HPLC Column Tubing
Restek® tubing is manufactured from fine,
chromatographic-grade 316 stainless steel.
It is corrosion resistant, ultrasonically
cleaned, and passivated. We polish the tub-
ing and promise a burr-free cut. You can
use this tubing immediately—there is no
need for additional treatment.

" HPLC Frits
We manufacture our frits from fine, chromatographic-grade
316 stainless steel, and we offer sizes to fit most column and
pore sizes. To choose the correct frit, check its pore size compat-
ibility with the particle size of the packing in the column. If the
packing has a smaller particle size than the pore size of the frit,
the packing can clog the frit.
