Laboratory reactor with a reaction vessel

Abstract

A laboratory reactor ( 1 ) with a reaction vessel ( 2 ) for receiving media or substances to be processed has devices or units for processing or mixing media or components and for measuring, the devices or units being able to engage in the reaction vessel or reactor vessel ( 2 ) from above or below. On the lower side of the base ( 5 ), the laboratory reactor ( 1 ) has placement feet ( 6 ) which are mounted movably or flexibly and are connected to a weight measuring device or to sensors belonging to a weight-measuring device such that the weight of the product to be processed or a change in weight can be determined without complicated additional weighing operations.

1 . A laboratory reactor ( 1 ) comprising a closed reaction vessel ( 2 ), connected to a device for changing pressure that is adapted to accept substances to be processed or to be mixed or to be made reacting with each other, at least one processing or measuring aggregate or agitator engaging said vessel ( 2 ), a holder for receiving the vessel ( 2 ), which has a base facing a support area, several placement feet ( 6 ) are provided at a bottom of the holder, supported elastically or adjustable or movable in an upward or vertical direction against a return force or spring force and a weighing device being provided or connected or effectively connected to the placement feet ( 6 ). 
     
     
         2 . A laboratory reactor according to  claim 1 , wherein a portion of a movable support of the placement feet ( 6 ) is in an effective connection to the weighing device. 
     
     
         3 . A laboratory reactor according to  claim 1 , wherein at least one of the placement feet ( 6 ) at least partially comprises a spring-elastic material and is provided with a transfer element connected to the weighing device, movable by an elasticity of the placement foot ( 6 ). 
     
     
         4 . A laboratory reactor according to  claim 1 , wherein some of the placement feet ( 6 ) or all placement feet ( 6 ) are supported in an elastic or movable fashion and provided or connected or in an effective connection to the weighing device. 
     
     
         5 . A laboratory reactor according to  claim 1 , wherein at least two of the placement feet ( 6 ) are mechanically connected to each other. 
     
     
         6 . A laboratory reactor according to  claim 5 , wherein a connection between two of the placement feet ( 6 ) has a distance between them and the support area or at least of the two placement feet ( 6 ) are combined or connected in one piece to a wide support base, comprising or impinging two of the weighing devices. 
     
     
         7 . A laboratory reactor according to  claim 1 , wherein the elastic or adjustable or movable support feet ( 6 ) impinge levers ( 7 ) or rockers or end pieces, which cooperate with the weighing devices or are connected thereto or are in an effective connection thereto. 
     
     
         8 . A laboratory reactor according to  claim 7 , wherein the levers ( 7 ) or rockers or end pieces, movable by the placement feet ( 6 ), are provided with force measurement sensors or measuring strips or Piezo-elements as components of the weighing device. 
     
     
         9 . A laboratory reactor according to  claim 8 , wherein the force measurement sensors combine several or all of the placement feet ( 6 ) to a microprocessor or computer in a manner such that weight forces compensated by the individual placement feet are at least one of added or averaged. 
     
     
         10 . A laboratory reactor according to  claim 1 , wherein further comprising an electronic storage for recipes, in which individual components of components of mixtures defined according to their material and weight are stored and can be processed menu-controlled by way of integrated weighing functions. 
     
     
         11 . A laboratory reactor according to  claim 1 , wherein an operating, control or storage unit ( 10 ) is provided and connected to the laboratory reactor ( 1 ) or a housing in a detachable fashion and connected to drive parts located in the laboratory reactor ( 1 ) and other aggregates via radio frequency or cable connection. 
     
     
         12 . A laboratory reactor according to  claim 1 , wherein the agitator or mixer or processing aggregate comprises a torque detection function, which occurs via a power draw of a drive motor. 
     
     
         13 . A laboratory reactor according to  claim 1 , wherein a torque control is provided at the agitator or mixer or the processing aggregate, that includes settings that determine the torque. 
     
     
         14 . A laboratory reactor according to  claim 1 , wherein the device for changing the pressure, to create an overpressure or a vacuum in the laboratory vessel ( 2 ) upon it being sealed, is a pump that can be or is connected to the laboratory reactor ( 1 ) or the reaction vessel ( 2 ).
