Research and development plays an important role in the teaching of high school biology experiments, but most of the reagents used in the experiments are toxic or volatile. Experiments in middle school will cause certain damage to teachers and students. Continued use of traditional grinding equipment will no longer meet current teaching facts. Chuan Bran Biological combined with the characteristics and needs of high school biology experiment teaching, independently developed a grinding device-grinding filter that is more suitable for high school biology experiment teaching, and applied for a patent.
The grinding filter is a new type of experimental tool that combines grinding and filtering into two operating units. Particularly suitable for the extraction of soluble components of biological materials. Its fast and environmentally friendly features have greatly solved the problem of nervousness in high school biology experiment teaching. This instrument can be used in a wide range of applications, such as extraction and separation of chloroplast pigments, crude extraction and identification of DNA, comparison of Vc content in different fruits and vegetables, identification of reducing sugars and proteins, extraction of urease in soybeans, and nitrite content in kimchi. Determination and other experiments.
Conventional grinding device
1. The loss of reagent volatiles is large 1. The amount of volatiles is less than 2%
2. The grinding takes about 30 minutes. 2. The grinding takes 10 minutes.
