摘要:
In a closed system culture vessel to be used in an automated culture apparatus, some of the ports perform both liquid supply and gas supply functions. Culture medium is thereby made to flow always in one direction. The culture vessel is also configured so that, in the complete culture medium exchange process and the effluent recovery process for analyzing culture medium components, waste liquid medium does not get mixed into fresh culture medium.

The purpose of the present invention is to provide a valve mechanism which features a simple structure adapted to collectively control the supply of gas or culture medium to a plurality of cultivation containers for simultaneous cultivation and to enhance the reliability of the valve mechanism. The valve mechanism of the invention is a valve mechanism for opening and closing passages for liquid or gas. The valve mechanism includes: clip members adapted to close a plurality of tube passages, respectively; a multiple cam member for opening the clip members in sequence by making contact with the clip members; and a rotational mechanism for rotating the multiple cam member. The clip member includes: a spring for closing a clip thereof; and a clip contact portion for a cam contact portion of the multiple cam member to make contact therewith.

The purpose of the present invention is to decrease cell culturing vessel running cost and reduce the amount of industrial waste. A cell culturing vessel provided with a container frame and a bottom face support wherein: the cell culturing space is formed by the frame and the bottom face support; the frame is provided with a securing means for securing the bottom face support so as to be attachable and detachable; and an exchangeable culturing surface is provided on the bottom face support.
摘要:
A process for separating a first gas from a second gas, having the steps of: (1) contacting one side of a semi-permeable gas separation membrane with a feed gas mixture containing at least the first gas and the second gas, wherein the membrane divides a separation chamber into a high-pressure side into which the feed gas mixture is fed and a low-pressure side; (2) maintaining a pressure differential across the membrane under conditions such that the first gas in the feed gas mixture selectively permeates through the membrane from the high-pressure side to the low-pressure side of the membrane; (3) removing from the low-pressure side of the membrane permeated gas mixture which is enriched in the first gas and depleted in the second gas; and (4) removing from the high-pressure side of the membrane a gas mixture which is enriched in the second gas and depleted in the first gas. The membrane used is made, at least in part, of a thin discriminating layer of polyimide having the repeating formula ##STR1## wherein R is: ##STR2##

摘要:
Provided is a cell culture container that makes it possible to subculture cells without a dispensing operation using a pipette and also to prevent microbial contamination in the culture container during cell subculture. The cell culture container is provided, within a culture container (1) forming a sealable first culture zone, with a partition member (4) having a wall surface formed lower than the wall surface of the culture container and forming a second culture zone; and has means for raising and lowering the partition member while the culture container is in a sealed state. Magnets (4A, 5A, 6A) are used as the means for raising and lowering the partition member.
