OPTI-SOLV® Pre-Column Filters

Mini Filters
The OPTI-SOLV® Mini Filter provides low-impact filtering in a package no larger than a finger tight fitting. Use them to prolong the life of your analytical column, or before your mass spectrometer as a last line of defense against debris.

Perfect zero-dead-volume connections are obtained every time with our patented automatic tube stop depth adjustment. Unique depth-filtering elements allow for greater capacity with no band spreading or loss in performance. The efficient two-piece design needs no holder and threads into any 10-32 port.


Micro Filters
For your volume critical filtering needs, we offer the OPTI-SOLV® µ-Filter. Based on the same design that has made the Mini Filter a huge success, the µ-Filter cuts the internal volume to less than 200 µL, but retains the Mini Filter’s ease of use and functionality.
