Monocre solvent traps have a single core, and most have a hole that runs the entire length of the baffle. Because of their single construction, they are very stable and less prone to damage. Because the end caps are still sealed, they are allowed to have a single core until they receive Form 1 approval.
The stainless steel monocore solvent traps offers high durability and corrosion resistance at a price that is better than titanium solvent traps of the same size.
