PhasePrep II Solution Preparation---Solvent Mixing System

The foundation of analytical chemistry is accurate, documented solution preparation and solvent mixing. The PhasePrep II is a new instrument designed to document and prepare solutions and mix solvents for HPLC mobile phases, titrations, extractions etc.

Reliability, accuracy, and versatility is designed into the new PhasePrep II

• The proven, self-priming solvent pumps can handle virtually any solvent and can dispense a few drops or deliver solvent at a rate up to 500 ml/minute. As little as 10 ml or as much as six or seven liters of solution can be prepared in a few minutes.
• The integrated, industrial grade, touch screen computer has no hard disc drives, no external keyboard, no mouse.
• Up to 100 solution preparation or solvent mixing methods can be easily entered and recalled on the touch screen. For added security all methods and important system parameters are password protected. Up to 20 different operators can access the system through assigned passwords.
• A total of eight different pumps can be added to the PhasePrep II. Any of three solvents and a solute (or buffer) can be added to a solution or solvent mixture.
• The integrated, 8.2 kilogram capacity weighing module (Sartorius Mechatronics, Germany) measures the weight of the dispensed solvent to a resolution of 0.01 gram (~10 microliters).
• Each preparation is automatically labeled.
• Methods can be easily written for preparing solutions on a g/ml or a g/g basis. Solvent mixtures can be configured for either weight percent or volume percent of a two or three component mixture.
