To properly prepare the IDF & SDF bags for Kjeldahl and Ashing procedures, refer to Section 17 of the TDF Operator’s Manual (Ash Determination) or view the following video: Kjeldahl & Ashing Bag Preparation .

Refer to the TDF Operator's Manual, sections "IDF/SDF Analysis" and "TDF Analysis."

In the past, we recommended customers to de-fat in XT4 bags. When the defatting process was completed, the XT4 bags were cut up and placed in the IDF bag. If the XT4 bag is cut into very small pieces, the sharp edges of the cut pieces can penetrate...

It is possible to follow an NDF run with an ADF run using the same sample and Filter Bag. However, samples that are high in pectin, tannins, glucans, and fructans can produce lower-than-expected ADF values when NDF was run first. This is because...

F57 The porosity of the ANKOM F57 Filter Bag is 25 microns. The design of the filter bag provides a three-dimensional filter matrix similar to the filtering effect of a glass crucible. The F57 Filter Bag provides equal filtration without the manual...

Possible Causes: (1) The dial on the heat sealer may not be turned up high enough. To seal the XT4 Bag, the dial must be set at approximately "6." (2) The heating element is broken. On the sides of the Teflon cover are two shiny metal strips that...

Refer to Service Procedure High Blank Bag Values (DES035).

The Blank Bag Correction allows for a weight adjustment based on actions that take place during solubilization. The resulting factor increases or decreases your sample bag weight. To determine the blank bag correction, include at least one empty...

Depending on what you are testing, refer to section ADF Analysis, NDF Analysis, or Crude Fiber Analysis in the DELTA, A200, or A2000 Fiber Analyzer Operator's Manual.

We have found that it is best to slowly ramp up the digestion temperatures so that foaming in the digestion tubes is minimized. As a result, we would suggest the following times and temperatures: 15 minutes at 150°C, followed by 15 minutes at 250°C...

Test the rinse water with litmus paper during the last minute of the fourth hot water rinse. If the test indicates the presence of acid, repeat with fresh, hot water until a neutral pH is achieved.

Possible Causes: (1) The dial on the heat sealer may not be turned up high enough. To seal the XT4 Bag, the dial must be set at approximately "6." (2) The heating element is broken. On the sides of the Teflon cover are two shiny metal strips that...

Refer to the Fat Extraction Process section of the ANKOM XT10 Extractor Operator's Manual. See subsection, Sample Preparation Procedure for Crude Fat.

The F57 and F58 Filter Bags are ash-free and therefore can be used for ash determination. Refer to the Ashing Procedure Service Procedure (AS034) linked below.

Refer to Service Procedure Insert Samples Into F58 Bags (AS032).

To minimize bag material abrasion, use the new bag suspender (as of March 2015 - Part #: F11 ). It has been redesigned to include rounded bottom points on each tray.

IDF filter bags have a shorter length of clear polypropylene material and a taller filter at the bottom of the bag. SDF filter bags have a longer length of clear polypropylene material and a shorter, wider filter at the bottom of the bag.

Bag breakage can occur when the heat sealer setting is not hot enough to ensure a good seal. Make sure each bag is sealed within 4mm of its open end. This section includes a narrow polypropylene strip that provides elasticity to the heat-sealed area...
