Internal reducers
Valco’s patented internal reducer (IZR) allows smaller tubing to be used in valves
with fitting details for larger tubing, forming a positive leak-free seal with zero
dead volume. The small line from your system goes directly into the IZR and
the sample goes directly into the valve, without the short pieces of connecting
tubing required if a reducing union was used instead. (A reducing ferrule would
also work, but makes a seal of less integrity.) Once the fitting is installed, only
one wrench is required to remove and reinstall it.
A second version has a 2 micron stainless steel frit pressed into the end of the
liner, adding filtering capability. However, we suggest using these only as a final
or backup filter, with a standard filter (
see page 52
) as the primary filter. Because
IZRs have a much smaller surface area than the standard filter, they tend to plug
too often if used in a stand-alone capacity.

Internal reducers
for 360 µm tubing
Directly connect 360 µm tubing into a 1/32" Valco valve or fitting detail,
providing a positive leak-free seal with zero dead volume. The same patented
design as our larger internal reducers (below). Both versions have a stainless
steel body.
