• Dual piston mechanism for pulse-free operation
• Built-in low dead volume pulse dampener
• Self-flushing pump head for longer seal life
• Isocratic or high-pressure binary gradient
The Model 627 Preparative Pump delivers the accuracy and precision of a standard analytical pump at flow rates up to 100mL/min. Consistent flow rates and pressures minimize the potential for column damage. The 627 pump is available in 316 stainless steel or biocompatible PEEK. Buy one pump now and upgrade to a binary system later by purchasing a second pump and a high-pressure gradient kit.
