The yellow pigment is compounded directly into the PP matrix — not a surface coating — ensuring permanent color stability through autoclave cycles, alcohol wipes, and UV decontamination without fading or pigment migration. LabSupplies.com is an authorized Caplugs® Evergreen dealer stocking the complete 240-6388 color family (Natural, Blue, Orange, Green, Lavender, Red, and Yellow), enabling full color-scheme procurement from a single vendor for multi-user and multi-project lab organization.
