A modular connector designed to attach a test tube directly to a compatible Antastic Tom nest, outworld or other modular component.

The rigid connector slots into the Antastic Tom connection system, while the flexible TPU test tube fitting grips the end of the tube to create a simple transition between the test tube and the connected setup.

It is useful when a colony is ready to gain access to an outworld or nest but you want to leave their existing test tube available, allowing the ants to explore and relocate naturally rather than forcing a move.

The flexible TPU section provides some tolerance for small differences between compatible test tubes while creating a secure connection around the tube.

Containment & species suitability: Test tubes vary in diameter. Before introducing ants, check that the flexible TPU fitting grips the actual tube firmly, the modular connector is fully seated and retained, and there are no escape gaps. Recheck connections after handling or moving the setup. A secure fit does not make the enclosure escape-proof. This connector has not been specifically validated for medically significant or powerfully stinging ants such as Myrmecia and should not be relied upon to contain them.

Best suited for:

  • Connecting a test tube to an Antastic Tom nest
  • Connecting a test tube directly to an outworld
  • Allowing colonies to leave their founding tube naturally
  • Adding a test tube as an additional nesting option
  • Expanding a founding setup
  • Providing a simple transition into the Antastic Tom modular system

For important guidance on appropriate species, enclosure checks, heating and safe handling, please read our Product Safety & Suitability information before use.

Safety & containment — material and inspection guidance

Before ants can access a connection, check that both the rigid PLA modular part and flexible TPU tube fitting are fully seated. Test-tube diameters and printed part tolerances can vary: never force an unsuitable fit or rely on a loose one. Inspect the joint after handling or moving the setup and replace any cracked, distorted or loose component.

Temperature precaution: Avoid allowing PLA components to reach 35°C or above. Keep them out of direct sunlight and away from uncontrolled heat sources. Check actual equipment temperature where heating is used. This is a precautionary use limit, not a certified material rating.

What’s included

1 × Ant Test Tube Connector with its rigid modular fitting and flexible TPU test-tube sleeve. Test tube, nest and outworld are not included.

Dimensions and compatibility

Materials: rigid PLA modular connector and flexible TPU test-tube fitting.

Designed for compatible test tubes, typically around 16mm outside diameter (OD). Measure the actual tube's outside diameter at the connection point; the previously listed 14–15mm internal diameter was not an appropriate fitting measurement.

The modular end fits compatible Antastic Tom ports. Check the TPU grip, retention and full perimeter for gaps before introducing ants.

Who it’s for

For keepers connecting a compatible test tube to an Antastic Tom nest, outworld or modular component without forcing a colony to leave its tube.

Setup and use

  • Measure the tube's outside diameter and check the sleeve grips without forcing it.
  • Fit the modular connector securely in the matching Antastic Tom port and confirm any required retention clip is engaged.
  • Seat the tube firmly in the TPU fitting and inspect all edges for gaps before giving the colony access.
  • Allow ants to move naturally; do not tip or pour the colony into a connected nest.

Care and maintenance

Routine checks

  • Inspect the rigid PLA connector and flexible TPU fitting before use and regularly while connected.
  • Check for cracks, splits, stretching, warping or any change that causes the test tube or modular connection to fit loosely.
  • Check the full connection for gaps before allowing ants access.
  • Do not continue using the connector if the tube can move excessively, the TPU no longer grips securely or any part is damaged.

Cleaning

  • Remove the connector from the colony setup before cleaning.
  • Rinse or wipe the PLA and TPU components with lukewarm water.
  • Use a soft brush or cotton bud to remove debris from the opening and connection surfaces.
  • Allow the connector to dry completely before refitting.

Do not force an unsuitable test tube into the TPU fitting. Avoid boiling water, dishwashers, solvents, bleach and strong cleaning products, and keep the connector away from excessive heat and direct sunlight.

Frequently asked questions

Does it fit any test tube?

No. Check the tube's outside diameter and the grip of the supplied TPU sleeve. Test tubes with similar capacities may have different external sizes.

Can ants move between the test tube and nest?

Yes, when the connector and joined equipment are compatible and securely seated. Give the colony time to move voluntarily.
