VICI’s unique 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 (ZDV) internal fitting. A small line from your system goes directly into the IZR and the sample goes directly into the port, without the short pieces of connecting tubing normally required when a reducing union is used. Once the fitting is installed, only one wrench is required to remove and reinstall it.
This IZR connects 1/32” OD tubing with 0.25 mm bore to a 1/16” ZDV port. The liner is made of stainless steel, and the body is made of a special alloy that eliminates galling and reduces thread friction.
When a tight seal is required, an IZR provides a much higher integrity seal than a typical reducing ferrule. Another version of the IZR is available with a 2 µm stainless steel frit pressed into the end of the liner, adding filtering capacity. However, we recommend using these only as a final or backup filter, with a standard filter as the primary filter.
