Ohaus MB35 moisture analyzer features a maximum sample capacity of 35g, with a readability of 0.002 grams and repeatability to 0.02% for samples 10 grams or greater. The intuitive software establishes a simple user interface with simple 3 key navigation for easy setup. The MB35 offers a straight forward one step testing procedure. The moisture balance LCD display shows % moisture, actual weight, and actual temperature and test time.
Ohaus MB35 is Ohaus' mid range moisture balance offers limited features compared to the Ohaus MB45. Fast halogen element provides uniform infrared heating up to 160ºC in less than 1 minute. Analytical performance, with a readability of 2 mg, 0.05% moisture and 35 gram capacity. The Ohaus MB35 moisture analyzer display shows % moisture, time, temperature, weight and none of the advance features of the Ohaus MB45 moisture balance.
Operating the MB35 moisture analyzer is easy once the moisture balance parameters have been set, moisture determinations can be made very simply. There are three simple steps to perform:
Setting the drying temperature (50°C to 160°C in 5° increments.)
Setting the drying time (Automatic or Timed)
Gathering and preparing the sample. (Keep in mind the importance of attaining a proper composite sample that is homogeneous and the even distribution of the sample on the moisture pan. No mounds or piles.)
If you already own the Ohaus MB35 water content analyzer and you are looking for the consumable moisture pans you can purchase a box of 500 aluminum moisture pans for an extremely low price compared to what Ohaus charges for these moisture pans if you bought them from Ohaus Corporation directly.
We also sell moisture balance filter pads used to distribute the heat better, prevents skinning over (this is when bubbles form). Filter pads are really a must when testing samples containing large amounts of sugary substances since they tend to caramelize. To prevent this ensure that a thin and uniform layer is applied covered with a glass fiber filter and a moderate temperature selected to improve accurate and moisture content readings.
For test samples that are pasty or contain fat or substances that melt the use of a glass fiber filter is advantageous to increase the surface area of the sample. In addition, moisture analysis of substances which form crusts (e.g. glucose syrup) or pasty substances (e.g. butter) can be considerably improved by mixing with quartz sand. You can purchase a box of 200 filter pads or buy a case of 4000 filter pads to save even more money.
Many people call us looking for the absolute best value Precision Weighing Balances can offer in a moisture balance for simple moisture determination applications like sludge wastewater applications and the answer again and again is the A&D ML-50. When price is the #1 factor and you want a quality moisture determination instrument to 1% moisture content determination then you should review the ML50 moisture balance HERE.
Before you buy any moisture balance be sure to see the Sartorius MA35 moisture analyzer since we made a special purchase and selling them so low that the manufacturer won't let us advertise the price. Because our price on the Sartorius MA35 is lower than the manufacturer's "minimum advertised price," Sartorius does not allow us to show you our price until you take further action by placing the item in your shopping cart.
The Sartorius MA35 heating element is metal tubular and this provides more of an oven effect providing intense heat throughout the complete heating chamber thus allowing better drying to all sides of the sample (top, bottom and sides). Although the metal tubular design isn't the fastest design for drying to run the percent moisture test since metal tubular takes longer to heat up over a halogen bulb we feel it is the best method to determine moisture.

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 Ohaus 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 MB35 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 Ohaus MB35 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 DO NOT RECOMMEND THE MB-35 FOR PLASTIC APPLICATIONS OR FOR TESTING PLASTIC OR NYLON OR RESIN SAMPLES. THE ONLY MOISTURE ANALYZER WE RECOMMEND FOR THIS APPLICATION IS THE MA100C***
