Crude fiber tester

The principle of the crude fiber tester is to use acid and alkali of accurate concentration, digest the sample under specific conditions, and then use ethanol to remove the soluble matter. After high temperature burning, the amount of minerals is deducted, and the content is called crude fiber. (According to the principle of acid-base washing method, it integrates acid and alkali treatment and washing. The method of fully enclosed electric heating, liquid addition, digestion, filtration, and washing is used to determine the crude fiber content. The sample does not need to be transferred during operation. It can decompose the crude fiber in the substance, and at the same time, it can be adjusted arbitrarily one by one according to the required temperature, so as to achieve the purpose of accuracy and speed.)

 

 

 

Product Range:

 

The crude fiber tester is used to detect the content of crude fiber in various grains, feeds, grains, foods and other agricultural and sideline products.

 

Main features:

 

1. The digestion device of the crude fiber tester adopts high-quality ceramic heating materials, which has good thermal efficiency and can fully obtain the digestion effect.

 

2. All extraction processes can be operated by automatically placing valves, and each sample can be operated independently for the entire set of tests.

 

3. Built-in imported peristaltic pump, corrosion-resistant, vacuum filtering and adjustable vacuum degree, gas can be blown back to accelerate the washing effect.

 

4. The crude fiber tester can be equipped with a circulating constant temperature water bath for high-precision temperature control.

 

5. The height of the sample can be upgraded and adjusted to facilitate sampling and discharging.

 

6. The experiment process of the whole set of crude fiber tester is completed automatically, without manual operation.
