EMERGING APPLICATIONS:

ISOTOPE

SYNTHESIS >>

Much of the equipment created for the synthesis of F18, N13, O15, and C11 utilizes off-the-shelf components from our product lines.

BEAD FLOW

CYTOMETRY >>

Many of our standard products for liquid handling are ideal off-the-shelf components for automated sample preparation, handling, mixing, and delivery.

PROTEOMICS

RESEARCH >>

VICI valves, tubing, and fittings can radically reduce the time required for the incredibly complex separations involved in proteomics

research.

LIQUID

BRACHYTHERAPY >>

Valco Instruments is partnering with The Gabriel Institute and IsoTherapeutics Group, LLC to pursue pioneering work in the direct administration of therapeutic isotopes into tumors.
