The VACUU-VIEW Extended model monitors pressure conditions from atmospheric pressure down to 10-3 mbar/Torr, making it suitable for freeze dryers, Schlenk lines, molecular distillation and other "fine" vacuum processes.
According to the characteristics of components and the purpose of distillation, atmospheric pressure, vacuum, steam, and molecular distillation can be applied flexibly to the separation.
The molecular distillation technology was also called short films.
Flexitech does not involve any form of high-temperature treatment such as molecular distillation; and it does not involve the use of other solvents besides ethanol and water.
Kirkland Signature Natural Fish Oil, new from Issaquah, Wash.-based Costco Wholesale Corp., is said to be sourced from deep-ocean fish and obtained through state-of-the-art molecular distillation, used to help remove polychlorinated biphenyls and dioxins.
Omega-3 EEs are then separated from other EEs by molecular distillation. This process enables selective concentration of eicosapentaenoic acid and docosahexaenoic acid, in excess of levels in natural fish oil.
Single or multiple stage systems in various configurations are optimized for molecular distillation, evaporation, concentration, plus hybrid column fractionation.
Mustela's Sunflower Oil Distillate is obtained using an exclusive two-step, extraction and molecular distillation process to yield an ingredient that is concentrated in tocopherols, phytosterols and essential fatty acids while being free of proteins, making it extremely well-tolerated and safe for those with nut allergies.
Cod liver oil is similar to fish oil, but most products also contain high levels of vitamins A and D (molecular distillation removes these vitamins).
Illinois-based InCon uses molecular distillation technology to concentrate a range of compound products such as Omega-3 fish oil.
The traditional method that is used to create concentrated oil is called molecular distillation. In this process, the oil is subjected to repeated rounds of elevated temperature in the presence of a vacuum to help concentrate and purify it.
The pumps find applications in vacuum coating, molecular distillation, vacuum metallurgy, freeze drying, vacuum impregnation, air conditioning and refrigeration, vacuum lifting devices and packaging machines.
