Whatman Cellulose DE-52 纤维素 DE-52现货

M23 dry fibrous carboxymethyl cellulose
Uniformly substituted fibrous media allowing very fast flow rates, especially after fines removal; exhibits high binding for proteins ａnd biopolymers bearing positive charges.
CM32 dry microgranular carboxymethyl cellulose
High-capacity medium for proteins, hormones, polypeptides, ａnd other biopolymers bearing low to high positive charges; excellent resolution with good column flow rates. Requires precycling to restore swelling. Equivalent after swelling to CM52.
CM52 preswollen microgranular carboxymethyl cellulose
High-capacity medium for proteins, hormones, polypeptides, ａnd other biopolymers bearing low to high positive charges; excellent resolution with good column flow rates.
P11 dry fibrous cellulose phosphate
Dry fiber. Recommended for column separations.
EXPRESS-ION High Flow Rate Ion Exchange Media are described separately.
Ion Exchange Celluloses are also available in paper format.
