Reactor device

The invention relates to a reactor device (1), comprising: at least one vessel (100) having a first end section (101) and an opposing second end section (102), wherein the two end sections (101, 102) each delimit an opening (O, O') of the at least one vessel (100), so that a fluid medium (F) can enter the at least one vessel (100) through one of the openings (O), flow through the at least one vessel (100), and leave the at least one vessel (100) through the other opening (O'), and a first manifold (200) comprising a first recess (201) and a first aperture (202), wherein the first end section (101) of the at least one vessel (100) is designed to be arranged in said first recess (201) in an operating position of the first manifold (200), so that the opening (O) delimited by the first end section (101) of the vessel (100) is in fluid communication with said first aperture (202) and fluid medium (F) can be discharged into the vessel (100) or can be drawn off the vessel (100) through said first aperture (202) of the first manifold (200). According to the invention, the reactor device (1) comprises a first seal (10) for sealing a gap between the first end section (101) of the at least one vessel (100) and a circumferential inner side (201 a) of the first recess (201) in the operating position of the first manifold (200), wherein the first seal (10) encompasses the first end section (101) of the at least one vessel (100) and rests with an outer side (10a) against said inner side (201 a) of the first recess (201) of the first manifold (200).
