Precision Mobile Phase Preparation

PhasePrep is designed to document and prepare solutions and mix solvents for HPLC mobile phases, titrations, extractions, and more. Prepare samples gravimetrically rather than volumetrically for improved accuracy, increased safety, and reduced waste.

0.02% Accuracy

Gravimetric dispensing eliminates temperature-dependent volumetric errors for exceptional precision every time.

Improved Safety

Closed system design dramatically reduces or eliminates pouring, spillage, and exposure to harmful solvent vapors.

Automatic Documentation

Built-in label printing and complete audit trails ensure GMP compliance and full traceability.

Reduce Waste

Prepare exactly the amount you need - 135 ml or 653 ml as easily as one liter. Minimize solvent waste.

Save Time

Automated five-step workflow saves labor while increasing accuracy when preparing solutions with internal standards.

100 Methods

Store up to 100 different preparation methods for quick recall and consistent results.

Learn About Advantages

Simple Five-Step Workflow

PhasePrep saves labor while increasing accuracy when preparing solutions with internal standards:

  • Operator enters sample number and initials
  • Place sample bottle on balance - weight is recorded automatically
  • Add appropriate amount of solute when prompted
  • Computer calculates exact solvent amount - dispensed with 0.02% accuracy
  • Remove completed sample and affix printed label
