Since the bead amounts are based off of a mass ratio, we have provided a simple way to know how many beads you will need to obtain a certain mass. Our bead tables table is below, and a version complete with a bead calculator is available for download inOpenOffice Calc and Microsoft Excel formats.

Useful estimation - a full scoop with the bead spatula will hold about 50 microliters of 1mm or smaller beads, and you can often approximate the appropriate amount of beads by volume by using a 2:1 sample-to-bead volume ratio. Please know that scoop size may vary with different sized beads or because of human error, and the amount of beads required may change based on the protocol. If you find that measuring by volume causes inconsistency, then go back to measuring by mass.
