Powder characteristics
White, yellowish-brown peel pieces.
1 The starch grains are mainly flat, round, elliptical, or triangular in shape, with a diameter of 30-40 μm. They are lenticular and conchoidal in lateral view, and are 11-19 μm wide. They are slightly pointed or obtuse at both ends, and the umbilical point is cracked. Less complex particles, composed of 2-4 or more particles.
2 transverse cells into a sheet, slender cylindrical, length 28-232μm, diameter 6-21μm, wall rosary thickening.
3 Pericarp Epidermal cells are oblong or long polygonal, with a length of 64-220 μm, a diameter of 16-42 μm, and thickening of wall beaded.
4 The middle layers of the skin are elongated or irregular, with thickened rosary.
5 Non-glandular single cells, 40-950 μm in length, 10-30 μm in diameter, and 5-10 μm in wall thickness.
Automatic Nucleic Acid Extractor
Nucleic acid extraction instrument is an instrument that automatically completes the nucleic acid extraction of samples by applying the supporting nucleic acid extraction reagents. Widely used in disease control centers, clinical disease diagnosis, blood transfusion safety, forensic identification, environmental microbial testing, food safety testing, animal husbandry and molecular biology research and other fields.
Using magnetic beads as the carrier, using the principle that magnetic beads adsorb nucleic acid under high salt and low pH value, and separate from nucleic acid under low salt and high pH value, and then move the magnetic beads or transfer the liquid to realize the entire extraction and purification process of nucleic acid. Due to the uniqueness of its principle, it can be designed into a variety of throughputs, which can be extracted from a single tube or 8-96 samples, and its operation is simple and fast. It only takes 30-45 minutes to extract 96 samples, which greatly improves the The experimental efficiency is low and the cost is low, so it can be used in different laboratories, and it is the mainstream instrument on the market.
