Dynamic oscillating pressure extraction

The fundamental goal of extraction is to separate molecules from samples and ensure the integrity of the target compounds. Therefore, the extraction recovery rate is the core of the technology, and the design goal is to achieve the extraction effect with high recovery rate, which is safer and easier to operate and manage. Different from static pressure extraction, two-way reflux of extraction liquid is

realized in the pressure chamber, and dynamic pressure oscillation is generated by internal and external pressure difference. The effective pressure is high, and higher recovery rate is achieved.

Dynamic oscillating pressure extraction technology perfectly combines pressurized fluid extraction and solid-phase discrete extraction to improve compound precipitation efficiency.

The fully automatic process includes reagent addition, extraction, filtration, cooling and separation. Compared with static pressure extraction, the recovery rate is higher, the repeatability is better, the time is shorter, the sample volume is larger, and the solvent consumption is less. A single sample only needs 20ml of solvent, the extraction speed is 6 times higher than static pressure extraction, and the extraction is completed in 5 minutes, As a scientific research laboratory instrument, it is suitable for rapid extraction of pharmaceutical ingredients.

One click operation for 5 minutes to complete the automation of the whole process of extraction, filtration and separation

1) Automatic sample loading the automatic sampler loads the q-cup into the working chamber and automatically covers the pressurized seal.

2) Two way automatic solvent addition solvent is automatically added from the bottom and top to soak the sample.

3) Automatic heating and automatic heating of the two-way pressure extraction chamber increase

the extraction pressure of the working chamber, form a two way reagent cycle by dynamic

pressure oscillation, and force the solvent to disperse between the compounds, accelerate the extraction process and quickly complete the extraction conditions.

6-20 times of extraction speed, higher recovery.

4) Automatic extraction liquid collection and instant cooling once the extraction is completed, online automatic filtration and purification will be carried out. The extraction residue will be directly separated from the extraction liquid. The sample will be filtered out through the filter membrane. Under pressure, the reagent will pass through the super long cooling coil and be cooled instantly for 1 second to ensure that it is cooled to room temperature when entering the collection bottle.

5) Automatic cleaning function: the residue is directly separated from the extract. After automatic filtration and collection, the instrument will be cleaned automatically.
