Cleaning the Sample Cylinder
1. Preheat the drying oven to 110 °C.
2. Clean the sample cylinder using a ratio of 5 grams of detergent (Alconox or a similar product) per
500ml of warm water. Fill the bowl of the ultrasonic unit with enough water to cover the sample
cylinder. Ensure that the detergent is dissolved before placing the sample cylinder into the water.
3. Submerge the sample cylinder in the bath and fill a long-stemmed pipette with water. Pipe the
water into the cylinder to remove all air.
4. Turn on the ultrasonic bath and allow it to run for approximately 30 minutes.
5. Using latex gloves, remove the sample cylinder from the bowl. Fill a pipette with hot water and
then pipe the water into the cylinder to rinse it. Repeat this process several times.
