Vacuum Packaging is used to protect the food or contents from oxygen and preventing the evaporation of volatile components. Therefore, it requires the vacuum packaging materials have good oxygen barrier property. that means the oxygen transmission rate of vacuum packaging materials should be low. the materials should not easily let oxygen transmit through.
Labthink provides and manufactures professional oxygen transmission testing instruments based on different methods (equal pressure method or differential pressure method)
Equal Pressure Method - OX2/230 Oxygen Transmission Testing Instrument
This Instrument can be used for oxygen transmission testing for plat films or finished vacuum packages. This Instrument adopts Labthink’s latest exclusive patent design of three diffusion cells integrated in one instrument for individual or multiple tests, which improves test efficiency by 3 times. It can be easily connected with 9 satellite bases together to accomplish up to 30 tests at the same time.
OX2/230 Oxygen Transmission Testing Instrument is equipped with high precise sensor, have a huge test range of 0.01~65000cm3/m2·d and high resolution 0.001 cm3/m2·d.
This oxygen transmission testing instrument conforms to ISO 15105-2, ASTM D3985, ASTM F2622, ASTM F1307, ASTM F1927
Differential Pressure Method - VAC-V2 Gas (Oxygen) Transmission Testing Instrument
VAC-V2 Gas Transmission Testing instrument is right based on differential pressure method and can be used for oxygen transmission testing for vacuum packaging materials.
Besides gas transmission rate, this gas transmission testing instrument can also help to get solubility coefficient, diffusion coefficient and permeability coefficient of plastic films, composite films, high barrier materials, sheeting, and aluminum foils.
VAC-V2 Gas Transmission Testing Instrument conforms to ISO 15105-1, ISO 2556 and ASTM D1434
