Morphology

getter = get (semi-transparent) = get + er

The technical device sense is formed by the regular instrumentive '-er' meaning 'that which gets (removes) gases', but the specific function is specialised and may not be obvious to general learners.

Etymology

Getter comes from get 'to take' and -er 'one that does', so a getter in a vacuum is the part that 'gets rid of' or absorbs unwanted gas, like a little sponge inside the tube that soaks it up.
