Our #1 moisture analyzer for the plastics industry is the MA100C. 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 MA100C 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.
Pre-processing moisture in the material will have a direct effect on the physical properties of the material. Inadequate material drying can compromise material properties and result weaker impact resistance and lower tensile strength. Routinely monitoring the moisture content of the plastics both before and during production will yield higher quality parts.
Plastic molders that are processing ABS, nylon, polycarbonate, polyester, acetyl and other plastic resins need to know the dryness of their materials. Many of the automotive and medical customers are no longer accepting dew point monitoring of the moisture and air temperature coming out the dryer exhaust port as a reliable measure of material dryness. Any molder with a grain of salt knows that although you might purchase pellets in sealed bags stating they are dry and "ready to mold," that a pin hole in that bag will result in your material having a much greater moisture content. The only way to guarantee the material is dry it before molding. The Sartorius MA100C allows you to monitor your dryers effectiveness and know your materials true moisture content. This will insure ideal processing conditions that protect material performance properties and prevent appearance issues such as splay or silver streaks. Yielding the molded plastic parts your customers deserve and demand.
The Sartorius MA100C is very easy to set up, quick to use and provides repeatable moisture content results.
Sartorius MA100C Moisture Analyzer features a Ceramic IR heating element and readability to 0.001% or 0.0001 grams. The advantages of a Ceramic element is that it can rapidly attains the final temperature to ensure a uniform distribution of infrared rays over the entire sample surface, thus eliminating localized burning. Flexible for use in research, development and quality control and designed for years of use in demanding production environments.
The MA100C Moisture Analyzer can be purchase with an optional data printer integrated into the analyzer housing to meet ISO/GLP requirements.
Other Sartorius innovations found in the MA100C 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.

Special promo - we are now including 1000 extra moisture pans FREE with the purchase of a new MA100C only at Precision Weighing Balances. Sartorius sells 1 box of 50 pans for $39.00 - we are giving you 1000 pans with the purchase of a MA100C, so you save over $780 if you were to purchase these accessories direct from Sartorius.
We have the MA100C in stock. Buyer beware most companies selling balances online have ZERO inventory. We know people purchasing a moisture balance need it for an application yesterday so we stock it. It takes us over 2 months to get moisture balances from Sartorius since they are made in the Germany. So when you need a moisture balance buy from a company that has inventory or otherwise you will be waiting a long, long time. Nobody has more experience in building balances than Sartorius so why bother looking at an other brand? Nobody has been selling balances online longer than www.balances.com.

Don't let anyone tell you there is a long lead time for a MA100C since we are a stock Sartorius Distributor unlike the majority of web sites that offer balances and scale, but have ZERO inventory and most never even turned on a balance in their lifetime. Again we have the MA100C in stock and on the shelf. The MA100C is our most popular moisture balance for the plastics industry.

the interior of a sample, they are converted into heat energy, which
stimulates evaporation, thus drying the sample.

We always recommend people purchase moisture
pans that are oil free Aluminum and provide even
temperature across the pan. If you ever need
additional weighing
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
each test.
Glass
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.
