Professional-grade sintered metal sparging stone for oxygenating and/or purging with inert gas.

Our sparging stones are made to pharmaceutical grades here in the US. They are cut to length here in our shop. Lower-quality sparging stones have oversize, inconsistent pores that make sparging slow and ineffective. Our stones are made from aerospace-grade sintered-metal, and have consistent .5µ pores. Small, consistently-sized pores create millions of uniform bubbles, thus maximizing surface area and making sparging more effective, thorough and quick. This saves you time and reduces the amount of inert gas you must use to sparge effectively.

Longer stones produce more bubbles, thus increasing surface area and decreasing required sparging time.
