Wastewater Moisture Analyzer - Percent Solids Tester

Not sure what Sartorius Moisture Balance is best for you?

The best way to approach this type of inquiry is as follows:

1. Sartorius has an on-line database of hundreds of samples that have been tested on Sartorius' Moisture Analyzers at www.sartorius.com. You can look up your sample online for the best model Sartorius Moisture Analyzer recommended for the application and the settings for the sample run. The database provides technical information including initial sample weight, temperature setting, average analysis time and percent moisture for the particular sample. A good example is coffee.

2. If you do not find your particular sample in the database, then you can receive a FREE Dry Run Test Kit. With the Dry Run Kit, you simply send a sample to the Sartorius Applications Lab. Call Sartorius directly at 631-254-4249 for your FREE Dry Run Test Kit and send it to Sartorius Corporation, 131 Heartland Boulevard, Edgewood, NY 11717. Sartorius' lab will test your sample on different Sartorius Moisture Analyzer models and with different parameters to find the best unit and settings for your sample. Sartorius has over 90% success with this technique!!! It takes all the guess work away.

When these value added services are considered buying a Sartorius moisture analyzer is simple and convenient.

If you're attempting to find the moisture content on small samples under 1 gram we found a detailed technical paper that thoroughly evaluated the Sartorius MA50C and MA50H online here.

For more than 25 years, Sartorius has been a leading supplier of equipment for rapid gravimetric moisture analysis. Throughout the world you'll find Sartorius Moisture Analyzers in Sewage Treatment Plants to determine percent solids for primary, secondary and tertiary processes, Food processing plants for determining moisture to yield the longest possible shelf life of your food product, cosmetic, pharmaceutical and hundreds of additional applications.

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 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.
