### Available end points:

- `/instruments/` - Will list all Instruments in the database
- `/instruments.json` - Will return all Instruments in json format
- `/instruments/<object_id>/` - Returns Instruments object with that id

### Available Methods:

- `GET`
- `HEAD`

### Available filters:

    "abstract": "The long path-length absorption cell (LPAC) at RAL is a 9-metre long stainless-steel vessel containing multi-pass reflective optics for broadband high-resolution spectroscopy at long optical path-lengths from 32 metres to over 1 km. The cell temperature, logged automatically to computer, can be controlled at any point between 190 and 320 K, and cooling to 77 K is also possible. A state-of-the art high-vacuum system ensures the LPAC and all external optical paths can be fully evacuated.",
