Description

Small storage clamp for cell culture bag

Technical Field

The utility model relates to the field of cell culture, in particular to a small storage clamp for a cell culture bag.

Background

Suspension cells are cells that grow in suspension in a culture medium, such as lymphocytes, independent of the surface of the support. In the conventional suspension cell culture process, fresh culture medium needs to be periodically supplemented to maintain a culture environment suitable for cell growth. The culture containers are sequentially used according to the normal use sequence of the process: multi-well plates (e.g., 96-well plates, 24-well plates, 6-well plates), culture flasks (e.g., T25 flask, T75 flask, T175 flask), cell culture bags (e.g., 1L culture bag, 2L culture bag, 3L culture bag, 10L culture bag, etc.). Most of the culture staff use a culture flask in the initial stage of culture, and the open culture increases the probability of cell pollution and the culture cost. In view of this, culture bags are used in the early stage of technological culture and in the whole culture process, and are generally prepared from materials with waterproof and breathable films, so that the risk of cell pollution can be reduced and the culture cost can be reduced by using the culture bags. However, the volume of the cell culture bag is a fixed size, and in the cell culture process, not only is the density of the cell suspension required, but also the actual contact area of the cell culture bag is required.
