Avantor supplies filter flasks for vacuum filtration that feature heavier walls to insure mechanical strength. Select borosilicate glass, one-piece molded nalgene, or polypropylene models with a hose barb for connection to flexible tubing. Choose autoclavable flasks of varying capacities and graduation ranges, including microscale options. Some products include rubber stoppers and enamel graduated markings for approximate volumes. Many filter flasks are designed to ASTM specifications. Purchase items individually or in packs or cases.
