The Chemex coffee maker is a mid century design classic, based on a prototype created in 1941 by chemist Dr. Peter Schlumbohm, for his own use, from an Erlenmeyer flask and a laboratory funnel.
Widely considered the best filter coffee making system available, when used with laboratory-grade Chemex filters, the production model is fabricated from an hourglass shaped single piece of heat resistant borosilicate laboratory glass together with a polished wood collar and leather tie that serves as an insulated handle.
