Abstract: A cell passage device for automatic passage of a suspension of biological tissue or cells from a first culture vessel into one or more additional culture vessels includes a sampling unit, a dosing unit, at least one reservoir for fluid, a pressure recipient and a fluid block. The sampling unit removes the suspension from the first culture vessel and includes at least one ascending tube and at least one pressure tube. An ascending tube receives the suspension. A pressure tube pressurizes the first culture vessel. The ascending tube and pressure tube are inserted into the first cell culture vessel and sealable with the first cell culture vessel in a pressure-proof manner. The dosing unit doses the suspension into additional culture vessel(s). The fluid block has horizontally oriented fluid channels and valves assigned them, making fluid connections with the sampling unit, dosing unit, at least one reservoir and the pressure recipient.
