An automated solvent dispensing workstation was developed for accurate solution preparation in industrial R&D labs. This system meets or exceeds manual preparation accuracy for volumes from 10 mL to 4.5 L.

Area of Science:

  • Analytical Chemistry
  • Laboratory Automation
  • Process Engineering

Background:

  • Manual preparation of solutions and mobile phases in industrial R&D is time-consuming and prone to variability.
  • Existing methods may not consistently meet stringent precision and accuracy requirements for all applications.
  • There is a need for automated systems that enhance efficiency, safety, and compliance in laboratory workflows.

Purpose of the Study:

  • To develop and implement an automated solvent dispensing workstation for industrial R&D.
  • To ensure the automated system meets or exceeds the precision and accuracy of manual preparation methods.
  • To address business, safety, and compliance requirements in solution preparation.

Main Methods:

  • Design and construction of an automated workstation for solvent dispensing.
