Frequently Asked Questions
Which tube diameter does each cap fit?
Each flange plug is sized to the tube outer diameter: the 12 mm, 13 mm, and 16 mm caps fit corresponding tube bores. Match the cap size to your tube specification for a secure push-fit seal.
What material are these caps made from?
These caps are molded from polyethylene (PE), a flexible polymer that forms a friction seal on both glass and plastic tubes. PE is well suited to general aqueous laboratory use.
Are these caps sterile?
No. Globe Scientific flange plug caps are supplied non-sterile in cases of 1000. Sterilize via your validated method if your protocol requires it.
How are the caps packaged and sold?
Pricing is per case of 1000 caps. Each case carries a lot number for traceability, and tiered pricing is available for institutional and grant-funded orders.
