A container system includes a flexible bag, a probe port, and a probe. The probe port includes an elongated tubular member having an interior surface bounding a first passageway extending between a first end and an opposing second end, the tubular member being made of a polymeric or elastomeric material and being flexible. The probe port also includes a flange coupled to the tubular member and radially outwardly projecting therefrom, the flange being secured to the flexible bag so that the first end of the tubular member projects into a chamber of the flexible bag while the second end of the first passageway of the tubular member is accessible from outside of the flexible bag. The probe is received within the first passageway of the probe port.

The sampler (1) for connection to a bioreactor (2) filled with a cell culture aqueous solution includes a conduit (1) having a first end (101) for connection to a port (21) of the bioreactor (2), said port being intended for collecting samples of the cell culture aqueous solution, and a second free end (102), a hydrophobic air filter (11) for a free egress of air from the conduit (10) to an exterior through the second free end (102), when the conduit (10) is filled with the cell culture aqueous solution, the hydrophobic air filter (11) being impermeable to the cell culture aqueous solution, and a transparent solid container (12) incorporated into the conduit (10) between the first end (101) and the hydrophobic air filter (11). The transparent solid container (12) is adapted for filling with the cell culture aqueous solution and for a contactless analysis of the solution.

Provided is a container for cell culture, provided with a container main body and injection/discharge ports, in which an inside of the container main body is divided into a plurality of cisterns 1st and 2nd by a filter member. Thus, various operations performed upon the cell culture can be simply and efficiently performed.
