Frequently Asked Questions

What tube diameter do these caps fit?

These plug caps are designed for 12 mm tubes. Verify your tube's outer rim and inner bore, since plug closures seat against the inner wall for a friction fit.

Are these caps sterile?

No, they are supplied non-sterile. For applications requiring asepsis, sterilize compatibly or select a pre-sterilized closure suited to your protocol.

What material are the caps made from?

They are molded from low-density polyethylene, which delivers a pliable, snug seal and resists cracking under routine handling and refrigeration.

How many caps come in a case?

Each case contains 1000 lavender plug caps at the listed per-case price of $39.20. Bulk and institutional pricing is available on request.
