Keep your ant colonies and test tubes neatly organized with our Stackable Test Tube Rack.
The rack is made from thick, strong, crystal-clear acrylic, giving you a sturdy storage solution while keeping all your test tubes clearly visible. Each layer holds up to 10 test tubes and is designed for universal use.
 
Universal Test Tube Storage
The rack can hold almost any test tube with:
A diameter of up to 20 mm
A minimum length of 50 mm
 
This makes it suitable for a wide variety of test tubes and ant keeping setups.
 
Optional Test Tube Adapters
For our standard 16 × 150 mm test tubes, optional adapters are available that grip the tubes firmly and help prevent them from sliding or falling out of the rack.
 
The same adapters can also be used with 16 × 100 mm test tubes. Simply install the adapter on the front panel instead of the back panel to securely hold the shorter tubes in place.
 
Stack Them High
One of the biggest advantages of this system is its stackability. Multiple racks can be stacked on top of each other, allowing you to store a large number of colonies while using very little shelf or desk space.
 
The layers can be secured together using dedicated acrylic locking pieces. Once connected, the complete stack can be lifted and moved as one unit instead of having to move every layer individually.
 
The acrylic securing pieces are available separately within this listing, allowing you to build and expand your setup exactly how you want.
