Warning - Moisture balances should 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 MB25 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-25 FOR PLASTIC APPLICATIONS OR FOR TESTING PLASTIC OR NYLON OR RESIN SAMPLES.  THE ONLY MOISTURE ANALYZER WE RECOMMEND FOR THIS APPLICATION IS THE MA100C***

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.
