These caps are designed for tubes with a 12 mm opening, providing a friction-fit seal. Verify your tube's inner or outer rim dimension, since fit depends on the specific tube wall thickness. Are the caps sterile? No. These plug caps are supplied non-sterile in bags of 1000. For applications requiring sterility, autoclave compatibility should be validated against your protocol before use. Why are multiple colors offered? Color coding helps labs visually separate samples by panel, patient batch, or draw order. Clear, orange, and lavender options reduce mix-ups in dense rack layouts and speed manual sorting. Do all colors share the same price and pack size? Yes. Clear, orange, and lavender are each priced at $39.20 per bag of 1000 caps. { "@context": "https://schema.org", "@type": "Product", "name": "Globe Scientific 12 mm Plug Caps, Polyethylene Push-In Closures", "brand": { "@type": "Brand", "name": "Globe Scientific" }, "description": "12 mm polyethylene push-in plug caps in clear, orange, and lavender.
