UltraShield direct connect precolumn filters provide economical protection from the harmful effects of sample and mobile phase particulates on modern UHPLC and other high resolution HPLC columns. UltraShield was engineered specifically for use in fast, high efficiency separations requiring high mobile phase velocities and ultra high pressure. UltraShield maintains the efficiency of these high performance columns assuring no loss of critical resolution. With its simple design, UltraShield installs in any analytical column in seconds and is leak tight to 15,000 PSI. Simply tighten the filter with a wrench until it is snug, followed by an additional 1/4 turn.
