Which brand R134a refrigerant? w pic

I'm doing some maintenance on my AC system and I'm looking for small cans of R134a refrigerant with UV leak indicator but NO sealant. I've heard that most refrigerant 'top off' cans have sealant in them even though the label doesn't mention it, so I thought I better ask.

Guy at the local Oreillys said the one pictured doesn't have sealer.

Any confirmation or other brand suggestions?
