Horizon Technology Donates Original SPE-DEX 4700 to Chemical Heritage Foundation

In celebration of its 20th anniversary, Horizon Technology (Salem, New Hampshire) donated an original SPE-DEX 4700 solid phase disk extraction unit to the Chemical Heritage Foundation (Philadelphia, Pennsylvania). Horizon introduced the first solid phase extraction disk automation system 20 years ago at Pittcon 1993.

Robert Johnson, Horizon CTO and founder, and Martha Johnson, business development and founder, donated the pre-production unit of the SPE-DEX 4700 to the foundation archives. After the collection’s committee evaluated the artifact for historical significance and fit with the foundation goals, Tom Tritton, president and CEO of the Chemical Heritage Foundation, accepted the donation.
