Radium Disk
$6,764.33
CDS Empore 3291 Radium RAD Disks are high-performance solid phase extraction (SPE) tools designed for selective retention of Radium isotopes 226 and 228 using molecular recognition. Each disk is composed of Crown Ether bonded silica particles (12 µm) that capture the analyte and function as the counting medium in either liquid scintillation or radiometric analysis. This enables reduced turnaround time and lower operational costs in radiochemical testing workflows.
Available in:
47 mm (20 disks/pack, 3 packs/case)
90 mm (10 disks/pack, 3 packs/case)
