Ventilated test tube cap

Ventilated Test Tube Cap – Safe, breathable and reusable

Are you raising a young ant colony in a test tube or preparing your ants for hibernation? Then this ventilated test tube cap is the perfect upgrade for your rearing setup! Using cotton wool as a seal can sometimes be difficult when feeding or can quickly get dirty. This sturdy plastic cap offers a hygienic, reusable and professional alternative.

Maximum ventilation without escape risk

The cap is equipped with a fine-mesh ventilation grille that ensures a continuous supply of fresh air into the nest tube. This creates a healthy microclimate without the air becoming stale. At the same time, the cap seals the opening so precisely that even small workers cannot squeeze through.

Ideal for young colonies and hibernation

When a queen has just produced her first workers, care and feeding usually take place inside the test tube. With this cap, you can open and close the tube in an instant to offer a drop of sugar water or a small insect. Furthermore, the cap is extremely suitable during hibernation, when ants need extra rest and stable air circulation.
