The Rigid Dosing Tube (6mm OD / 4mm ID) is a clear, hard tube designed for aquarium dosing and live culture applications where accurate placement matters. Unlike soft tubing that can curl, float, or shift over time, this rigid tube stays where you put it, making it ideal for pulling liquid from the bottom of dosing bottles or delivering air bubbles to the bottom of phytoplankton culture vessels.

Common Uses

• Dosing bottles & containers: Ensures the dosing line reaches the bottom of the bottle for consistent and reliable pickup.
• Phytoplankton aeration: Delivers air to the base of culture vessels to improve circulation and mixing.

Features

• Clear rigid construction for precise placement
• Stays straight and will not curl or float like soft tubing
• Easy to cut to length
• Compatible with standard connectors and tubing adapters
