3.1.2 Cleaning the Caps
Use the following procedure to clean caps without filters.
1. Place caps into a clean 4-liter polyethylene container. Fill the
container three-quarters full with deionized water and cap.
2. For trace-level analyses, allow the caps to soak for a minimum of
24 hours in deionized water. This allows time for contaminants to
leach out.
3. Vigorously agitate the container for 30 seconds. Drain the water.
Repeat four times.
4. Refill the container to the top with deionized water and cap.
5. When you are ready to use a cap, use clean forceps to remove one
from the container. Shake off any excess water and install the cap in
the vial.
3.1.3 Cleaning the Filter Caps
Use the following procedure to clean caps with filters.
1. Place caps into a clean 4-liter polyethylene container. Fill the
container three-quarters full with deionized water and cap.
2. Vigorously agitate the container for 30 seconds. Drain the water.
3. Empty the caps onto a clean surface.
4. Using a clean syringe, force 50 mL of deionized water through the
filter frit from the top of the cap. Be sure not to dislodge the filter frit.
5. Place the rinsed caps into a clean 4-liter polyethylene container. Fill
the container three-quarters full with deionized water and cap.
6. Vigorously agitate the container for 30 seconds. Drain off the water.
Repeat four times.
7. Refill the container to the top with deionized water and cap.
8. When you are ready to use a cap, use forceps to remove a cap from
the container. Shake off any excess water and install the cap in the
vial.
For trace-level analyses, use caps without filters to avoid introducing
contaminants from the filter.
