Yes, Sparging Stones have been shown to remove dissolved Oxygen (or CO2) from Water or Wine. The efficiency of Sparging is influenced by many factors, such as Bubble Size, Contact Time between the Gas and Wine, Temperature of the Wine, Gas Pressure, and the Flow Rate of Gas in relation to the Flow Rate of […]
Considerations for keeping gases dissolved in solution when using sparging stones for HPLC.
Question: I am using the sparging stones (MTC catalog# 48222-06) in my production lines feeding nitrogen into solution. After switching to a bigger dish with more volume, I noticed that the concentration of nitrogen does not reach the same level anymore. What can you suggest for a sparging stone that can handle higher flow rates (current method around […]
How To Clean Sparging Stones and In line SS Filters. – Tips
Inlet stainless steel filters also known as Sparging Stones, can be cleaned by ultra-sonication in 30% Phosphoric Acid, clean afterwards with DI Water (ultra-sonication) and then Methanol (ultra-sonication). Same would be true for all metal filters, like Inlet Filters and more. But be aware, only the metal part! No PEEK Rings, Connectors or Housings. Step […]

What is the pressure limit of the stainless steel sparging stones?
All the sparging stone products are rated to 1000 bar. However it is important to note that the tubing used and the connection of the tubing to the device may not perform at this pressure rating. The pressure limit of sparging stone is not for the filters/spargers, but for the connections. Mobile Phase Filters Ordering Information
Your sparging stones with stems are listed as 1/8 or 1/16″ ID. Shouldn’t this be OD?
In the case of certain types of the sparging stones, the ID of the stems fits around the OD of the low pressure tubing. The following schematic should clarify. The ID of the sparging stone stem and the OD of the low pressure tubing are the same (red lines). The OD of the sparging stone stem […]
