		High Pressure Gradient Controller Model 601
		Pump Unit Model 602
		Pump Unit Model 603
The FLOM Gradient Controller with a pump unit achieves precise flow control and accurate solvent composition. The flow volume, solvent composition, and flow rate can be programmed for precision control and automation 30 steps can be programmed with 20 files. Each gradient method can be programmed up to 30 steps with 30 files. The flow volume, solvent composition, and flow rate can be programmed during the solvent mixing process. Pressure limit can be set at the program phase and the mixing phase. The backlit LCD display shows flow rate and solvent composition as a graph for easy viewing.
		Low Pressure Gradient Controller Model 651
Capable of mixing 4 solvents. Equipped with the pump component of Dual Pump 203, flow rate and flow volume are controlled for precision gradient. Minimizes dead volume with pump's power valves. The cooling system prevents air bubbles from forming within the tube.
