A Vertical Deep Freezer (Upright Deep Freezer) is a laboratory refrigeration equipment used for long-term storage of biological samples, chemicals, vaccines, plasma, and reagents at very low temperatures. It has a vertical cabinet with shelves or drawers, making it easier to organize and access samples compared to chest freezers.
