How can i quarantine snails

I want to get some snails but All the fish stores have diseases what's the best way to sanitize assassin snails for my tank to kill these pest snails.

I highly doubt you will get pest snails from assassin snails. If you are worried about pathogens then quarantine them for a couple of weeks in a spare tank or large Tupperware container making sure to keep the water clean.
