Maxe Geba Flex-tube kit


GeBAflex Tube Dialysis and Buffer Exchange Kits are the best-selling products in a decade for protein and nucleic acid dialysis, purification, or buffer exchange applications. GeBAflex Tube Dialysis and Buffer Exchange Kits include a specially designed single-use plastic tube that has a built-in permeable membrane that allows for salt migration. The high quality of the membrane allows unsurpassed recovery of 98% of pure samples.

The patented membrane is free of contaminating nucleic acids, heavy metals and treated with EDTA. The kits work in an easy-to-handle way by pipetting the sample into the tube and performing dialysis while the tubes are floating in the buffer. A floating rack is even included for added comfort of use. Multiple samples can be processed at the same time, allowing for high-throughput applications. No special equipment or syringes are required.
