The Sacrament usually refers to the Blessed Eucharist (Holy Communion) which is the actual Body and Blood of Our Blessed Lord. Our Blessed Lord said that unless you eat My Body, and drink My Blood you have no life in you. It is important to give us life and help us live a holy life for God.
Your question is strangely phrased, so I'm not sure what you mean by "instrument". A Monstrance or Ostensorium is used to hold the Blessed Eucharist for Adoration, it is placed on the altar.

Roman Catholic AnswerThe central sacrament in Christianity is the most holy Eucharist, the "source and summit of the Christian life" (Vatican Council II).
