ABSTRACT:
An improved precision diluter/dispenser device is provided with features for effecting automatic compensation for non-linearity of aspirated fluid volumes of the particular piston and cylinder syringe assemblies that are included with the diluter/dispenser device in order to enhance the accuracy of the device by varying the piston stroke length in order to correct for non-linearity of aspirated or dispensed fluid volumes. Suitable correction factors are programmed into the control mechanism of the device in order to automatically make the necessary adjustments in stroke length so as to significantly enhance the linearity of the movement of fluid volumes throughout the working volume of the piston and cylinder assembly, whether the movement of fluid be of a very small percentage or a very large percentage of the volume capacity of the assembly. Additionally, an improved seal assembly is provided within a precision diluter/dispenser device in order to enhance the accuracy and precision life of the device and to reduce service requirements.
