Learn SOP for vacuum pump in QC lab including operation, calibration, and cleaning for safe and efficient mobile phase filtration.
Introduction
In pharmaceutical quality control laboratories, filtration of mobile phase is a critical step to ensure particle-free solvents for techniques like HPLC. The vacuum pump plays a vital role in this process by creating suction for efficient filtration.
A properly defined SOP for vacuum pump operation, calibration, and cleaning ensures system efficiency, prevents contamination, and extends equipment life. This guide provides a structured and GMP-compliant procedure for handling vacuum pumps used in laboratory filtration processes.
Definition
Vacuum pump in laboratory is a device used to create negative pressure (vacuum) to assist in filtration, drying, or degassing processes, especially for mobile phase preparation in analytical testing.
