Flow-Thru Macro Dialyzer

ElectroPrep Online

The Flow-Thru Macro Dialyzer is a new and unique product that is ideal for electro-elution, electro-dialysis, electro-concentration and electro-filtration of larger sample volumes (from 50 µl to 1 ml or more) and for protein crystalization.

The Flow-Thru Macro DIALYZER has an inlet and an outlet providing a flow-through system, which facilitates the continuous movement of the sample. Sample collection can be monitored through the use of an on-line detector, such as a photometer, conductivity meter or any other suitable equipment readily available in the laboratory. The Flow-Thru Fast DIALYZER can also be hooked to an HPLC sample loop for concentration of biological samples.

As shown in Figure 1, the sample from the sample reservoir (1) is pumped in continuous circulation through the sample chamber. The MWCO of membrane (a) is smaller than the molecular weight of the desired biomolecules. The MCWO membrane (b) is larger than the molecular weight of the desired biomolecules. The desired biomolecules will be collected in the concentration chamber (2) since membrane (c) also has a MWCO smaller than the desired biomolecules.

The setup in Figure 2 is similar. The sample from the sample reservoir (1) is pumped in continuous circulation through the sample chamber. In this instance, however, the concentration chamber (2) is also connected to a continuous on-line system with a sample detector such as an HPLC system. Therefore, the sample collected in the concentration chamber can be periodically measured and analyzed. Flow-Thru Fast DIALYZER includes chamber, two caps and two fittings.
