Sartorius MA35 is extremely popular with wastewater treatment facilities. WWTP utilize electronic digital moisture balances like the Sartorius MA35 to free wastewater operators from performing gravimetric drying method using a standard oven and balance. Automated moisture determination instruments like the MA35 from Sartorius enable operates to make their rounds. Additional applications could be in paper mill industry for black liquor applications. If you are transporting sludge you want to know your percent solids so you are not paying sludge haulers to transport too much water verses solids.
People call us constantly asking us what is the best moisture balance for their applications with so many models on the market - "I don't know what to choose, please HELP". These same people also find most companies selling moisture balances whether a catalog company, industrial supply firm, or "supposed online scale company" know nothing about the moisture analyzers. We really feel this is an injustice since if a company doesn't know what they are selling then they shouldn't be selling the product to begin with, but this is something we can't control. Moisture balance manufacturers all want their product advertised online and now moisture balances are becoming a commodity sold on price when in reality they are specialized piece of equipment.
Precision Weighing Balances our only business is balances and we like to promote and tout the best product. In our opinion, if the product works for your moisture determination application and is priced right we'll get return business and customer referrals.
For most applications the Sartorius MA35 moisture balance is the best moisture analyzer when considering all the factors. The only exception that comes to mind would be for plastic applications or other substances where the moisture content readability of less than 0.01% is required. For moisture content test requiring readability to 0.001% we would recommend the MS70. PET plastic pellet measurement typically have very low percent moisture less than 0.300% moisture and needing readability to 0.001% and the MA35 moisture balance displays moisture content to only 0.01%.
Determining moisture in: powders used in some manufacturing process; the food industry for ingredients like flour, powdered milk, corn meal; ingredients for ice cream; the wastewater industry for percent solids in primary and secondary sludge then the MA35 moisture balance is a great choice.
Sartorius is a global leader in weighing instrumentation and has been building balances since 1871. You name the brand whether it is A&D Weighing, Ohaus, Mettler-Toledo and the numerous other smaller companies and none compare to the expertise in building balances over a longer period of time. You may pay a little more for Sartorius but you are paying for their expertise and a product that works! Over the last few years we have seen many no name brands enter the moisture balance market and most are built with cheap strain gauge loadcells that are total JUNK.
The MA35 is Sartorius' replacement to the ever popular MA30. We don't have the numbers but probably the MA30 is the most commonly used moisture balance in the world for units sold. Sartorius discontinued the MA30 in 2003.
The MA35 heating element metal tubular design isn't the fastest for drying the percent moisture test since metal tubular takes longer to heat up over halogen but we feel it is the best method to determine moisture correctly. Many people call and ask "how fast can I determine the moisture" when really they should be asking "how consistent and accurate are the results with this moisture analyzer over the competitor's moisture analyzer and our answer is always buy the Sartorius MA35 moisture balance.
Halogen is the cheapest heating element to manufacturer and the halogen bulbs burn out. On many models you have to send the moisture balance to the manufacturer for a costly replacement. The metal tubular rarely burns out or at least we have never had a customer call saying they needed to replace the Sartorius MA35 heating element. Since halogen cost less these moisture analyzers are typically less than the Sartorius, but in the long run for downtime and repair cost to replace the heating element the Sartorius will cost you less to operate.
Also halogen consistently overshoots the temperature. If you set the temperature to 110°C the heat on the sample might spike to 120°C or 130°C and then then temperature fluctuates 107°C > 113°C > 108°C > 112°C but the temperature never stabilizes to the actual setting of 110°C. These over shots and excessive temperature on your sample may result in burning of organics and incorrect moisture results.
The metal tubular might take 120 seconds to heat to 110°C but it really is 110°C ± 1°C. So sure halogen might go to 110°C in 30 seconds but what good is it if your sample is degraded in the process.
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
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 MA35 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 MA35 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.
MA35M-1US Moisture Analyzer
Sartorius has relaunched the MA35 as of August 2016 after it was discontinued and replaced with the Sartorius MA37. The original model was MA35M-000115V1 and the relaunched model is MA35M-1US. The relaunched model has all the same features and specifications as the original model. The MA35 is Sartorius' entry level moisture analyzer for simple moisture determinations of sludges and foods products. Sartorius MA35M-1US offers tactile keypads and LCD and a great low price while the Sartorius MA-37 features a more expensive touchscreen display.

MA35 Moisture Analyzer sets a new benchmark in compact moisture
analysis at a budget price. Designed as an entry level
unit for customers demanding a robust unit at a low price.
Sartorius MA35 moisture balance offers a maximum weighing
capacity of 35g with 1mg or 0.01% resolution. Ideal
for quality control applications, the MA35 moisture analyzer
produces GLP compliant printouts and can easily be connected
to a PC for data collection.
The compact, space saving design is complemented by an easy to read backlit
display and a manual flip up cover which opens wide for easy
access to the chamber. Performance functions and operating
concept are geared toward a daily routine process such as
repetitive QC monitoring of samples, as performed during in-process
control and incoming goods inspection.
Made even more user-friendly by removing seldom used programming
options without compromising flexibility or measurement accuracy.
Sartorius MA35 conforms to FDA requirements when optional
metal panels are in place of glass window panels (See the FDA version HERE that has metal panels installed). If
you're working in the food processing industry the FDA/ HACCP
regulations do not want instrumentation with glass in the
production area for food, since if glass breaks it would create
a hazard and could fall into the food.
Typical applications for this moisture analyzer include regular
random sampling and incoming inspection in the food and beverage,
chemical, pharmaceutical, and building materials industries
as well as in environmental monitoring. You name
it, the MA35 will analyze it - wherever you need to obtain
fast and reliable moisture analysis results.
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 MA35 Moisture
Determination 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.
