When changing resin types, always change both the tank and the cartridge. Remove the cartridge before removing the tank to prevent the cartridge valve from dripping resin into the printer interior. Use a different resin tank for each type of Formlabs resin.

Whenever a resin tank is not installed in the printer, store it in its case. For newer resin tanks, the shipping box also acts as the tank case. If the inside of the tank case or the bottom of the resin tank have liquid resin on them, clean them before storing the tank. Keep the case covered to prevent ambient light from curing the liquid resin in the tank.
