From the inventors of linear taper unions, the most relaible union is now paired with the most popular deactivation
Unions accept columns from 0.25mm to 0.53mm bore, even if imperfectly cut (column OD 0.30mm to 0.72mm)
With less than 1/2 the restriction to flow of other unions -- ZERO restriction fro 0.25mm -- Pres2fit unions induce less turbulence so peaks are sharper
Use for pesticides, sulfur compounds, semi-volitile organics, etc. where sensitive, trace compounds are sought
The chamfered openings make column insertion a breeze and reduces the risk of chipping or tearing
