Cleaning the extraction cone
Required materials
•
Chemical-resistant, powder-free gloves.
•
Appropriately sized glass vessel in which to completely immerse the
extraction cone when cleaning. Use only glassware not previously
cleaned with surfactants.
•
HPLC-grade (or better) methanol.
•
HPLC-grade (or better) water.
•
Formic acid.
•
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.
Warning:
To avoid personal contamination with biohazards or
toxic materials, and to avoid spreading contamination to
uncontaminated surfaces, wear clean, chemical-resistant,
powder-free gloves when working with the extraction cone.
Warning:
To avoid injury, work with extreme care. Use a fume
hood, and suitable protective equipment. Formic acid is
extremely corrosive and toxic.
Notice:
To avoid damaging the fragile extraction cone, do not
place it on its tip; instead, place it on its flanged base.
