## Description

Our miniature gas dispersion tube is designed to provide aeration or gas dispersion in applications with limited space. The small size of this device makes it well-suited to placement in small reservoirs where large tubes cannot fit. The GD tube displaces very little fluid, occupies minimal space, and provides very fine bubbles (porosity of the glass frit is 4 to 8 µm). A high-quality flow valve is supplied for controlling the gas flow rate. The GD tube can be chemically cleaned (e.g., 1 N HCl) to ensure long life and optimized performance.

## Features

- small size
- fine pores
- includes flow control valve
- displaces very little volume
- easy to maintain
