A. INTRODUCTION:
Essential Life Solutions
Ltd Media-Flex® columns are suited for semi-preparative and prepara-
tive pressure chromatography. Available with 6 diameters (5, 10, 15, 20, 25, and 50 mm) and 3
maximum bed lengths (120, 260, 500 mm). The pressure stability depends on the column diameter
(5mm: 90 bar/1300 psi; 10 mm: 80 bar/ 1160 psi; 15 mm: 70 bar/1016 psi; 15mm: 70/ 1016 psi;
20 mm: 60 bar/870 psi; 25 mm: 50 bar/ 725 psi; 50 mm: 25 bar/ 362 psi). The height-adjustable
end piston allows variation of the bed length for 60 or 120 mm, respectively. A dead volume at the
column inlet can be eliminated without opening the column.
