Tapered-End CHROMAFLEX® / Flow Adapters CHROMAFLEX®
CHROMAFLEX® Flow Adapters 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.
Tapered-End CHROMAFLEX® Columns A modified version of our popular CHROMAFLEX® columns, these columns offer a higher performance level over traditional low pressure chromatography columns.
