Redefining Cell Isolation

Introducing the MARS® Bar system, a breakthrough in in-flow Immunomagnetic cell isolation technology. Our systems offer positive and negative cell selection workflows, ensuring the separation of target cell subpopulations with exceptional purity, recovery, and viability.

MARS® is an open platform, accommodating various magnetic bead types, including those directly coated with antibodies tailored to your specific cell surface markers or molecules. Experience the simplicity and efficiency of cell isolation with MARS® – where innovation meets practicality, advancing research possibilities.

Built-in redundancy

Three independent modules ensure the functionality of a system, even in the unlikely event of a module clogging.

Matrix free Magnetic Technology

Our matrix-free magnetic column reduces dead volume and cell trapping for more efficient positive or negative cell enrichment and higher recovery.
