Test tube rack for ant rearing

The test tube rack is an accessory for ant rearing. Test tubes are used by entomologists for catching and rearing ants. This tube rack is designed to hold tubes horizontally and prevent them from rolling. Test tubes are tilted from 1 degree, helping tubes to stay in place and preventing flood.
Designed for 16,3mmx160mm test tubes.
