Follow these steps to deactivate the glass insert in the 1061 Injector.
1
In a 10 mL glass graduated cylinder, add 0.5-1 mL of
dimethyldichlorosilane. Fill to 10 mL with isooctane, hexane or
toluene.
2
Cover the top of the graduated cylinder with aluminum foil and place
the cylinder in an ultrasonic bath. Sonicate for 30 sec to mix the
solution.
3
Add up to 2 inserts to the solution.
Note: Deactivate glass inserts only after they have been thoroughly
cleaned using the above procedure.
4
Sonicate the inserts in the cylinder for 10 min. Rinse the inserts 3
times with 10 mL isooctane, hexane or toluene. Each rinse should
include 2-3 min of sonication.
5
Add 10 mL of methanol and sonicate for 2-3 min. Decant the
methanol and repeat the methanol rinse step.
6
Decant the methanol. Transfer the deactivated inserts to a small
clean glass beaker. Cover the beaker with aluminum foil and bake at
200°C for 1 hour.

After the inserts cool to room temperature, store them in a clean
screw cap glass vial or the original packaging.
