  • Patent number: 7100396
    Abstract: The invention concerns a climatic cabinet, in particular, a climatic cooling cabinet, whose interior is loaded or unloaded with specimen slides, with the aid of a transporting device. The loading and unloading take place through a loading opening which can be closed with a door, which opening is adapted, in its size, to the dimensions of the specimen slides and is located in a sidewall of the climatic cabinet. The climatic cabinet also has a gas supply device, whose at least one gas exhaust opening is situated in such a way that the cross-section of the loading opening is covered by a gas curtain, in the area of the gas exhaust openings when gas is supplied.

  • Patent number: 7053364
    Abstract: The invention pertains to a safety cabinet with an interior enclosed by a housing and with a housing front comprising a working opening that can be closed with a height-adjustable front pane. The safety cabinet exhibits a fixed operating unit for controlling device functions that is integrated into the housing. A remote operating unit for controlling device functions that is spatially separated from the safety cabinet is also present. A receiver for receiving control signals emitted by the remote operating unit is also integrated into the safety cabinet. The remote operating unit not connected to the housing of the safety cabinet can be taken into the interior of the safety cabinet and removed from it by the operator without the necessity for the hands to touch nonsterile areas to operate the safety cabinet. Thereby the danger of contamination by entraining contaminants from the exterior into the interior is markedly reduced.

  • Patent number: 7028913
    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: 7013197
    Abstract: The invention concerns a climatic cabinet with specimen storage places and a transporting device and a monitoring device for specimen slides. The invention also concerns a device and a method for the monitoring of a climatic cabinet. The monitoring device is designed, with respect to its form and outside dimensions, so that it can be transported by the transporting system and can be laid on one of the specimen storage places and can be removed from a specimen storage place. That has the advantage that the monitoring device can be moved to any place with the already present transporting device, wherein not only individual specimen slides but also specimen slide cassettes can be taken to their storage places and monitored, as well as stationary and movable storage devices in a position at rest and in operation, such as cassette carrier carousels, and parts of the transporting device itself.

  • Patent number: 6806604
    Abstract: A centrifuge with a rotor set-up having at least one magnetic bearing is invented to operate a novel centrifuge. The rotor arrangement is connected with at least one permanent magnet configuration which is radially separated by small gap from a passive superconducting magnet stator. The permanent magnets which are adjusted in such a way that the escaping magnetic flux penetrates the adjacent surface of the passive superconducting magnet stator at a substantially perpendicular orientation. A driving motor unit, preferably in the form of a contactless induction engine, ensures a free and frictionless rotation. The passive superconducting magnet stator is comprised a melt textured superconducting YBCO material of high critical current density which can be cooled below its critical temperature of T=92 K using an integrated cryogenic unit to obtain the superconducting state. The stator has a preferred shape of a cylinder or hollow cylinder.

  • 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.

  • Patent number: 6173903
    Abstract: To regulate the temperature in the processing chamber of an incubator with a fault protection function, two temperature sensors are provided to measure actual temperatures or rather sensor signals, and they and their associated peripherals undergo a plausibility check during which the sensor signals may not exceed a specified difference. if the plausibility condition is met and if an error in the feedback control circuit, for example a permanently closed contact of the temperature stabilization actuator, should cause the temperature sensor signal value (actual value) to exceed or fall below a specified error tolerance band about a desired value, then control is transferred from a first feedback control circuit to a primary feedback control circuit with a controller/monitoring device.

  • Patent number: 6068586
    Abstract: A laboratory centrifuge has a housing which can be closed by a casing cover and having in the housing a rotor chamber which contains a motor-driven vertical-axis rotor to accept test tubes. During operation, the test tubes are warmed by friction. To cool the centrifuge, cooling air is pulled in through openings in the lower side of the housing and upward into the rotor chamber by the fan action created by the rotation of the rotor. The air is guided out of the rotor chamber through an air exit in a direction of flow tangential to the perimeter of the rotor in a manner that ensures low turbulence and, thus, low noise. In particular, a slit-like air exit opening is arranged between the casing cover and the top side of the housing.

  • Patent number: 6010243
    Abstract: A thermal conductivity detector system within an incubator having an atmosphere of moisture and CO.sub.2 therein is calibrated this way: in a first phase, the incubator, after ambient air being supplied thereto, is closed with respect to further gas or air admission; in a second phase, and after a predetermined time interval, a CO.sub.2 measurement is made by means of the thermal conductivity cell, and upon deviation of the measured value from a CO.sub.2 zero value, the deviation is stored and utilized for 0.2 correction of the CO.sub.2 measured value. A CO.sub.2 tolerance range of measured values of, for example, .+-.0.2 vol. % CO.sub.2 is determined. After introduction of moisture or humidity into the chamber, a third phase is initiated for a predetermined time interval and run through so often until the CO.sub.2 measured value for the entire time interval remains within the CO.sub.2 tolerance range. After successful termination of the third phase, the moisture of said value of the CO.sub.

  • Patent number: 6007473
    Abstract: A laboratory centrifuge includes a continuous metal plate comprising an underbody base plate having a rotor drive motor mounted thereon, an angled front screen which contains operating devices and display instruments, and a bending region which extends between the base plate and the front screen. At least two reciprocally parallel rows of decoupling slots are arranged between the bending region of the metal plate and the base plate. The decoupling slots form a meandering bar connection between the front screen and the base plate, by which noise generated due to imbalance at the rotor or structural noise in the direction of the front plate is considerably reduced. A conventional table centrifuge housing having a hinged lid and rotor bowl is fitted on the underbody.
