PFA box / square trough with lid for acid-alkali resistant storage and cleaning. All sizes carry the same flat price at the family's highest first tier (two listings, $1,500 and $1,600). The lid-only option and an option with an incomplete dimension are not offered; one listing's 45L capacity for the 240mm tank is a unit error (about 4.5L by its dimensions) and is corrected here.
