Microbial testing device

A sanitation assembly () comprising a first chamber () with a first volume () for receiving a first fluid, and a second chamber () with a second volume () for receiving a second fluid, wherein the first volume () communicates with an outlet () of the assembly () via a first valve mechanism () configured to allow discharge of the fluid from the first volume () to the outlet () at a predefined first opening pressure, wherein the second volume () communicates with the outlet () of the assembly () via a second valve mechanism () configured to allow discharge of the fluid from the second volume () to the outlet () at a predefined second opening pressure, and wherein the predefined second opening pressure of the second valve mechanism () is higher than the predefined first opening pressure of the first valve mechanism ().

Sanitation assembly and method

The present invention provides a calibration device for an optical detector comprising a light emitting diode, and an electronic circuitfor driving the light emitting diode, wherein the electronic circuitis a constant current generator configured to supply a constant driving current to the light emitting diodein the range of 0.5 to 25 &#x3bc;A. Furthermore, the present invention provides a setting device for setting at least one calibration point for a calibration device as described above. The setting device comprises a light detectorconfigured to output a signal representing the light emission intensity of a calibration device under examination, a controllerfor controlling the constant driving current of the calibration device under examination, and a calibration point setting meansfor setting at least one calibration point for the calibration device under examination.

Calibration device for an optical detector and setting device for setting calibration points for the calibration device

A sample preparation device () comprising a first chamber () containing a membrane support () on which a membrane () is placed or can be placed, an inlet () to the first chamber () and an outlet () from the first chamber (), at least one second chamber () provided with or adapted to be provided with an anaerobic generation means () and/or an anaerobic detection indicator, wherein the at least one second chamber () is connected to the first chamber () by a communication path (), wherein the communication path () is liquid-tightly closed by a tap device () in a first position (A) of the tap device () and is adapted to be opened to allow fluid communication between the first chamber () and the at least one second chamber () in that the tap device () is moved to a second position (B) of the tap device ().
