|The BST bubble trap is designed to capture gas bubbles before they enter the flow cell. The bubble trap also acts as a pulse damper to reduce pulses in nutrient flow caused by peristaltic pumps.|

||Bubble Trap Operations :|
At the start of the experiment, while liquid is pumped through the bubble trap and flow cell, open the valve to provide a small reservoir of liquid in the syringe barrel (2-3 ml). Turn the valve to the off position. The liquid in the syringe barrel acts as a reservoir to take the place of the captured gas bubbles. The valve can be opened during the experiment to maintain a liquid reservoir in the syringe barrel as needed.
|Typical System Set-Up|
|This schematic shows the simplest system set-up. In some cases a mixing chamber may be added to provide aeration, chemical addition or temperature control. For high shear flows with the BST FC 93 the flow cell may need to be positioned in a recirculating loop.|
