Spectrum Laboratories, Inc.: The New Spectra/Por(R) Tube-A-Lyzer(R)

Published: Apr 09, 2010

Rancho Dominguez, CA – Nov 20, 2009: Spectrum Laboratories, Inc. presents the Tube-A-Lyzer. It is a ready-to-use, gentle separation device that combines convenience and disposability with the efficiency of dynamic dialysis to significantly increase the mass transfer rate and reduce the overall dialysis from 1-2 days to 4-12 hours. This self-contained, disposable device incorporates a semi-permeable membrane tubing that separates the sample chamber from the surrounding flow-through buffer chamber. The dry Biotech Grade Cellulose Ester (CE) membrane tubing is available in 6 MWCOs and the membrane-defined sample chamber is available in 2 volume sizes. The sample port provides easy access for loading, recovering and in-process testing. The housing is designed to be a flow-through dialysate chamber that can be connected to a buffer source and a waste collection vessel, or for discharging directly to drain. Tube-A-Lyzer is non-pyrogenic and can be sterilized (25 kGy gamma irradiation).

Mounted onto the support rack of the KrosFlo® Research II Pump System, the Tube-A-Lyzer device (Spectrum Laboratories part no. ACR2-021-01N (110V) or ACR2-022-01N (220V)) can be operated as a single unit or in parallel when multiple units are combined using a coupling bracket (sold separately) into a multi-unit device. A second pump head can be mounted to the pump to operate two Tube-A-Lyzer units in parallel.
