MOCON, Inc has recently ratified its presence in Tibet with the installation of permeation units.
The new facility constitutes the highest altitude installation by the firm. It is located 11,450 feet (3490 metres) above sea-level in Lhasa, Tibet. MOCON recently installed an OX-TRAN® 2/21 ML alongside a PERMATRAN-W® Model 3/33 MG Plus unit.
Both units were specifically designed to test permeation of either flat materials or finished packages/devices such as vials, pouches, bottles, blister cavities and syringes. However, in their current location at Lhasa, they will mainly be used to facilitate high barrier testing of packaging structures with either aluminium foil or metalised layers.
The installation constitutes part of an order received earlier in the year from China’s State Food & Drug Administration (SFDA). The order incorporated the supply of 20 provincial pharmaceutical testing centres with up-to-date oxygen and water vapour permeation units.
A closer look at the devices
The OX-TRAN 2/21 system features barometric compensation which is designed to normalise the test results to sea level. This ensures globally uniform test results regardless of the location, altitude, or weather conditions. In addition the device harnesses a patented cuolometric sensor (COULOX®) to detect oxygen transmission, indeed it even offers parts-per-billion sensitivity despite the presence of water vapour.
The PERMATRAN-W® Model MG 3/33 Plus unit offers automatic relative humidity (RH) capability. MOCON promises simple to use new software which will achieve accurate and precise relative humidity conditions.
