UPLC PEEK NUTS

Advanced Fitting Design. Smart-Fitting System.

When pressure approaches 5000 psi (350 bar), capillary lines have the tendency to pop-up when tightened by regular HPLC fittings. The advances, during the past few years, of ultra-high-pressure liquid chromatography makes reliable connections a challenging task, if used with finger-tight fitting design. 

Ultra High Pressure Fittings

• Strong stainless steel thread allows many more use-cycles than a one-piece PEEK design.
• Finger-tight installation. PEEK tip installs permanently and cannot be lost.
• Pressure rating up to 14,000 psi (1000 bar).
• One-size-fits-most applications, including columns, valves, and instrument ports.
• Break-resistant — when a normal column is accidentally dropped with the fitting in, the PEEK fitting usually breaks, leaving hard-to-remove pieces inside the column. Metal fitting can bend — but it won't break, and thus it can be simply replaced with another fitting, saving the expensive column.
• Improves heat transfer with the incoming capillary, when a column heater is used.
• PEEK and metal-capillary compatible.
• Special capillary tube gripping mechanism allows strong holding effect of the tube, even with very gentle tightening force.
