Ohaus MB45 moisture analyzer has a weighing capacity of 45 grams, with a readability of 0.001g and repeatability to 0.015% when using a sample greater than 10 grams. An integrated database stores up to 50 drying procedures for maximizing productivity, simply recall the test from memory and begin. Use the statistical function for simple tracking and recording of standard deviation over time, the MB45 does all the calculations and provides the end result.
Additional features the Ohaus MB45 moisture balances offers includes:
Ohaus MB45 utilizes a dot matrix graphic display for quick setup and use, displays % moisture, % solids, % regain, time, temp, weight, test ID, drying curve & statistics
Halogen heating lamp for even heating with and four enhanced heating options and an operating temperature range from 50° to 200°C in 1° increments
Four selectable automatic drying programs allow for easy one step drying, simply set the temperature and time, and begin
The Ohaus MB45 is a full featured, compact moisture analyzer for every budget! Perfect for environmental, quality control, food and beverage, chemical, pharmaceutical industries, and more, this fast, rugged analyzer gives you the flexibility you need and the accuracy you require for moisture determinations. Ohaus MB45 combines state-of-the-art heating with highly accurate weighing technology to deliver a faster, more precise method of moisture analysis.

If you already own the Ohaus MB45 moisture analyzer and you are looking for the consumable moisture pans you can purchase a box of 500 aluminum moisture pans for an extremely low cost compared to what Ohaus charges for these moisture pans if you bought them from Ohaus direct. We also sell moisture balance filter pads used to distribute the heat better, prevents skinning over (this is when bubbles form). 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.
If you have any questions about your moisture application give us a call M-F 9-5 EST at 978-521-7095 and one of our experts can assist you in resolving your moisture determination application.
We made a special purchase on the Sartorius MA35 that the price is so low that manufacturer won't let us post the selling price until you "add to cart". Be sure to review the MA35 moisture analyzer since you'll probably be amazed how low the selling price is.

offers a great example of items the MB45 can determine the percent moisture
along with anticipated results, dry temperature and estimated measurement
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 MB45 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-45 FOR PLASTIC APPLICATIONS OR FOR TESTING PLASTIC OR NYLON OR RESIN SAMPLES. THE ONLY MOISTURE ANALYZER WE RECOMMEND FOR THIS APPLICATION IS THE MA100C***
Select from 4 Ohaus Moisture Analyzers to meet your weighing needs
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.
