Aced Glass borosilicate glass filtration apparatus meant to accomodate 75 mm membrane filters. This erlenmeyer flask would require a PTFE Ace-Thred adapter to join the glass funnel, sized at 80 mm on top and 50 mm on the erlenmeyer portion, as well as fritted disc to aid in filtration. This design eliminates the need for the clamping device, stopper and base.
This item is used but is in great condition with no chips or cracks.
