Molded polycarbonate carboy with sanitary closure system instead of threaded neck may be closed with a True Union or sanitary band clamp and end cap. This creates a virtually leakproof shipping container. With an operating range of -85°C to +121°C, carboy is well suited for hot or cold environments, eliminating problems with threaded closure systems due to temperature variations.
