REACTION FLASKS flat bottom, wide neck with flat flange

**: The range of wide neck reaction flasks which are listed here are all interchangeable with the single socket and multi-socket flange lids which appear below. The accessibility feature of these wide neck vessels facilitate the removal of solid and glutinous materials.
Please note: Our range incorporates reaction vessels designed for vacuum operation, that come with a centred circular ‘groove’ on the face of the flange. The ‘grooved’ flange will require the Quick Release Clamp (QRCRV 100 listed below) and not the traditional ‘JC: F‘ series clamps. The groove accomodates the O-ring series below. These ‘grooved flange’ reaction vessels are denoted by the catalogue number, RBF: LFG

Available sizes: 10L 10000ml 20L 20000ml
