PURPOSE:To efficiently stir a culture solution without damaging cells, etc., by feeding the culture solution to an inner pipe of a horizontal double pipe from the outside of an exterior pipe. CONSTITUTION:Covers 14 and 15 are detachably attached to flanges 10 and 11 of a cylindrical outer pipe 12 by clamps 16. In the outer pipe 12, a cylindrical inner pipe 19 made of glass having both open sides is rotatably sealed through an oil seal 20 within in the outer pipe 12. Magnets 22 for fixing a shaft position and magnets 23 for fixing radiated position are laid in the inner pipe 19 and magnets 25 for fixing shaft position and magnets 26 for fixing radiated position are set in the outer pipe 12. Electric current is successively sent to each induction coil 24..., a magnetic is transferred in the circumferential direction and a magnetic material 21 in the inner pipe 19, namely the inner pipe 19 is rotated.
