LAWSON (Luo Shang China) company has developed a new tissue grinder in accordance with the Ministry of Environmental Protection, the standard for chlorophyll a "Determination of Chlorophyll a in Water Quality Spectrophotometry" HJ 897-2017.

Application of DHFSTPRP-Chlorophyll24 standard method for extracting chlorophyll:

1. Filtration: Before suction filtration, add magnesium carbonate suspension to prevent pigment decomposition. The negative pressure cannot exceed 50kPa.
2. Chlorophyll extraction: place the filter membrane in the DHFSTPRP-Ch24 extractor, add 10ml of 90% acetone solution, grind at 1500-2000rpm for 1min . Disrupt phytoplankton algal cells on the filter membrane. After grinding, soak in the dark at 4°C for extraction, and the soaking time is 15min to 24h. Final centrifugation for clarification: centrifuge at 1000 g for 20 min or filter and transfer the supernatant to a stopper glass vial.
3. Determination method: Spectrophotometry, three-color equation to measure the absorbance at 664nm, 647nm, 630nm, 750nm to calculate the chlorophyll a, b, c chlorophyll content. Determination of pheophytin a corrected content by monochromatic equation

DHFSTPRP-Ch24 Rapid cell disruption, cell lysis, and tissue homogenization can simultaneously process 8×15 mL centrifuge tubes, etc.

Grinding samples include plant roots, stems, leaves, flowers, fruits, seeds and certain animal tissues; it is especially suitable for the extraction of nucleic acids, proteins and other components in plant tissues. In addition, it can also crush yeast, cultured animal cells, bacterial cells, etc., so as to extract the components therein.

The three-dimensional integrated oscillation mode makes the sample grinding more uniform and sufficient, with good sample repeatability and no cross-contamination between samples. It is a real high-throughput grinding and oscillation system. Each sample only takes 1-2 minutes to complete.

For temperature-sensitive samples, Ningbo Luoshan accessories can be selected for cryogenic grinding and preservation.

DHFSTPRP-Ch24 Applicable samples and applications:

1. PCR (polymerization) Enzyme chain reaction) rapid multi-sample grinding preparation 2. Rapid lysis of tissue homogenate for nucleic acid extraction, RNA/DNA extraction, protein extraction 3. Lysis of yeast and bacterial cells 4. Pesticide/Insecticide Analysis (Testing of food residue pesticides or toxic substances in LC/MS/MS sample processing
5. QuEChERS method (Pesticide, antibiotic, drug extraction)
6. Pharmaceutical active ingredient APIs extraction
7. Food safety (contamination, adulteration, food traceability)
8. Biofuel sample processing
