Cleaning the extraction cone
5-35
•
Ultrasonic bath.
•
Source of oil-free, inert gas (for example, nitrogen) for drying (air-drying
optional).
•
Wash bottle containing HPLC-grade (or better) 1:1 methanol/water.
•
Large beaker.
To clean the extraction cone
1. Immerse the extraction cone in the glass vessel containing 1:1
methanol/water.
Tip:
If the extraction cone is obviously contaminated, use 45:45:10
methanol/water/formic acid.
2. Place the vessel in the ultrasonic bath for 30 minutes.
Requirement:
If you used formic acid in the cleaning solution, do as
follows:
•
Rinse the extraction cone by immersing it in a glass vessel
containing water and then placing the vessel in the ultrasonic bath
for 20 minutes.
•
Remove any residual water from the extraction cone by immersing
it in a glass vessel containing methanol and then placing the vessel
in the ultrasonic bath for 10 minutes.
Warning:
The extraction cone can be contaminated with
biohazardous and/or toxic materials. Always wear
chemical-resistant, powder-free gloves while performing this
procedure.
Warning:
Formic acid is extremely corrosive and toxic. Work with
extreme care, use a fume hood and suitable protective equipment.
Caution:
The extraction cone is fragile. Never place it on its tip; always
place it on its flanged base.
