[Nhcoll-l] shelving in wet collection

[Callomon,Paul]

Powder coating: it can indeed fail - we have had some (rejected) cabinets where it came off in patches. This is always due to poor metal preparation before coating or inadequate baking (or both). A good factory has proper degreasing and keying processes, and ovens that fully bond the coating.

Shelf liners: stainless is heavy! You can line steel or mesh shelves with Kydex or similar high-melting-point plastic sheet to protect the shelf and provide uniform rhesis (resistance to sliding). See: https://www.researchgate.net/publication/337950870_An_improved_design_for_the_storage_of_fluid-preserved_specimens_in_small_to_medium-sized_containers
If the shelf has to be perforated for fire reasons, though, you will need to find a liner that allows through-flow. As long as it has a higher melting/flash point than your jar lids, it should pass inspection.
