Restek® Pack in a Box Kit
Restek’s Pack in a Box kit is a complete
column-packing system. Everything you
need to pack your own analytical HPLC
columns is included: pump, 20 mL reser-
voir, column hardware (150 x 4.6mm, 316
stainless steel tubing with end-fittings,
frits, nuts, and ferrules for two complete,
empty columns), and system control soft-
ware (computer not included). Detailed
packing instructions and a DVD are also
included. The packing pump is electric, so
no pressurized air is required. AC input
requirement: 85–265 VAC. 10,000 psi
maximum pressure.
Bio-Safe Column System (PEEK)
• Completely biocompatible.
• 100% metal free.

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.
1/ 4 " 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.
