Product specification

High-tech dialysing tubing made of regenerated cellulose for overall biological research, seamlessly manufactured, in rolls, made of clear highly pure and molecular-porous membrane material, absolutely free of traces of heavy metal and sulfur compounds, extremely low protein absorption especially in a weakly acetous environment, narrow cut-off ranges. Stabilized for storage with glycerol. For low and high-molecular systems with correspondingly defined cut-offs.

Because of its glycerol content required for storage stability, THOMAPOR^®-dialysing tubing should be washed with water or diluted acetic acid before use. For storage of unused dialysing tubing air-tight containers are recommended which should be stored in the refrigerator. The tubing can be used in the pH range of 2 to 12 and at temperatures of +4 to +121 °C. The mentioned cut-offs are recommended values. In case of uncertainty the suitability of a given dialysing tubing has to be determined in preliminary tests, as the effective pore sizes of the cellulose membrane material depend on several external physico-chemical factors, e.g. the buffer composition.
