ABSTRACT:
The method of filtering and metering a liquid sample set forth herein includes the steps of providing a first recipient (1) in which the sample is placed, the volume of the sample being greater than the quantity to be metered, providing a second recipient (2) into which the sample is decanted in the same proportions, interposing filtering means (7) between the first and second recipients, decanting into the first recipient a quantity of the sample less than the excess quantity contained in the second recipient and providing a third recipient (3) into which is decanted from the second recipient the desired quantity of liquid samples. The method may be employed for example in processing the adenosine triphosphate (ATP) molecule.
