Application area
Gentle desalination, purification and concentration of sensitive biological materials, such as sera, plant extracts, cell hydrolysates
Product specification
Seamlessly manufactured dialysing tubing made of purest cellulose hydrate membrane material. Larger number density of pores and lower wall thickness increase dialysing speed by 20 % and more compared to standard qualities without loss of mechanical stability. Mean pore size 25 Å, nominal cut-off at MW 15 kDalton. Laboratory-suitable supply length of 3 and 15 m/roll, graded flat widths between 4 mm and 148 mm.
Technical specification
Diffusion permeability for salts: 4.2 x 10-4 cm x s-1; (pressureless continuous-flow cell; 0.1 % aqueous urea solution at +20 °C)
Mechanical permeability: 3.1 x 10-5 cm x s-1 bar-1; (stirring cell 0.1 bar; water at +20 °C)
Retention against dextran: 63 % (1 % dextran solution, MW 10,000; 0.1 bar)
