Test Tube formicarium from Formiculture France
Formiculture France has another great piece of equipment. This test tube formicarium, used for when your test tube colony has grown past the first stage and needs to be fed, is very convenient.
Designed to accept a 16x160 test tube, this small test tube formicarium features a clever spring design to keep the test tube in place. Once your queen has had her first nanitics and it has become evident that they are trying to exit, you simply attach it to this formicarium where you can easily feed the workers.
The outworld comes pre decorated so you simply plug in the test tube and away you go.
You can find it on their website here. Priced from just €10.
