Size/Concentration Standards

Fluid Imaging Custom bead mixes, containing 3 different sized beads at a known concentration for size and concentration calibration. Each bottle has a Certificate of Analysis (CofA) indicating the beads are NIST-traceable for sizing and count-certified  for concentration. The beads are in a "neutrally-buoyant" aqueous carrier liquid, making them optimal for use in a dynamic imaging particle analyzer.

Verification Beads for 10X and 20X Objectives - $175.00
(10ml bottle)
NIST Traceable Sizes 5, 10, 25µm at approximately
100K, 75K and 15K particles/ml (see CofA for exact concentrations)
Verification Beads for 4X and 10X Objectives - $175.00
(10ml bottle)
NIST Traceable Sizes 15, 25, 50µm at approximately
10K, 5K and 1.7K particles/ml (see CofA for exact concentrations)

Concentration Standards

NIST-Traceable calibrated microspheres in solution at calibrated concentration for verification of concentration measurements.

 10µm Beads at 3,000/ml (25 ml bottle) - $60.00
 20µm Beads at 3,000/ml (25 ml bottle) - $60.00
 50µm Beads at 3,000/ml (25 ml bottle) - $60.00

Fluorescent Beads

These beads are used to verify that FlowCAM® is correctly triggering on fluorescence signals (for systems equipped with this capability).
