Why are peristaltic pumps used in extraction experiments?

Extraction, just as its name implies is to withdraw the essence, in production practice and science research, extraction is generally divided into solid-liquid extraction and liquid-liquid extraction, solid-liquid extraction are common in our daily life, such as tea, tea with boiling water, the organic composition in tea into the water, this is a simple solid-liquid extraction process, and fluid extraction is a solute, From one shift to another kind of solvent in solvent process, still in tea, for example, through the organic composition in leaves dissolve into the water, at this point, the organic composition of water and the tea, we call it "extraction concentrate", but this time with no water-soluble solvent came in and had to stay in the water of the organic composition, found it is more in tune with the new solvent aura, Then the organic components come out of the water and go into the solvent, which is a simple extraction process.

Solid-phase microextraction technology 3354SPME is a new sample pretreatment technology, solid-phase extraction is one of the best sample pretreatment methods, has the advantages of simple, cost-saving, simple automation, SPME has been widely used in environmental and water treatment, clinical medicine, case handling, national defense and so on.

The needle of the SPME device is connected with melted quartz fiber, and the surface is coated with the chromatographic stationary phase. Generally, the fused quartz fiber is hidden in the needle, and the quartz fiber can be pulled out from the needle by pushing the sampler if necessary.

With the wide application of peristaltic pump, peristaltic pump plays a very important role in experimental extraction.

Peristaltic pump in experimental extraction advantages:

(1) The flow is accurate, and the micro drainage can be completed according to the actual demand.

(2) The sample liquid shall not contact other equipment except the pump pipe to prevent the sample from being contaminated

(3) Protect the safety of staff when collecting corrosive and hazardous samples.
