Experiment-purpose electrodialyzers and diffusion dialyzers

These lab-scale electrodialyzers and diffusion dialysers can be used for testing to generate data that will be useful for scaling up to a full-size system.


These units are ideal for refining chitosan, taurine, carnitine, chitin, citric acid, glycerin, keratin, silk protein, ornithine, xylol, aspartame, anthocyanin, and other substances. These systems include a lab-scale electrodialyzers with a tank and pump rectifier. When fitted with an ion-exchange membrane, they make it easy to begin experimenting with electrodialysis. Two different models, DW-Lab and CH-0, are available.
