Labtron LGF-B11 Glass Fermenter features a 10 L working volume and a double-jacketed borosilicate glass vessel for controlled mammalian cell culture. Its top-driven mechanical agitation with a low-shear marine impeller operates at 30–300 rpm to support gentle and uniform mixing. A Siemens PLC with a 10.4-inch touchscreen manages pH, dissolved oxygen, temperature, and gas flow. Four-gas control supports regulated aeration and culture conditions.
