NEW NON-ROTATING VACUUM JOINT MAKES BUCHLER FLASH EVAPORATORS BETTER THAN EVER! Now all Buchler portable Flash Evaporators are equipped with a new, non-rotating vacuum connection affording a vacuum-tight seal without flaking! The vacuum connection remains stationary and only the evaporator flask rotates. This design gives the instrument an exceptionally long life while maintaining evaporation only within glass and Teflon to prevent contaminating back-drip. The new Flash Evaporator is easier to assemble and clean. Replacement parts are inexpensive. All features have been incorporated without losing the versatility of Buchler's original model. Made in U.S.A. Find out more: Request Buchler Bulletin AC-FE 1000 LABORATORY APPARATUS · PRECISION INSTRUMENTS
