Density gradient-based islet separation using computer-controlled LAMBDA pumps

Computer controlled programmable HIFLOW peristaltic pumps used to generate density gradients in automated purification of isolated human islets.

Islet and non-islet tissue have specific and different densities; the differences in densities has been utilized in islet separation and purification. PNet software controlled, HIFLOW peristaltic pump-made density gradients are created to separate the islets from unwanted tissues.

Programming the HIFLOW peristaltic pumps with PNet software

PNet software controlled pumps need instructions for dosing high and low density solutions at specific time points. This precise dosing ensures consistent gradient production.
