Moisture tester for the plastics industry. Moisture in plastics processing is a key deciding quality factor and although the Karl Fischer method was the accepted test for determining dryness of materials in the molded plastics industry the MA100 is becoming the new method. Karl Fischer titration is a titration method in analytical chemistry that uses coulometric or volumetric titration to determine trace amounts of water in a sample. Karl Fischer is complicated to use compared to the Sartorius MA100. Also, Karl Fischer uses iodine and requires hazardous waste disposal and other safety issues.
Sartorius MA100H moisture analyzer features a halogen lamp and is suited for applications that require accelerated temperature regulation during sample drying. (Note almost all the Sartorius Moisture Analyzers we sell are with the Ceramic IR heating element and not the halogen lamp so review the MA100C before you make your final selection). Whether you choose halogen or ceramic both heating sources use infrared rays to penetrate the sample without being impeded. Having reached the interior of a sample, they are converted into heat energy, which stimulates evaporation, thus drying the sample.
The MA100 moisture balance featuring the ultimate in measuring accuracy and functionality. With the accuracy of an analytical balance, the moisture meter MA 100 delivers exact results within minutes and excellent reproducibility. On top of this, its extensive functions offer a high level of flexibility to meet frequently changing requirements on the parameters of different types of samples or on the sequence of analysis.
The MA100H moisture analyzer includes an integrated motorized heating unit that opens and shuts at the touch of a key eliminating the need to use a hood (models designed with a hood include A&D MX-50/MF-50 moisture balance, the Mettler Toledo HB43, Ohaus MB35/MB45 moisture analyzer, Sartorius MA45 to name a few). This motorized system minimizes handling of the sample, speeding up the process and thereby preventing predrying during weigh-in. The motorized heat source also reduces exposure of the weighing mechanism to mechanical vibration.
Other Sartorius innovations found in the MA100H include "ASAP" mode: automatic (endpoint) searching/automatic programming for quick determination of the drying parameters and easy programming of a drying routine; Fast and easy control of the accuracy through DIN/ISO-compliant self-testing and self-calibrating capabilities thanks to the built-in calibration weight with reproTEST function; and more.

The MA100C is no longer sold in the USA by Sartorius. All information displayed herein is for people researching the specifications on the MA100C. If you need moisture pans or
glass fiber pads for your MA100C we sell these here.
If you need a moisture balance requiring resolution to 0.001% PLEASE GIVE US A CALL AT 978-521-7095 AND WE CAN OFFER YOU OTHER MODELS NOT SHOWN ON OUR SITE.
We always recommend people purchase moisture
pans that are oil free Aluminum and provide even
temperature across the pan. If you ever need
pans we sell them in bulk, 500 pans to a case.
Some people believe that they can reuse the pans but
this is never recommended. Although you might
clean off the pan the stains leave material from your
last test or even moisture when you attempted to clean
the pan. Others believe they can use a piece
of aluminum foil paper but this isn't always smooth
and creates crinkles and thus uneven drying.
Always, always, always use a new moisture pan for
fiber pads distribute the heat better, prevents
skinning over (this is when bubbles form).
The fiber pads are binder-free borosilicate glass
fiber and therefore contain no binders (no foreign
materials) or inert.
Slurry samples or when test times are long the sample
skins over, bubbles up or splatters when the moisture
testing is running, we recommend using filter pads
with the moisture pans.
For testing liquids the pads are a must. Place
the moisture pan and pad on the moisture balance,
adjust the setting time to zero so the Sartorius MA100
moisture analyzer is in auto mode and run the test
with no sample on the pad. Many times the fiber
pads can hold up to 2% moisture and this preps the
pan and fiber pad to be moisture free and only takes
typically 1 minute with the MA100 moisture analyzer.
Now with the dry filter pads if you are working with
a liquidity substance 70% water or more place the
sample with an eye dropper, syringe or pipette is
a spiral pattern and then cover with the filter pad.
For slurries and anything with bumps and chucks like
corn slurry we recommend using two pads making like
a sandwich (bottom pad - test sample - top pad).
Place the pan on the moisture balance and then place
one pad on your table and then using a syringe or
spoon apply the sample to the pad in a spiral pattern
and now cover with a second pad. Slightly squish
the sandwich you just made to break up any chucks
and the filter pads will absorb the moisture.
Now place the two pads with your sample sandwiched
in-between and run your test. You'll find more
consistent and repeatable rest using the two pads.

Warning - Moisture balancesshould not be used on any volatile organic sample with flash
points. Even a MSDS rating of 1. Samples with low flask
points like Acetaldehyde -38°C or MEK -4°C should not be used
with the Sartorius MA-100H Moisture Balance and maybe you should look
at Karl Fisher as an alternative.
Although you might presently perform analysis with an oven on these
samples the ovens typically have ventilation and a much larger cavity
than the typical moisture balance that operates on the principles of
TGA. In addition, with most moisture balances there is no ventilation
so all the fumes remain inside the hood of the moisture balance. We strongly recommend you consult with a safety
specialist always prior to using any moisture balances for your safety.
