The lavender color is compounded directly into the PP matrix — not a surface coating — so it remains stable through autoclave cycles, alcohol wipe-downs, and UV decontamination without fading or pigment migration. The complete 240-6388 rack family is available in seven colors (Natural, Blue, Orange, Green, Lavender, Red, and Yellow), enabling a full color-scheme procurement from a single authorized source for multi-user and multi-project bench organization. LabSupplies.com is an authorized Caplugs® Evergreen dealer shipping from USA inventory, with tiered pricing available for high-volume institutional, clinical, and grant-funded laboratory accounts.\u003c\/p\u003e\n\n\u003ch2\u003eFrequently Asked Questions\u003c\/h2\u003e\n\u003cp\u003e\u003cstrong\u003eCan these racks be autoclaved between experiments?\u003c\/strong\u003e\u003cbr\u003eYes.
