Operating Instructions
Sample Drying
Follow the sample drying protocol in each specific procedure. Blotting reduces drying time for
hydrolysis samples. After completion of hydrolysis, the filter bags are blotted on paper towels. Place
the wet samples on four sheets of paper towel. Place two sheets on top of the bags. Uniform pressure
(ANKOM Blotter or similar) is used on top of the paper towels to gently press the water out of the
bags. ANKOM Blotter (part #H35) is foam cushioned and weighs ~10 lbs. After one minute repeat
the blotting process for two minutes prior to placing them into the ANKOM
RD Dryer.
1. Remove the filter by lifting up both filter latches and set the filter to the side.
2. Place processed or blotted filter bags into the bag holder. Hydrolyzed samples may use the HCl bag
holder in the ANKOM
RD
Dryer.
3. Place the bag holder into the ANKOM
RD
Dryer and attach the filter.
4. Turn on the ANKOM RD Dryer. The fans, then the heater, will automatically turn on.
5. Press <set> on the temperature controller and use the Up and DOWN arrows to set the drying
temperature. Push <set> to enter the temperature. Use the temperature listed in the assay method.
(usually 110
o
C)
6. Dry the samples for the required time and turn the instrument off.
7. Remove the filter. Remove the samples and immediately place into a desiccant pouch. Cool to room
temperature and weigh.
