Prototype

Prototype is the common designation for a first working model of a new invention, used for trial runs.

History
In 2371, the Obsidian Order tested a prototype quantum stasis field, which prevented a Changeling from altering its biomolecular structure. 

In 2373, Starfleet Science developed a prototype of a device called a polaron emitter, designed to expose Changelings by rendering them unable to maintain solid form. The untested nature and the complicated means of placement and activation made Miles O'Brien remark: "I hate prototypes". 

Concerning starships, Starfleet prototypes had an "NX" prefix in the registry number, as opposed to the normal "NCC" (this was different from the United Earth NX prefix, which indicated the NX class), and were typically the first vessels in their class. Once certified for operational status, however, these prototype vessels usually revert to a more standard NCC prefix.
