摘要:
A sensor for measuring an oxygen content in a liquid or gaseous sample has first and second sensor sections (14a, 14b). The first sensor section (14a) can be brought into contact with the sample and has a luminescent indicator dye embedded in an oxygen-permeable first polymer matrix. The second sensor section (14b) is arranged adjacent to the first sensor section (14a) and includes the same dye embedded in an oxygen-impermeable second polymer matrix. A light guide (10) guides luminescence excitation light from a light source (31, 32) to the sensor sections (14a, 14b) and guides luminescence emission light from the sensor section (14a, 14b) to a detector (39).

Device for fastening a sensor on containers with a flexible container wall, in particular mixing bags, comprising a sensor support which is fitted with a sensor, bears against an inner wall of the container wall at least with a rear subsurface averted from the sensor, and is guided with a central piece through an opening in the container wall in which the sensor support is fixed on the container wall by a clamping part which can be connected to the central piece, in which the container wall is clamped between the rear subsurface of the sensor support and on a bearing surface, facing an outer wall of the container, of the clamping part, and in which the rear subsurface bears sealingly against the inner wall of the container wall. The sensor support can also have an electronic or optical transmit unit which is connected to the sensor, in which case the transmit unit communicates in a wireless fashion with a receive unit arranged outside the container.

摘要:
A cleaning method for a filter testing device (10) including switching devices (V1–V6), external connections (12, 14, 16, 18, 20) and internal volumes (24, 26, 28, 30, VV1–VV5) that can come into contact with a fluid from a filter device that is to be tested. The cleaning method involves the steps of: selecting one or more internal volumes (24, 26, 28, 30, VV1–VV5) to be cleaned, cleaning the selected internal volumes (24, 26, 28, 30, VV1–VV5) with a cleaning fluid by correspondingly switching the switching devices (V1–V6), and removing the cleaning fluid contained in the internal volumes (24, 26, 28, 30, VV1–VV5) from the internal volumes. Also a computer program product with program parts for implementing the method of the invention or a preferred embodiment thereof, and a filter testing device adapted to be cleaned by the method of the invention.

摘要:
The invention relates to a device for detecting a sample in a longitudinal sample container (10), comprising a sample container holder (30) for holding the sample container in a housing. Said sample container holder comprises a side viewing window in the region of at least one longitudinal side of the sample container, and a front viewing window (35) in the region at least one front side of the sample container. Said device also comprises a first illumination arrangement for illuminating the sample container through the front viewing window, a second illumination arrangement for illuminating the sample container through the side viewing window, and an imaging photodetector for detecting a first image of the sample illuminated by means of the first illumination arrangement, and a second image of the sample illuminated by means of the second illumination arrangement. Said detection takes place through the side viewing window. Said device further comprises a digital data processing unit for overlaying the first and second images and for representing the resulting overlay image on a display device connected to the data processing unit.
摘要:
A connector (10) is provided for sterile connection to a complementary connector (12). The connector (10) has a housing (14) with an engagement device (16) to engage a complementary engagement device (18) of the complementary connector (12) along an engagement direction (44). The connector (10) is displaceable relative to the complementary connector (12) along the engagement direction (44) after the engagement device (16) engages the complementary engagement device (18). The housing (14) has a feed-through opening (24) for receiving a sensor (34) and a cover (22). The cover (22) is displaced relative to the connector (10) along the engagement direction (44) to close the feed-through opening (24) in a sterile manner. The connector (10) also has a sterile sensor (34) that is movable along a sensor displacement direction (52) that differs from the engagement direction (44).
