Runs spirit into glass container that's pristine (8)
I believe the answer is:
virginal
'pristine' is the definition.
(synonyms)
'runs spirit into glass container' is the wordplay.
'runs' becomes 'r' (cricket abbreviation).
'spirit' becomes 'gin' (alcoholic spirit).
'into' is an insertion indicator.
'glass container' becomes 'vial' (I've seen this in another clue).
'r'+'gin'='rgin'
'rgin' placed inside 'vial' is 'VIRGINAL'.
'that's' is the link.
(Other definitions for virginal that I've seen before include "in immaculate condition" , "Unblemished" , "Untouched - spinet" , "Untouched - old keyboard instrument" , "Pure - very early keyboard instrument" .)
