A new low-cost instrument is said to quickly and accurately verify the shelf-life of bottles containing carbonated beverages. It is suitable for use by carbonated soft-drink and beer producers and their bottle suppliers. Developed by Mocon, Inc., Minneapolis, new Permatran-C Model 10 measures the carbon dioxide transmission in plastic bottles from 250 cc to 2.5 liters. This non-destructive test takes as little as 3 hr. Bottlers and bottle makers currently rely on a variety of lengthy calculation methods to determine shelf-life. The Model 10 graphically displays projected shelf-life based on user-specified CO2 loss limit. The unit’s internal battery allows it to be placed in an environmental chamber for temperature profiling, and its portability enables its use in areas away from the lab. QuickStart software is said to allow for simple pushbutton operation, suiting it to QC use. Data can be downloaded to a PC or a printer.
