Direct Connect Stainless Steel Inline Filter Simply screw the filter into the column inlet. The replaceable 0.5µm frit protects the column from particles generated from the sample, HPLC system seals, and injectors. Replace the frit when back pressure becomes high or you begin to see peak broadening.
Advantage™ SENTINEL™ Guards 1mm Direct Connect Guard Columns  • Fingertight Connections • Unique Design for ZDV Connection • Narrowbore ID • Disposable and Economical • Packed Bed Filled with Small Particles The Advantage™ SENTINEL™ Guard Column sets the standard for low-impact, easy to use, pre-column protection. Designed for use with any HPLC column, the unique floating stem design automatically adjusts to any manufacturer's tube stop depth for a zero-dead-volume connection. No larger than a standard fitting, the SENTINEL™ requires no special connecting hardware or tools for installation. Special packing materials are selected to compliment the SENTINEL's narrowbore ID, providing effective protection for your analytical column, without influencing your chromatography. Fully disposable, simply switch out the SENTINEL™ as needed to maintain effective column protection. 
ADVFilter™ for In-line Protection The Advantage™ In-line Holder and Filters screw directly into your HPLC Column or Rheodybne Injection Valve.
