Definitions
- Disposable bioreactor for the cultivation of cells in a nutrient medium
- the invention relates to a disposable bioreactor for the cultivation of cells in a nutrient medium, comprising a reagent container closable with a lid, which can be subjected to a shaking process in a shaking device, the reagent container having at least one chicane adjacent to the container inner wall.
- disposable bioreactors For the cultivation of cells in a nutrient medium with a cell culture volume of about 5 ml to 50 1 so-called disposable bioreactors are known.
- the process conditions have to be optimized, characterized by pH changes, oxygen input, release of CO 2 and other biological and physico-chemical parameters
- the mixing time of such small-scale bioreactor systems is an important factor in mass transfer, in particular the gas exchange rate within the liquid phase and the interphase to the headspace of the bioreactor is a critical process control parameter To improve air exchange between the sample flow in the disposable bioreactor or the Reagenzbehalter and the supernatant air.
- a Reagenzbehalter which have on their walls vertically extending ribs or wings.
- the ribs are used to scavenge the solid phase reagent within the container.
- the rubble and the Schuttelrippen the homogeneity of a solid phase reagent should be maintained or the ribs to prevent or reduce the rotation or orbital motion of the Probe Wegmaschine and improve the use of a Ruhrers turbulence of the liquid stirring.
- a disadvantage of the known Schuttelrippen is that when a cultivation of cells in a nutrient medium such ribs can lead to an impairment of the cell division process. The occurring shear forces lead to cell damage in case of larger turbulences.
- the object of the present invention is therefore to improve the disposable bioreactor or known reagent container in such a way that, on the one hand, cell division is not impaired and, on the other hand, the gas exchange rate between the fluid and supernatant air is improved so that a higher cell density is made possible.
- This object is achieved in conjunction with the preamble of claim 1, characterized in that the at least one baffle is formed as in the vertical direction from the bottom upwards helically extending web.
- the orbital shaking of the disposable bioreactor or the reagent container ruptures the surface of a liquid containing it, thereby allowing a higher exchange of air between the liquid and the supernatant air. This avoids that shear forces lead to cell damage. This leads to an increased oxygen input into the liquid. If this liquid is a nutrient medium with appropriate, e.g. contains human cells or antibody-producing hybridoma cells, a higher cell density is achieved, resulting in higher Artsitern.
- the web has a cross section with a directed away from the container inner wall convex curvature.
- the web is formed helically.
- the web can be used as a separate part in the reagent container.
- This has the advantage that usual known Reagent container can be used, in which the webs are easy and inexpensive to use.
- the web can have a round or oval cross section. It is also possible to use a kind of plano-convex cross section, wherein the plan side is adapted to the container wall, so that a slightly biconvex cross section can also be used depending on the pitch of the web and the inner diameter of the reagent container.
- the web is formed as a convex bulge on the container inner wall.
- the web can have a cross section, which is formed as elliptical or parabolic or circular section.
- the web is rounded at the transition to the container inner wall. As a result, sharp edges are avoided in the area of the bridge base.
- the ratio of lying radially to the inner wall of the container depth to transverse to the web longitudinal axis web width between 1: 2 and 2: 1.
- the ratio of depth of cut to ridge width is about 1: 1.
- the web is formed with respect to a horizontal by a pitch angle between 30 ° and 60 °, for example 45 °, rising. Basically, it is synonymous possible to choose a pitch angle between 10 ° and 90 °. A pitch of 90 ° is possible in particular if the ratio of depth of cut to web width is not greater than 2: 1.
- the lid of the reagent container is provided with at least one opening which is covered by a membrane permitting a sterile exchange of air.
- FIG. 1 a side view of a disposable bioreactor with a lid, partly in section,
- FIG. 2 a side view of the reagent container of FIG
- FIG. 3 a top view of the reagent container of FIG.
- Figure 4 a side view of another
- FIG. 5 a side view of the web of FIG. 4,
- FIG. 6 shows a side view in section and elevation in an enlarged view of an integrally formed on the container wall web
- FIG. 7 shows a side view in section and elevation in an enlarged view of an integrally formed on an inner wall web
- Figure 8 a side view in section and elevation in an enlarged view of a plano-convex separate web
- Figure 9 a side view in section and elevation in an enlarged view of a separate web with a round cross-section.
- a disposable bioreactor 1 for the cultivation of cells in a nutrient medium consists essentially of a reagent container 2 and a lid 3.
- the disposable bioreactor 1 can be used with its reagent container 2 in a shaking device, not shown, and can be subjected to a shaking.
- the reagent container 2 has at its upper end 4 a thread 5 for screwing to the lid 3.
- the reagent container 2 further has a cylindrical container wall 6 with a container inner wall 7.
- the container wall 6 is slightly conical.
- the lower end 8 is closed by a conical tip 9.
- a chicane or a web 10 is integrally formed on the container inner wall 7.
- the web 10 (see FIG. 6) has a convex curvature 11 directed away from the container inner wall 7.
- the cross section of the web 10 is designed as an elliptical section 12.
- the cross section of a web 10 ' also has a convex curvature 11 which, after a short straight transition, passes over a radius 13 into the container inner wall 7'.
- the web 14 is formed as a separate part. That is, the web 14 can be used as a separate part in the reagent container 2 ''.
- the separate, on the container inner wall 7 '' adjacent web 14 is formed with a circular cross-section.
- the cross section of the web 14 ' is plano-convex or formed as an ellipse section 12' '.
- the web 10 In the radial direction to the container inner wall 7, the web 10 has a depth of cut 15. Transverse to the depth of the groove 15, the web 10 has a web width 16.
- the web 10 rises relative to a horizontal 17 by a pitch angle 18 at.
- the pitch angle 18 is about 34 °.
- the cover 3 has five openings 19 of different sizes, which are covered towards the container interior 20 by a membrane 21.
- the pore size of the membrane 21 is, for example, 0.22 ⁇ m.
