KONTES* FLEX-COLUMN* Accessories

Flow adapters allow easy adjustment of the column bed volume. Flow adapters are available for 1.0, 1.5 and 2.5 cm ID columns. Significantly improve column performance by protecting the gel bed from disruption during sample loading and by eliminating any dead volume above the gel bed. Flow adapters improve chromatogram resolution by delivering the sample and buffer directly to the top of the gel bed. They are also recommended when using buffer gradients or when the columns are connected to a low pressure pump system. Flow adapters consist of 1/16 in. OD PTFE tubing, a polyacetal body, a Viton* O-ring seal and a 20 micron porosity HDPE bed support. One replacement bed support is supplied with each flow adapter. Functional length 14 cm. For 1/16 in. OD polypropylene ferrule, see catalog no. 475-22486. For 10 feet of 1/16 in. OD x 0.038 in. ID, PTFE tubing, see catalog no. 475-22468.
