摘要： A blending pump assembly for accurately maintaining the proper ratio of two fluid components. Flow of a first fluid is utilized to drive a fluid motor, which in turn drives a pumping mechanism to inject a proportional amount of a second fluid into the flow of the first fluid. The fluid motor and pump are sized so that a predetermined ratio between the two fluids is maintained regardless of changes in pressure and flow rate of such first fluid.

摘要： An electromagnetic vibratory microplate shaker is disclosed of simplified design and improved mixing capability over previously known microplate shaker devices, comprising an electromagnetic drive assembly mounted within a rigid base and operatively connected to a microplate support tray. The support tray is in turn supported from below by a plurality of leaf springs which are tilted approximately 20° from vertical. During operation, an electromagnet is rapidly energized and de-energized causing an armature of the drive assembly to be pulled in and released up to 7,200 times per minute, in turn imparting a reciprocating vibration to the support platform and the microplates held thereon. Such a vibration causes eddy currents to be created within the individual microplate wells which have both horizontal and vertical components, thus ensuring thorough mixing of the contents of each microplate well irrespective of the diameter of the well, while keeping suspended solids truly suspended during the mixing cycle.

摘要： A microplate cover seal applicator comprising a downwardly spring-biased roller mounted in a pivotal arm which pivots the roller into and out of operative contact with the top face of a microplate. The lower face of the microplate is seated in a well formed in a horizontally moveable platen which is supported on a table-top frame. The platen is manipulated by a rotary handle to repetitively translate the platen in a horizontal forwards and back direction. Suction cups are provided at the base of the frame for temporarily affixing the frame to a work surface, such as a table top surface.

摘要： A dispensing valve for fluids is disclosed which provides for ease of use by requiring only a minimal force exerted on the valve actuator to maintain the valve in an open position. A resilient valve actuator having the characteristics of a nonlinear spring is provided at an actuator end of the valve body and operatively connected to a plunger; with the opposite end of the plunger mounting a resilient valve seal that serves to pen and close a plurality of port openings. The valve may be manufactured with a variety of port configurations to provide for the dispensing of fluids of varying viscosities. The valve body and actuator are formed to allow the dispensing valve to be sterilized through high levels of radiation and through high temperature steam and chemical sterilization processes without degrading the valve structure or operation.

摘要： An electromagnetic vibratory microplate shaker is disclosed of simplified design and improved mixing capability over previously known microplate shaker devices, comprising an electromagnetic drive assembly mounted within a rigid base and operatively connected to a microplate support platform. The support platform is in turn supported by a plurality of horizontally arrayed leaf springs. During operation, an electromagnet is rapidly energized and de-energized causing an armature of the drive assembly to be pulled in and released up to 7,200 times per minute, in turn imparting a vertical reciprocating vibration to the support platform and the microplates or multi-tube racks held thereon. Means are provided for adjusting the amplitude of the vibration as necessary to enable the entire volume of liquid within each microplate well or tube to be vertically displaced within the well or tube during each vibration cycle, thus ensuring thorough mixing of the contents of each microplate well or tube irrespective of its diameter, while keeping suspended solids truly suspended during the mixing cycle. Also provided is a static indicia of amplitude of vibration fixedly mounted on the support platform to enable the user to determine the optimal vibrational amplitude to use for a particular series of microplates or multi-tube racks being vibrated.

摘要： A drip resistant dispensing valve for fluids is disclosed, which provides a dispensing outlet configured to minimize the tendency for fluid to drip from the valve following a dispensing operation. The dispensing outlet exhibits curved interior surfaces and a curved outlet face construction; the face situated a distance away from the valve body. Such construction assists in minimizing the retention of fluid on the surfaces of the dispensing outlet, and migration of the fluid to surfaces outside of the dispensing outlet that could tend to promote growth of biological contaminates and/or provide additional surfaces that could pool fluid following a dispensing operation and thereafter drip from the valve. A shell is provided around the dispensing outlet to assist in avoiding contamination of the valve and of the fluid being dispensed through the valve, and to aid in positioning a receptacle for receiving fluid from the dispensing valve.

摘要： A method of mixing fluid samples using an electromagnetic multidirectional shaker is provided. The shaker has a first electromagnet driving a first support panel in a first direction, and a second electromagnet driving a second support panel in a second direction. The first electromagnet is affixed to a base and is operatively attached to the first support panel which is suspended from the base via one or more first spring members. The first spring members are configured to bias the first support panel to an at-rest position after it has been displaced by the first electromagnet. The second support panel is in turn supported above the first support panel by one or more second spring members. The second electromagnet is affixed to the first support panel, and is operatively attached to the second support panel. The second spring members are configured to bias the second support panel to an at-rest position after it has been displaced by the second electromagnet.
