About This Product
Filtering flasks collect the filtrate during suction filtration, with the vacuum line attached at the tubulation. On this bolt-neck design the neck finish is shaped for strength and so that a stopper seats well, and each flask is blown in special moulds from borosilicate glass that resists heat and chemicals. Graduations let the collected volume be read, across capacities from 100 mL to 5000 mL. School Educational Instrument can ship the Flasks Filtering Bolt Neck, with Tubulation to Egypt, Chile, Argentina, Guyana and Yemen.
