What is the difference between AQ™ brand and low cost syringe filter brands?

Reference Number: AA-01021 Created: 10/10/2012 02:58 PM Last Updated: 02/02/2018 11:51 AM

AQ™ syringe filters are made to a higher standard of quality such as extractables, adsorption, flow design and have a 3 piece leak proof plastic device. AQ™  filters are supplied with CofA for HPLC and Dissolution testing. They cost more but bring a "Consistency Insurance". These filters have bright colored rings for ease of identification. For LCMS or critical applications, these filters should always be used.

General low cost filters are acceptable quality for non-regulated labs but often do not have a CofA. They cost less but bring less value. They are simple basic filters and the imprinting is often one color not color coded and not ultra-sonically welded at the seams. These filters are adequate for HPLC sample filtration in non-regulated laboratories.
