Description

The GPCA40 bench allows the study of gas-liquid absorption.

The mixture to be separated will be composed of air and carbon dioxide (CO2). The mixture will be fed into the bottom of the column. The solvent allowing the separation will be water. The solvent will be fed from the top of the column. The mixture and the solvent will intersect within the column. The solvent will trap the CO2 molecules therefore, at the top of the column, will recover the purified air, and at the bottom is recovered a mixture of water and CO2.
The robust design of this device makes it suitable for use in schools.
The equipment is set up on an Anodized aluminium frame on casters wheels. This gives it great strength and a flexibility of integration into your premises. The manufacture of this equipment complies with the European standard for machinery manufacturing.

The bench is installed on an aluminum profile structure equipped with four directional brake casters.
It has an electrical box with general power disconnector and 30mA differential circuit breaker.
