Scp-1373-01 to Sc-1373-06 will be found in the refrigerated containment room. Where to access specimens you need a cryogenic storage keycard. After gaining access to them you could use Scp-1373-01 to Scp-1373-06 to defend yourself against MTF or Scps.
Any other notes:
I was thinking of the laser produced from Scp-1373 should affect Scps in different ways.
