KONTES* CHROMAFLEX* Standard and Jacketed Accessories

Flow adapters improve chromatogram resolution by delivering the sample and buffer directly to the top of the gel bed. This protects the gel bed from disruption during sample loading and eliminates any dead volume above the gel bed. Flow adapters are recommended when using buffer gradients, during reverse flow applications and for high resolution gravity flow separations. Each flow adapter is supplied with a 20 µm porosity HDPE bed support, TFE/propylene O-ring seal, stainless steel adjusting rod, PTFE body and five feet (1.5 meters) of PTFE tubing. Use of aggressive organic solvents requires accessory PTFE bed supports and Kalrez* O-rings.
CHROMAFLEX packing reservoirs are ideal for packing gel slurries into columns. Each packing reservoir is designed for easy mounting on all CHROMAFLEX columns. The capacities are matched to take the amount of gel slurry required to pack the longest column. They may also be used as a buffer reservoir for gravity flow chromatography.
