rods, then remove the sample tubes and filler rods from the unit.

7. Rinse the sample tubes and filler rods thoroughly with hot water. Rinse again with isopropyl
alcohol or acetone. If isopropyl alcohol or acetone is not available, deionized water may be
used.

the rack. Bake in a vacuum oven for two hours at 110 °C.
Samples tubes can also be cleaned with high purity acetone or isopropyl alcohol and
dried for about 10 minutes under heat. If using this method, continue with step 10.
