Instruction
Parallel evaporator is an instrument used for isolation and purification of multiple samples simultaneous. The principle of parallel evaporation is to remove solution continuously and effectively by reducing pressure, which reduces boiling point (bp) of solution, increasing surface area, and optimizing temperature control depending on distilled solvent and analyte(s). Additionally, it comes with a vortex technology that reduces the possibility of solvent bumping. Besides, it is recommended to use with a cold trap, such as circulating or refrigerant condenser, to minimize the risk of solvent emission.
The staple distilled solution of parallel evaporator is solvent and chemical solution, hence a chemical resistant vacuum pump made of polytetrafluoroethylene (PTFE) should be best choice. There are rules for pump selection, for example, the flow rate of pump is directly proportional to total volume of evaporation tubes and containers. Moreover, vacuum requirement varies depending on boiling point (bp) of distilled solution. Therefore, vacuum controller is a recommended accessory for accurate vacuum controlling to prevent solvent bumping and significantly shorten evaporation process.
Applications
- Food safety testing, such as pesticide and antibiotic analysis
- Pharmaceutical industry, such as components extraction
- Clinical labs, such as drugs and metabolite testing in blood, urine, etc.
