The new Sartorius MA37 is Easy - Easy to clean, Easy to operate, Easy to handle.
The MA37 replaces the prior Sartorius models MA35 and MA30. There is also a new Sartorius MA160 (replaces MA45, MA150) that offers additional features to the MA37.
This new moisture analyzer supports the operator – not the other way around. The MA37 has a new powerful 480W heating element over its predecessor MA35 which was only 360 Watts. Most competitor brands on the market are only 360 watts. More watts means faster heating up = faster analysis time.
The MA37 could be used for moisture analysis to determine moisture in: powders used in some manufacturing process; the food industry for ingredients like flour, powdered milk, corn meal; ingredients for ice cream; pet foods then the MA37 moisture balance is a great choice.
If you are performing moisture analysis on lots of different samples the MA160 is recommended over the MA37 for the additional features "Method development - in 3 easy steps" and "File Management", but if you're testing the same sample over and over again like sludges for waste water treatment plants or black liquor in the paper industry the MA37 is the economical choice. The Sartorius ReproEasy Performance Test Pad and Sample tong are optional accessories with the MA37, but standard equipment with the MA160.
The MA37 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 MA37 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 MA37 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.
Watch this video below to learn how the MA37 can be configured, see the display and how to access the parameter configuration. You'll see all the steps to run a moisture test. This video is a must see.
USB Port - The back of the Sartorius MA37 has a Mini USB port, Fastening point for an optional Kensington
key lock and AC power socket. You can transfer weighing results to Microsoft Windows programs without additional software.
New Powerful Heating Elements
Sartorius MA37 metal heating elements delivers up to 480W. The prior model was the Sartorius MA35 and it had a maximum output of 260 watts.
If you want even greater power be sure to see the Sartorius MA160 with its AURI heating elements outputting 600W.
Status light / Acoustic Signal
status light indicates the process status
light ON = running / START
light flashes = process finished / STOP
light OFF = analyzer OFF
light flashes = error
The Status light with acoustic signal allows the operator of the moisture analyzer to perform other task while easily following of the process steps and time for a distance of up to 33 feet away.
The process status light located on the top of the heating module indicates the progress of an analysis run so you can conveniently check the remaining time, even from a distance of 33 feet. During the measurement, the process status light on the analyzer flashes, if the light has not been switched off in the menu. When the moisture analysis is finished running the test the process status light on the analyzer flashes three times and then goes out. The status light allows you to perform other tasks in the lab while the moisture analyzer is determining the moisture analysis without you standing next to the unit to figure out when the test has been completed.
BetterClean Design is an exclusive from Sartorius
The innovated BetterClean Design is an exclusive from Sartorius. End user feedback was they wanted a moisture balance that was easy to clean and they did not want a heating source that would be damaged from cleaning. The new MA37 & MA160 allows the sample chamber plate, hood and included grid to be removed and placed in a dishwasher for easy cleaning. The heat tubular heating element can be cleaned unlike those other moisture analyzers that use a halogen bulb and if one touches the halogen bulb causes premature failure. Oils in your skin can cause hot spots on the glass envelope that will result in considerably shortening its life, and may even cause the bulb to burst. Salts in your sweat can also cause problems. All those issues are eliminated with the Sartorius moisture analyzer heating element. The Adam PMB53, all the AND Weighing moisture analyzers like the MX50 and the Ohaus MB25, MB35 and MB45 all use a halogen bulb
The touchscreen features
An intuitive user interface with a easy to use menu and structured user navigation makes the MA37 one of the easiest to use moisture analyzers on the market today. Sartorius designed the MA37/MA160 with a "capacitive touchscreen" similar to your smartphone. Beware there is a huge difference in "capacitive touchscreen" verses "resistive touchscreen" used by other moisture analyzer manufactures and if you want to see the difference check out this youtube video. Resistive touchscreen displays are not responsive to the slightest touch, require more pressure or a stylus, and the pixel resolution is typically less, out of focus, blurry, not crisp enough and dull. Want to see more watch our video on the Sartorius Secura (MA37 use the same display) verses the Ohaus Explorer Pro.
