CULTURE ROLLER Russian patent published in 2024 - IPC C12M3/00 C12M1/02 

FIELD: biotechnology.

SUBSTANCE: invention relates to devices intended for simultaneous cultivation in controlled conditions of various biological objects sensitive to hydrodynamic stress. Can be used in microbiological, food and medical industry for carrying out cultivation processes and testing, requiring reduced hydrodynamic stress during prolonged mixing. Device contains a bearing frame with support posts, a drive with an asynchronous electric motor and a reduction gear, a hinge, a bearing coupling, low-speed transparent discs with detachable vessels fixed on them, rotating on the bearing axis at an angle to the horizontal plane. Removable vessels used are conical wide-necked flasks, which are detachably fixed on discs-platforms, the bearing axis of which with a reduction gear and an asynchronous electric motor is pivotally mounted on a support post. Bearing coupling of bearing axle is made with possibility to change and fix angle of inclination of flasks to horizontal line at vertical displacements along the second support post.

EFFECT: use of the device provides an increase in the area of the thin layer of the culture liquid washing the side surface of the conical wide-necked flask, soft mechanical stirring and high illumination of the cultivated objects.
