Diethylaminoethyl, DEAE

Weak Anion Exchangers, DEAE (Diethyl Amino Ethyl)

• Product Summary:

The proprietary polymerization technique ensures that the packing is not brittle and free of any leachable.
STYROS® DEAE provides Medium static and dynamic capacities to enable high throughput separation and purification during analytical and preparative runs.
STYROS® media are available in many different size columns both in PEEK and Stainless Steel.

 Key Features:

o Feature 1:
High protein capacity (measured with BSA)
85 mg/ml for STYROS®  DEAE
o Feature 2:
Although we have used pressures of up to 10,000 psi without irreversibly altering the structure of the beads, we recommend the following pressure limits:
3,000 psi for the XH series
3,000 psi for NB series
3,000 psi for the MB series
2,000 psi for Micro Trap columns
2,000 psi for Silica Capillary columns
o Feature 3:
No measurable shrinking and/or swelling due to highly cross-linked nature of the beads.