The display offers a visual weighing capacity aid
Display of the moisture drying curve
Sartorius designed the MA37 moisture analyzer with a great display that is intuitive and simple to use.
Analysis in Minutes Not Hours.
MA37 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 MA37 moisture balance offers a maximum weighing capacity of 70g with 1mg or 0.01% resolution. Ideal for quality control applications, the MA37 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 touch screen with Sartorius graphical user interface 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.
Sartorius MA37 conforms to FDA requirements. 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 MA37 will analyze it - wherever you need to obtain fast and reliable moisture analysis results.
Watch this video above as we highlight in this video the differences between the MA37 and MA160 since briefly looking at the units they seem the same but there are major differences.
So both the MA37 and MA160 deliver readability to 1 milligram. The average repeatability is ± 0.2% when you are using an initial sample weighing from 1-5 grams and when using a initial sample greater than 5 grams the repeatability is 0.05%. We always recommend a sample at least 5 grams since anything smaller is typically difficult to attain a good representative sample. Neither unit is recommended for plastic resin applications.
So what are the differences??
Although the infrared heating element looks similar the MA37 maximum output is 480W while the MA160 is 600W. More watts shortens time to attain temperature setting. The heating elements differ from a different alloy mix for the metal tubular heating element and Sartorius calls the MA160 element AURI.
MA37 has only the ability to save one (1) method while the MA160 can save up to 100 methods.
MA160 comes with "Sample Tongs" while it is an accessory for the MA37.
MA160 includes 3 ReproEasy Pads while no pads are included with the MA37. The ReproEasy Pads are used to verify the moisture analyzer is functioning within manufacturer specifications. The pad is a onetime use consumable item and additional pads are sold in packages of 10 pads. We recommend you download the user manual and reference the section "MA Performance Test" to learn more about this test feature available on both the MA37 and MA160. This is a great alternative to testing your moisture analyzer against sodium tartrate dihyrate. Using sodium tartrate dihyrate requires you to operate at 160C to release the chemically bonded two water molecules from Sodium Tartrate. The ReproEasy Pad you can run a performance test at 70C, 100C or 130C whichever temperature is closer to your actual sample you test normally.
The MA160 has a SD memory card slot verses the MA37 just has a dummy slot. You can import/export methods to the SD card. This is a nice feature for companies that implement "build alike" or create SOP implemented globally throughout their plants. One plant can develop the method for each different sample, download those methods to the SD card and the e-mail the file to other plants where they can copy the file to the SD card and then import them into the MA160 located in other locations.
In the "Calibration Report" menu you can access the most recent calibration reports for the MA Performance Tests and external calibration adjustments up to 99 reports are saved per day. Calibration reports older than 30 days are automatically deleted. Again this information can be downloaded to the SD Card and the file e-mailed to the quality control or regulatory officer to meet compliance reporting requirements.
Another benefit purchasing the MA160 because it has the SD card is the "Results" menu. The analysis results can be viewed, exported or deleted. If you export the data to the SD card it is saved as an XML file and can be viewed with a web browser like Internet Explorer or Firefox. This is a great feature especially for paperless operations or if you need to print results and don't have a Sartorius YDP30 or YDP40 printer. All you need to do is save results to the SD card, open the file on your PC within a web browser and use the printer connected to your computer.
I would say the greatest feature the MA160 has that isn't available on the MA37 is "Method Assistant". Method Assistant helps you develop and refine methods in 3 easy steps. Its quick and ensures that all relevant parameters have been included for your moisture determination test. The Assistant prompts you to configure all relevant parameters, provides a practical range and prevents you entering implausible data. If you are running lots of different samples and not sure on the optimum temperature, whether you should use filter pad(s) The intuitive wizard asks you whether your sample consistency is a solid, fluid or paste. Method Assistant even asks if the sample is organic, inorganic or unknown.
Finally there is a 'Protective Mode" menu that is only available on the MA160. This allows you to password protect the MA160 moisture analyzer to ensure only authorized persons can make changes to the system settings. This video is a must see.
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 MA37 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 MA37 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 MA37 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.
