperature is reached, whereby a dynamic equilibrium state between condensation and evaporation in the inner container is achieved as long as there are no disturbances. If a door for access to the inner container is opened, the open time until it is closed is detected and a period, during which the pan containing water is heated, is determined depending on the open time of the inner container. Here, the period features only a heating phase with a running time if the open time is within a predetermined time interval. The period further includes a secondary heating phase with a second running time if the open time exceeds the time interval.

  • Patent number: 6299837
    Abstract: A gassing incubator includes an inner housing bounding a inside space. The inside space communicates to the exterior through an opening. The opening is selectively sealed closed by a movable door. The inner housing includes a floor which is configured to receive and retain water. To disinfect the inside space, water is disposed on the floor and the opening is sealed closed. The inside space is then heated to a disinfecting temperature of about 90° C. The water is also heated so as to produce a relative humidity of greater than about 80% within the inside space. This atmosphere is maintained for a disinfection phase of at least 9 hours. The hot and humid atmosphere of the inside space produces great heat sensitization of cells which might be present. As a result, substantially all of the cells within the inside space are killed during the 9-hour disinfection phase.
