Quick and efficient desalting, buffer exchange, removal of dyes and small molecules from proteins greater than 25 kD with minimal dilution. Purified proteins are eluted into pure, deionized water. (Caution! Some proteins may precipitate in pure water with low ionic strength!) The gel bed has a volume of 0.8 ml. Samples with a volume of between 10 and 100 µl can be processed. Optimal purification and recovery is obtained with a sample volume of 50 µl
