Test tube cabin portal v4 ( Final version)
Test Tube Cabin Portal V4 – Final Edition
Introducing the final evolution of our beloved Test Tube Cabin Portal – the V4, now featuring the most refined and functional upgrades to date:
Enhanced Colorway: A deeper, more polished finish gives the V4 a distinct and premium look.
Taller Heat Cable Cutouts: Redesigned to accommodate virtually all heat cables sold in the U.S., offering greater compatibility and flexibility in setup.
Clear Acrylic Lid: Comes standard with a transparent top for a full view into the feeding area without disturbing your colony.
Sand-Coated Feeding Floor: The textured base improves traction for ants and strategically narrows the test tube entrance, helping to preserve optimal humidity in the brood zone.
Just like previous versions, the V4 is:
Compatible with most common 16mm and 20mm test tubes, offering a snug fit with minimal to no gaps.
Designed with a smooth interior finish in the feeding arena for easy application of escape-preventing barriers like Fluon.
Built with two clearly visible logos, tube size stamps, and a spacious feeding platform for convenient colony care.
For temperature management, multiple heat cable channels are integrated beneath the cabin. While the V4 now fits more cable types, we still recommend monitoring internal tube temperature during the first 72 hours of use to ensure safe conditions. Do not exceed 86°F inside the test tube.
Whether you’re starting a new colony or upgrading your setup, the V4 delivers unmatched form and function—this is the final version, perfected for performance and ease of use.
