Stainless Steel Frits
Upchurch Scientific
®
316 Analytical-scale Stainless Steel Frits are
available in 0.5 µmor 2 µmporosity—themost common HPLC fltration
ratings. Each frit includes a PCTFE or PEEK
™
polymer sealing ring.
Many of the frits shown have the common 0.250” (0.64 cm) and
0.254” (0.64 cm) ODs, which allow them to be used in the precolumn
and inline flters found startingon page 160. Choose the larger diameter
faces and/or larger porosity frits for faster fow rates. Choose frits with a
smaller diameter face and/or smaller porosity for applications sensitive
to extra fow path volume.

To Clean Or Not To Clean?
It is rarely worth the time and effort to clean frits, given the relatively low cost
of replacements. Furthermore, cleaning may leave some debris embedded in
the frit pores. If the washed frit is accidently returned to your instrument in a
reverse orientation, any remaining debris could be fushed out and deposited
further down the fuid path. If this frit is being used as a column head frit, the
debris may be washed directly onto the column bed.
