Save a barrel of cash on this demo unit. If you are testing plastic, nylon or resins samples the MA100C is the moisture analyzer you need to determine if you have your dryers properly set. The MA100C moisture
balance meets the manufacturer specifications and is calibrated by factory trained
Sartorius technician prior to shipping to you. The balances has all the
original packing material and operation manual, but the box will show signs
that it was shipped around for before as a demonstrations unit. The balance
and weigh pan has some small scratches that shows cosmetically that the unit
is not brand new, but the balance will perform as a brand new unit. Sartorius
classifies this balance as DQE - Demo Quality Excellent. Demo balances
carry a limited 12 month manufacturer warranty while new unit have a 3 year
warranty.
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.
Other innovations include integration of the heat source into the chamber cover.
The motorized heating unit 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.
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. Review additional technical data on the Sartorius

Oh and if you want to call us for "what is my price"
or "can you quote me" again save
all of us time since the price online is rock bottom and not a penny less. In fact, all DQE/Used balances are subject to availability. We update
the used balance section every month. You can see a complete listing of the Demo/USED Balances at the bottom of this web page.

The top of the display shows the drying program and test function in process.
Infrared
rays 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.

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.
"We
