Glove boxes and inert atmosphere systems are widely used in battery research, advanced materials, chemical synthesis, and semiconductor laboratories. Vacuum pumps in these systems are mainly responsible for initial evacuation, atmosphere exchange, and pressure control, rather than achieving deep process vacuum. This article focuses on practical vacuum pump types actually used in glove box systems, explaining where each technology is applied and why.

Freeze drying (lyophilization) is a critical dehydration process widely used in pharmaceutical manufacturing, biotechnology, food R&D, and laboratory-scale research. Vacuum pumps play a decisive role in ensuring stable sublimation, consistent product quality, and reliable cycle times throughout the lyophilization process. This article explains how vacuum pumps function in freeze drying, what performance characteristics truly matter, and how to select the right vacuum solution for laboratory and industrial lyophilization systems.
