  • 24*(0.2-0.5ML) /24*2ML
developed specifically to meet the standard for chlorophyll a determination in water quality - "Spectrophotometric Method for Chlorophyll a Measurement in Water - HJ 897-2017" established by the Ministry of Ecology and Environment of China.
Application of Standard Method for Chlorophyll Extraction:
1. Filtration: add magnesium carbonate suspension before filtration to prevent pigment decomposition. The negative pressure should not exceed 50 kPa.
2. Chlorophyll extraction: place the filter membrane in a DHFSTPRP-Ch24 extractor, add 10 mL of 90% acetone solution, and grind at 1500-2000 rpm for 1 minute. The broken filter membrane floats the planktonic algae cells. After grinding, soak and extract at 4℃ in the dark for 15 minutes to 24 hours. Finally, centrifuge for clarification: centrifuge at 1000g for 20 minutes or filter, and transfer the supernatant to a stoppered glass vial.
3. Measurement method: spectrophotometry. Use the tricolor equation to determine the absorbance at 664 nm, 647 nm, 630 nm, and 750 nm to calculate the chlorophyll a, b, and c contents. Use the single-color equation to determine the content of demagnesiated chlorophyll a after calibration.
DHFSTPRP-Ch24 can simultaneously process 8×10mL centrifuge tubes, etc. for rapid cell disruption, cell lysis, and tissue homogenization.
Sample grinding includes plant roots, stems, leaves, flowers, fruits, seeds, and certain animal tissues; it is particularly suitable for the extraction of nucleic acids, proteins, and other components in plant tissues. In addition, it can also crush yeasts, cultured animal cells, bacterial cells, etc. to extract their components.
The three-dimensional integrated shaking mode makes the sample grinding more uniform and sufficient, with good repeatability of samples and no cross-contamination between samples. It is a true high-throughput grinding and oscillation system. Each sample can be completed in only 1-2 minutes.
The Eupervs accessory can be selected for low-temperature grinding and preservation of temperature-sensitive samples.


Applicable Samples and Applications:
1. Fast grinding preparation for PCR (polymerase chain reaction) of multiple samples.
2. Rapid tissue homogenization for nucleic acid extraction, RNA/DNA extraction, and protein extraction.
3. Lysis of yeast and bacterial cells.
4. Pesticide/Insecticide analysis (sample processing for residual pesticides or toxic substances in food using LC/MS/MS).
5. QuEChERS method (extraction of pesticides, antibiotics, and drugs).
6. Extraction of active pharmaceutical ingredients (APIs).
7. Food safety (contamination, adulteration, food traceability).
8. Grinding and homogenization of biomass for biofuels.
