Internal reducer 1/8"x1/16", .50mm bore, 2 um frit, SS
*Now with new body material to eliminate galling and reduce thread friction!
Valco's 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. 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 Valco filter 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.
The most recent addition is an IZR for direct connection of 360 µm tubing to a 1/32" Valco valve or fitting detail. It is available in two versions - one with a stainless nut and ferrule and one with PEEK. Both have a stainless steel body.
