There isn't a single, universally accepted scientific term for "equipment put together for a science experiment." However, there are several terms you could use depending on the context:

General terms:

* Apparatus: This is a common and general term for any collection of equipment used for a specific purpose, including scientific experiments.

* Setup: This term emphasizes the arrangement and configuration of the equipment for the experiment.

* Experimental setup: This is a more specific term that explicitly refers to the equipment and its arrangement for a scientific experiment.

Specific terms:

* Instrumentation: This term emphasizes the use of specific instruments, like microscopes or spectrometers.

* Experimental design: This term refers to the overall plan for the experiment, including the choice of equipment and the way it is used.

The best term to use will depend on the specific context and what you want to emphasize. For example, if you are describing the specific instruments used in an experiment, "instrumentation" would be appropriate. But if you are talking about the overall arrangement of the equipment, "setup" or "experimental setup" would be more suitable.
