Product Description
Pipetting a sample directly onto a gel bed can gouge the surface and spoil band shape. This sample diffusion disc protects the top of the bed so manually applied samples spread evenly, helping preserve resolution in low-pressure separations. It is a simple accessory with a real impact on results.
This listing is for Kimble catalog number 420404-2500: FLEX-COLUMN Sample Diffusion Disc, 2.5. The disc has a transparent acrylic ring sealed to a 20 micron HDPE disc. A crossbar across the top of the ring makes it easy to lift out of the column. Discs fit FLEX-COLUMN columns with 1.0, 1.5 or 2.5 cm inside diameters. Order it from LIGHT LABS and keep your lab stocked with genuine DWK Life Sciences products.
