Overview
CXC-06 crude fiber tester is a QIWEI brand product. According to the acid-base digestion method, the sample is digested and weighted to obtain the crude fiber content of the sample. It is suitable for the determination of crude fiber content in various feeds, grains, grains, foods, etc.
Features
1. Sample Handling by acid-base digestion method; 2. 6 samples can be measured each time; 3. Low repeatability error, absolute value error of crude fiber content below 10% ≤ 0.4%, absolute value error above 10% ≤ 4%; 4. Measurement time about 100 minutes, including picking, alkali washing, preheating, suctionfiltration and washing steps; 5. Power 2.5KW, power supply AC220V/50HZ; 6. Instrument size 680 × 280 × 650mm, gross weight about 32kg.
Principle
This instrument uses a fixed amount of acid and alkali, cooks the sample under specific conditions, and then removes the soluble substances with ether and acetone. After burning at high temperature, the amount of mineral substances is deducted, and the Balance is called crude fiber. Crude fiber is not an exact chemical entity, but a rough composition measured under generally accepted mandatory conditions, mainly including cellulose, a small amount of hemicellulose and lignin.
Applications
Feed, grains, cereals, foodstuffs, Miscellaneous agricultural and sideline products requiring determination of crude fiber content
Steps
1. Sample digestion treatment; 2. Use acid and alkali for picking and alkali washing; 3. Remove soluble substances with ether and acetone; 4. Burn the sample at high temperature; 5. Calculate the crude fiber content by weight measurement.
Notice
• Ensure that the power supply is AC220V/50HZ; • Pay attention to the safety of acid and alkali use during operation; • The measurement time is about 100 minutes, which needs to be planned reasonably; • The repeatability error needs to be within the standard range; • The instrument size and weight are large, and pay attention to safety when handling.
