- the suspension rose and was clarified by sedimentation of the lines / particles (vertical precipitation). The particles fell back against the flow direction out of the separator volume into the culture volume VK (FIG. 7).
- the clarified solution was collected from the crop stream collector 320 of the separator tube 310 and discharged through the suction tube 340.
- the surface A of the separator tube corresponds to its Kreisförmi en cross section and is according to Eq. III calculated.
- the particle ytem PAN-X (polyacrylonitrile, spherical particles from Dralon GmbH) was used as the model particle for the investigation of the separation efficiency of the reactor bottle according to the invention with integrated cell enabels in cell culture.
- the particle size distribution and the particle sinking rate were compared since these are the determining factors for the sedimentation.
- the particle size distribution was determined by the laser diffraction method (Mastersizer 2000, measured according to the instruction manual). The application of the results is carried out as a particle volume in%, based on the total volume, as a function of the particle size in ⁇ .
- the modal value XM OÜ indicates which particle size is most frequently represented by volume and was about 21 ⁇ .
- the rate of descent was analyzed by means of a sedimentation balance.
- a suspension was prepared which has the same concentration as that used in the experiment.
- a temperature of 20 ° C was chosen.
- Sinking rates v s measured from these experimental conditions, from 0.129 m / h to 0.137 mh, were determined on different PAN-X batches and correspond to the conditions of non-obstructed sedimentation.
- C HO cells have a sedimentation rate of 0.0145 m / h [Searles J A, Todd P, Kompala D S, Biotechnol Prog (1994) 10: 198-206] and are relatively slow-sedimenting cells.
- the hybridoma cell line AB2-143.2 has a sedimentation rate of 0.029 m / h [Wang Z, Belovich J M (2010) Biotechnol Prog 26 (5): 1361-1366].
- the results showed the clear advantage of the conical harvest current collector.
- the retention performance of this separator was surprisingly almost constant at separator lengths 1 of 90 to 143 mm in the entire examination area. In harvest crop collectors with sudden expansion, the separation efficiency increased with increasing separator lengths 1 from 90 to 170 mm, but without fully achieving the performance of the conical cross-sectional constriction.
- the Klär perennial insect v of Ab s cheiderrohre s corresponds to the speed of the vertically rising medium and has according to Eq. IV direct influence on the Partikei Wegiens.
- FIG. 13 A comparison of the performance of various separation systems is shown in FIG. 13 in the form of retention levels R over the treatment surface load.
- the test results prove a nearly equivalent retention performance of all separators over the entire areas of the examined Kiär vombelastung of 0.025 to 0.2 m / h with slight Vortei len for the cube.
