The Bill-Board set has been designed to simplify and expedite multiple, solid-phase syntheses. Up to 6 reactions can be conducted simultaneously in fritted glass reaction vessels. The Bill-Board equipment keeps the solid-phase reactions organized in a grid (for potential combinatorial reaction sequences). Also, the system simplifies the essential steps of solid-phase synthesis which involve repeated cycles of reactions and washings, followed by a final cleavage, product collection and solvent evaporation. The Bill-Boards can also be used for any procedures that require multiple filtrations (i. e. simultaneous silica gel chromatography). complete Set Consists of: 6 each: CG-1869-08 Glass Vessels 1 each: CG-1869-10 6 Position Top Plate 1 each: CG-1869-12 Drain Tray 1 each: CG-1869-14 Vial Collection Rack 6 each: CG-1869-50 4 Dram, 25 x 52mm Collection Vials.
