GINTRONIC AG is setting his focus on highest quality, simplest operation and complete customer satisfaction.
The team includes a handful of well-chosen material, chip and parts suppliers. They have the same sporting spirit and the same ideas about impeccable quality that GINTRONIC takes for granted.
GINTRONIC developed
and constructs special electronic and electromechanical devices.
GraviTest 9000 Serie
With GINTRONIC GraviTest 9000 - Series, GINTRONIC AG has taken
the gravimetric determination of the water vapour 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.
This, in combination with the accurate and robust balance, allows
for high precision gravimetric measurement of water vapour
permeability, with a minimum of expenditure of time on the user’s
side, the gravimetric method becomes mere child’s play.
Through the Windows® based PC software, all measurement
parameters of the samples, such as temperature, relative humidity
of the air, air speed as well as the weighing interval, are predefined
and then adjusted automatically by the instrument after the start up
of the measuring process. As soon as the measuring conditions
correspond to the specified tolerances the specimen holders can be
inserted into GraviTest and the measuring process can be started.
Re-sealable specimen holders with an integrated seal and wax
sealing are available and can be used without any modifications on
the instrument. Assembling the samples into the 6 specimen holders
takes a matter of minutes.
The flexibility of the system has nearly no boundaries. Wet cup, dry
cup or multi-layer processes can be carried out trouble-free, at
different climate conditions and air speeds, without any
modifications.

With a maximum load of 250g @0,01mg resolution and 320g or
420g @ 0,1mg resolution GINTRONIC AG uses high capacity
balances.
This means for the user no surprises due to overload of the balance.
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: missmeasurement
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.
Due to the wide humidity range also the determination of the SDvalue
curve of SD-value-variable membranes at multiple points is
easily possible.
The measuring chamber is heated from the outside if required.
This prevents condensation at high temperature and humidity and
protects the instrument, also at in case of short power failures.
This technique was introduced by GINTRONIC already in 2012.
GINTRONIC offers 30 and 50cm2 inverted cups for ASTM E96BW.
Several international standards (e.g. EN 1931and ASTM E96) specify
that the sealing of the materials to the measuring cups has to be
done by wax. Also, there are several materials which can only be
tightened by wax sealing.
GINTRONIC has for this an optional user-friendly wax sealing
system.
The system can be extended up to 50 mm sample thickness, by
using the GINTRONIC distance rings for wax cups.
The 50mm version of GINTRONIC GraviTest can test samples with a
thickness up to 50mm.
The use of a special distance sensor makes sure that the samples
are exposed to the correct air velocity depending on their thickness.
A maximum flexible wax kit up to 50mm with GINTRONIC distance
rings is available, which makes also the preparation of thick samples
user friendly and practicable.
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 7709-12 / USP 671).
For this GINTRONIC offers a wide range of kits, to adapt the
instrument perfectly to the needs of the customer and to the
different standards.
Customised kits possible.
With the optional GINTRONIC MultiCommander technology it is
possible to define up to 4 sample groups which can be measured
independently in terms of time.
This reduces no-load running to a minimum and offers maximum flexibility and
maximum sample throughput to the customer.
With a width of 52cm the instrument design was kept intentionally
compact providing a capacity of up to 12 sample places 50cm2 and
up to 15 sample places 28,3/30cm2 using the GINTRONIC Slimline
technology.
This safes valuable space in the laboratory.
GINTRONIC GraviTest fully complies with ASTM D7709-12 and USP
671. GINTRONIC provides a set of special sample holders for
blisters and small containers. Up to 13 sample holders are possible.
With the stainless steel cup kit you can measure the WVTR using
corrosive salt solutions. This is very important the the determination
of special points of the SD-value curve of SD-value-variable
membranes.
In the new development of the GraviTest 9000 series, following the
successful predecessor model 6300, even more emphasis was
placed on maximum flexibility. Thus, it is possible to change the
specimen grips in the simplest way, if required. This allows the use
of different sample holders such as standard holders with 28.3 or 30
cm², blister holders or sorbent cups.
Customized specimen holders are also possible, we will be happy to
check your requirements.
The instrument design has been deliberately kept compact with a
width of only 52cm to save valuable laboratory space. The saturator
is integrated in the instrument and does not require any additional
space on the bench. Condensation is prevented by the actively
heated measuring chamber housing. The transparent front with
illuminated measuring chamber also allows visual monitoring.
The measuring capacity with 50cm² standard cups was increased
from 6 to 9 samples.
The sophisticated basic concept of the device offers scope for
customer-specific adaptations. Contact us, we will be happy to help
you.
In a lively process of close cooperation, you will receive convincing solutions to your problems. In GINTRONIC you have a partner who listens, thinks along, thinks ahead and for whom the finished result counts, as it does for you.
Quality begins in the mind. In planning and design, in development and construction, in layout and programming. At GINTRONIC you have a single contact person who knows what you are talking about. And he is personally present during commissioning, instruction or support.
