Frequently Asked Questions

Which test tubes do these flange plug caps fit?

They are sized to fit tubes with 12 mm, 13 mm, and 16 mm outer diameters. Select the SKU matching your tube diameter, as the flange plug seats into the tube mouth.

Are these caps sterile?

No. The flange plug caps are supplied non-sterile and are intended for routine, non-aseptic applications such as storage, transport, and general benchwork.

What material are the caps made from?

They are molded from polyethylene, a flexible plastic that allows the flange to compress and seat firmly for a push-fit seal.

Each case contains 1000 caps, and the listed price is per case. Lot numbers on every case support traceability for accredited lab workflows.
