The new Systech 8700 oxygen-transmission-rate (OTR) analyzer cuts oxygen measurement time in half for barrier PET bottles, the co. says. Measuring oxygen transmission through bottle walls remains the benchmark test for barrier equipment qualification. The Systech 8700 measures OTR in 12 hr instead of the conventional 24-hr cycle. The system measures up to 11 samples with a single instrument, yet requires only half the space of other instruments on the market. Measurement capacity can be increased by operating several devices simultaneously. Another special feature of the analyzer is its use of nitrogen, an inexpensive carrier gas, as opposed to a nitrogen/hydrogen mix. The co. also claims that maintenance costs are lower because the instrument sensor is automatically protected from exposure to high oxygen levels.
