With GINTRONIC GraviTest 9000-Series, GINTRONIC AG has taken the gravimetric determination of the water vapor transmission rate of polymeric films and other sheet materials to the next level. GraviTest offers simple specimen preparation, user-friendly GraviCommander PC software and the complete automation of the measuring process.
User friendly PC software: The results of the measurement and the corresponding atmospheric pressure will be represented in a chart and stored by the PC software. Thus, each measurement result, together with the parameters of each individual sample are always retrievable and comprehensible. The following errors can thereby be excluded: miss-measurement caused by erroneous reading off of the scales, incorrect record of the measurement results, and missing of the weighing interval. The software is able to export all data easily to Excel®. The software comes complete with multiple Excel ® modules. These modules are used for various standards when the results are reported in different values such as perms, permeability, permeability coefficient or a SD-value.
Changeable tray: All GINTRONIC GraviTest are equipped with our changeable tray technology. This allows the adaption of the instrument to various sample holders, like sorption, 28,3 and 30 cm2 cups and blister holders (ASTM D7709-12 / USP 671). For this GINTRONIC AG offers a wide range of kits, to adapt the instrument perfectly to the needs of the customer and to the different standards.
The flexibility of the system has
nearly no boundaries. Wet cup, dry
cup or multilayer processes can
be carried out trouble-free, at different climate conditions and air
speeds, without any modifications.
The results of the measurement
and the corresponding atmosphe-
ric pressure will be represented in
a chart and stored by the PC soft-
ware. Thus, each measurement result, together with the parameters
of each individual sample are al-
ways retrievable and comprehensi-
ble.
The following errors can there-
by be excluded: miss-measurement
caused by erroneous reading off of
the scales, incorrect record of the
measurement results, and missing
of the weighing interval. The soft-
ware is able to export all data easily
to Excel®. The software comes com-
plete with multiple Excel®
modules. These modules are used for various
standards when the results are re-
ported in different values such as
perms, permeability, permeability
coefficient or a SD-value.
Durch den weiten Feuchtebereich ist auch die Bestimmung der SD-Wert Kurve von SD-Wert-veränderlichen Membranen an mehreren Punkten leicht möglich.
The exterior of the internal cham- ber of GraviTest is heated. This pre- vents condensation at high tempe- rature and humidity and protects the instrument, also at in case of short power failures. This technique was introduced by GINTRONIC al- ready in 2012.
