Which Configuration Do I Need?

1,000 caps in one bag. For MTC 12 mm rimless tubes including T1111, T1121, T1211 and T1221.

20 bags of 1,000 caps, 20,000 total. For MTC T1411 and T1421 13 mm tubes.

Other tube brands

Nominal outside diameter alone does not establish plug fit. Confirm the tube opening and manufacturer guidance.

Diameter First, Order Quantity Second

A plug closure must match the intended tube opening. The manufacturer supplies these as separate accessories to its rimless tube range; no leak-proof, pressure-rated or transport-certified seal is established for these caps.

Typical Applications

Closing matching MTC rimless tubes
Accessory replenishment for general laboratory workflows
Bulk tube-and-cap assembly where cleanliness requirements are verified

Confirm material compatibility and your method’s requirements before use. No additional performance or regulatory certification is implied.

Practical Bench Tip

Check the cap catalog number against the matching tube family before opening a bag. Do not use a plug cap as evidence of a leak-proof transport system.

Frequently Asked Questions

Are these an alternative to Falcon polyethylene snap caps?

Both are polyethylene tube closures, but the closure design differs. Falcon 352003 tubes are supplied with dual-position polyethylene snap caps; these MTC accessories are plug-type caps for the listed MTC 12 or 13 mm rimless tubes. This is an alternative closure format, not a claim that MTC caps fit Falcon tubes or provide the same vented/closed operation. Trademarks belong to their respective owners; comparison does not imply endorsement, affiliation or common manufacturing origin.

Does this listing include test tubes?

No. Both variants contain caps only.

Which cap is for 12 mm MTC tubes?

T1211-C is listed for the 12 mm rimless tube family: T1111, T1121, T1211 and T1221.

Which cap is for 13 mm MTC tubes?

T1411-C is listed for the 13 mm family, T1411 and T1421.

Why is the 13 mm order so much larger?

T1411-C contains 20 bags of 1,000 caps, 20,000 total. T1211-C contains one bag of 1,000. These are not equal-size packs.

What material are the caps?

The manufacturer’s ordering table identifies PE, polyethylene.

Are the caps sterile?

The reviewed table does not separately confirm sterility for the cap catalog numbers. The matching rimless tubes are non-sterile; do not infer a sterile cap supply.

Will they fit any 12 or 13 mm test tube?

No universal cross-brand fit is established. Nominal tube diameter is not an internal-bore or cap-fit tolerance.

Compatible accessory: Matching MTC Bio rimless test tubes (tubes only). T1211-C plug caps fit the 12 mm MTC tube formats T1111, T1121, T1211 and T1221; T1411-C plug caps fit the 13 mm MTC tube formats T1411 and T1421. Tubes and caps are sold separately. This catalog-specific match does not establish cross-brand fit, a leak-proof seal or sterile cap supply.
