SureCount™ standards are suspensions of polymer microspheres intended for the validation and monitoring of particle counters and supporting sample preparation processes. SureCount™ standards are available in diameters of 3µm, 5µm, 10µm, and 15µm, and the diameters are traceable to NIST Standard Reference Materials. The standards are supplied as ~1 x 10⁶ microspheres/ml aqueous suspensions in 10ml volumes, and each bottle is provided with a Certificate of Traceability.

The Flow Cytometry Absolute Count Standard™ consists of highly uniform cell-sized microspheres labeled with a full spectrum dye, and provided at a known concentration. These beads fluoresce in FL1, FL2, and FL3, allowing them to be used as count standards in all three channels.

A test requires one drop (50μl) of particle suspension, which is equivalent to ~100,000 particles. Bangs Flow Cytometry Standards are 7-9μm in diameter (unless otherwise noted) to approximate the size of human lymphocytes.
