When a liquid containing bubbles flows through the cylindrical Bubble Trap, the aqueous solution is retained, while the bubbles are forced through a microporous hydrophobic membrane (made of PTFE), thereby removing the bubbles. Because the membrane is hydrophobic, the Bubble Trap is highly effective at removing bubbles from aqueous or inorganic solutions.
The top of the bubble trap features two 1/4-28 UNF threaded ports: one for liquid inflow and the other for liquid outflow. The maximum liquid flow rate is 6 mL/min. When the liquid flow rate exceeds 6 mL/min, a negative pressure device—such as a vacuum line or vacuum pump—must be connected to the bottom of the cylindrical Bubble Trap to enhance the defoaming effect.
The membrane can withstand a maximum pressure differential of 2 bar. At high flow rates, the maximum inlet (positive pressure) depends on the strength of the vacuum applied to the bottom of the diaphragm. For example, if a vacuum of 1 bar is applied to the diaphragm, the maximum inlet liquid pressure at the top is 1 bar.
Key Features:
1. Effectively removes bubbles from inorganic solutions
2. Liquid flow rate of up to 6 mL/min (in passive mode, i.e., without a vacuum pump connected) or up to 60 mL/min (with a vacuum pump connected)
3. Rapid defoaming, plug-and-play, and easy to maintain.
4. Autoclavable
The service life of PTFE hydrophobic membrane is closely related to the type of liquid used. For pure water solutions, the service life can last for several months or even years. Some buffer solutions can shorten service life; therefore, it is recommended to rinse the membrane immediately with deionized water after use to prevent salt crystal formation.
