Versafill Dispensing System The Versafill Dispensing System has been successfully used since 1979 to manufacture biomedical products such as RIA and EIA diagnostic test kits. The gentle sinusoidal pumping motion is ideal for dispensing biological products such as protein solutions, latex solutions, or delicate cell suspensions. The proven accuracy and dependability of positive displacement metering pumps are combined with solidstate controls and stepping motors for cost effectiveness and high reliability. The Versafill Dispensing System utilizes the most advanced technology. A...

Pump Tower The microprocessor controls pump speed and the number of pump strokes per dose. Each pump can be independently calibrated to deliver the same or different volumes. The same or different solutions can also be delivered by each pump. Dispense volumes from 3µL and up can be dispensed with accuracy better than ±1%. The desired volume is easily set by means of a calibrated flow control ring or flow rate indicator. The valve-less pumping function is accomplished by the synchronous rotation and reciprocation of a ceramic piston in a precision mated ceramic liner. One complete piston...

Conveyor Illustrated here is the Versafill Dispensing System configured with the microplate conveyor. It’s stepping motor drive results in very high product positioning accuracy. The microprocessor automatically senses plates and controls indexing and dispensing. The adjustable guide rail enables loading microplates in either the 8 or 12 way direction. The gently ramped acceleration maximizes throughput and operator comfort. Other conveyor designs are offered for filling a variety of different products. Automatic stack feeders and accumulators are also available. User Test Data Following is...
