The phrase "a given preparation" is correct and usable in written English.
It can be used when referring to a specific preparation that has been previously mentioned or is understood in the context.
Example: "In the experiment, we will analyze the effects of a given preparation on the growth of the plants."
Alternatives: "a specific preparation" or "a particular preparation".
