David Goldstein, also known as Dave Goldstein, founded Rooster Apparatus in April 2011. After researching scientific studies on filtered smoke particles, Dave Goldstein used his knowledge of glass to make a prototype smoking accessory intended and qualified for laboratory use. The result of David Goldstein’s efforts was the ground breaking fritted disc percolator. His revolutionary patent pending frit disc has forever changed scientific tubes, pipes and bubblers! While many companies try to imitate his work, true patent pending fritted disc technology is only available from David Goldstein’s Rooster Apparatus in Oregon.
