ST-04BS Kjeldahl nitrogen analyzer(4 holes)
ST-04BS=ST-04B nitrogen still+ST-04C digital digestion furnace
ST-04BS nitrogen analyzer (also known as protein analyzer) is a
series of products designed by our company based on the principle
of Kjeldahl nitrogen determination. It is mainly used to detect the
content of ammonia nitrogen, protein nitrogen, and other substances
in grains, food, dairy products, beverages, feed, soil, water,
drugs, sediments, and chemicals. The test results meet the
indicators specified in GB/T6432-2018.
Technical parameters:
It takes about 40 minutes for the electric heating furnace to
digest a batch of samples. The harmful gas such as sulfur dioxide
escaped from the digests is discharged into the sewage from the
water through the drainage pipe on the furnace through the gas
extraction tee.
