Someone internally at my company said they had, but I can't find any headline info on their website.

According to the Dionex website:

The UltiMate® 3000 Rapid Separation LC (RSLC) systems integrate unique hardware features for ultrafast separations and excellent resolution on columns with small particles. In addition, they are characterized by a maximum level of reliability and flexibility. For more product information on UltiMate 3000 UHPLC systems and solutions, visit

•SmartFlow® pulsation-free flows at flow rates up to 8 mL/min at pressures up to 15,000 psi (103.4 MPa).

Once the reliability and robustness of all components has reached a certain point and cost is reasonable, the manufacturers will only offer only UPLC systems. Dionex has increased the high pressure limit of all systems to 620 bars while decreasing the premium of the UPLC systems. In my opinion this will be the trend for most HPLC manufacturers...
