Abstract
Disclosed is a cell culture tube, having in opposite end walls two respective eccentric openings which communicate with each other through an inner straight passage formed in the cell culture tube, in which the inner straight passage is tilted at an angle relative to a longitudinal axis of the cell culture tube to allow a culture medium to smoothly flow into and out of the inner passage through the openings. Also, provided is a multiple cell culture system using a plurality of the culture tubes.
Claims6
A cylindrical cell culture tube (18), having two openings which communicate with each other through an inner straight passage formed in the cell culture tube (18), wherein (a) the openings are eccentrically located on opposite ends of the cell culture tube (18), (b) the openings have an elliptical or semi-elliptical cross-section, (c) the inner straight passage extends between the two openings, (d) the inner straight passage is tilted at an angle of 1-5 degrees, and (e) said inner straight passage being tilted at an angle with a longitudinal axis of the cell culture tube to allow a culture medium to smoothly flow in and out of the inner passage through the openings, wherein one of the two openings is located at a position in contact with the side edge of an end wall of the cell culture tube and the other is located so that its circumference is spaced apart from the side edge of the other end wall of the cell culture tube.
