This is because on instruments, there might be harmful bacteria. These (as do any organism) function by having enzymes so catalyze critical reactions in a cell. When these enzymes (and all other proteins) reach a certain temperature, they are denatured (in other words, rendered useless). Without these enzymes, the bacteria dies and the instruments are now safe to use again (and won't infect anybody else).
Because they will kill bacteria
