摘要:
The invention relates to the use of single- or multilayer plastic web plates in a sloped channel-type solid material separator with a lamella package.
摘要:
The invention relates to a separator for retaining and recirculating cells in a continuous-flow- or batch-flow-type plastic bag or bottle which can preferably be operated outside of a bioreactor. Additionally, the invention relates to a method for retaining and recirculating cells within or outside of a bioreactor. The invention further relates to a method for producing the separator according to the invention.
摘要:
The invention relates to a method for reducing deposits during the cultivation of organisms, particularly cell cultures, which tend to agglomerate or adhere to the bioreactor and the elements thereof, or in which cell debris or substances easily agglomerate or adhere.
摘要:
The invention relates to a method for removing and/or selectively separating peptides and proteins from a solution by means of a controlled crystallization process.
摘要:
The invention relates to a reactor designed as a disposable element, a container for receiving the reactor, a device comprising a reactor, and a drive unit for generating a rotating-oscillating motion of the reactor, and the use of the device for cultivating cells and/or microorganisms.
摘要:
The invention relates to a bioreactor, to the use of the bioreactor for culturing microorganisms or cell cultures, and also to a method for culturing microorganisms or cell cultures.
摘要:
The invention relates to a reactor tank designed as a disposable element, comprising a cover and/or optoelectronically readable sensor patches fastened in the interior, a reactor, comprising the reactor tank and a reactor tank accommodating periphery, which comprises a reactor tank retainer and optionally an optoelectronic measuring system for reading sensor patches, wherein the reactor tank retainer is coupled to a drive unit for producing a rotational oscillating motion of the reactor tank about a center vertical axis of the reactor tank, and the use of said device to cultivate cells and/or microorganisms.
摘要:
The invention relates to a novel gassing system that can be used particularly but not exclusively in biotechnology for supplying oxygen to cells or microorganisms. The gassing system comprises a bubble column and a distributor. There is furthermore a fluid medium in the tank that is to be supplied with gas. A vector is used as a transport means for the gas. The gas is incorporated into the bubble column and taken up by the vector here. The vector is applied to the fluid surface in droplet form via the distributor, sinks down into the medium and releases a portion of the absorbed gas to the medium. There is a collection device on the floor of the tank wherein the vector drops coalesce and enter the bubble column again. The invention furthermore relates to a bioreactor comprising the novel gassing system. The invention furthermore relates to a method for gassing a fluid medium, preferably an aqueous suspension comprising cells or microorganisms.
