This red film test tube holder is designed for ant keeping and works especially well for founding queens or small colonies. The translucent film filters out most visible-spectrum light, reducing stress while still allowing clear observation of your ants, a preferred method among experienced keepers.
Lightweight and foldable, this box also functions as a basic display rack or organizational tray for test tubes. While not as strong as our solid plastic Display Rack or Test Tube Rack, it’s ideal for home setups and light-duty use.
Manufactured from 0.35 mm high-transmission film, it covers approximately 80% of the tube’s length. Ships flat with protective film on both sides and requires no glue or tools—just simple folding.
Commonly used in our Test Tube Array Formicarium and Customizable Inserts with Test Tube systems. Available in configurations for 1, 2, 3, or 4 tubes and supports the most common test tube sizes.
