FLEX-COLUMN® Sample Diffusion Discs
Sample diffusion discs protect the gel bed from being disrupted during sample application whenever a flow adapter is not used. A transparent acrylic ring is sealed to a 20µm porosity HDPE disc which protects the top of the gel bed when the sample is manually applied. A crossbar on the top of the acrylic ring permits easy removal of the sample diffusion disc from the column.
