Using Filler Rods
Filler rods of two different sizes are included in the accessory kit. Insert them as described below.
1. Clean your sample tube, balance tube, and filler rods; label your sample and balance tubes.
2. Hold the balance tube horizontally, and carefully slide the longer filler rod into the tube.
3. Prepare your sample and place it into the sample tube; insert the shorter filler rod into the sample
tube.
If you are using bulbous sample tubes, use the same size filler rod as used in the balance tube.
For subsequent samples of the same material, you may simply use the same mass of
sample that was used for the initial sample so that the original bead quantity may be
left undisturbed on the balance port.
Do not hold the rod vertically and drop the rod into the tube; this may break the tube.
