2.1.3 Extraction Cells and Rinse Cells
Extraction Cells
ASE 100 extraction cells are available in four sizes: 10 mL, 34 mL,
66 mL, and 100 mL. Interchangeable end caps screw onto each end of the
cell body. Each cell end cap contains a stainless steel frit and a seal.
During a run, the cell caps are compressed to form a tight seal between
the caps and the cell body.
An O-ring is installed on the outside of each cell cap. Teflon
®
O-rings
(P/N 049457, pkg. of 50) are standard. Viton
®
O-rings (P/N 056325, pkg.
of 50) are available for high temperature extractions, such as dioxins.
Note that only cell end caps with two knurled bands can be used with the
ASE 100 (see Figure 2-3).
Always tighten cell end caps by hand. Use of a wrench or other
tool can damage the cell, as well as the seal inside the cell cap.
If a Viton (black) O-ring is installed on the outside of the cell
cap, do not use acetone as the solvent for an extraction.
Cell end caps with two knurled bands can be installed in either
the ASE 100 or ASE 300 Accelerated Solvent Extractor.
However, end caps with one knurled band can only be used
with the ASE 300.
