the reservoir of the ultrasonic unit with enough water to cover the sample tubes and filler

into the water. If too much detergent is used, it may be difficult to rinse from the sample
tubes.

cleaning unit. Turn on the ultrasonic cleaning unit. Leave the glassware in the unit until
the walls of the tubes are free of sample residue.

6. Clean the interior of the sample tubes with the brush supplied in the accessories kit.
7. Rinse the sample tubes thoroughly with hot water, then with isopropyl alcohol or acetone.
If isopropyl alcohol or acetone is not available, deionized water may be used to rinse
the sample tubes.
