The Latest In Lightweight And Less Expensive Poly Mixers

Mixing tanks are used in several different types of manufacturing and business. The tanks are used to blend various components together. Mixing tanks come in all types of materials including plastic, glass, hard rubber and steel. Stainless steel was once widely used because it was easy to clean. However, the biotech and biopharm industries are using more PTFE and plastics for mixing tanks.

The use of mixing tanks in manufacturing is common. Large containers of raw materials are placed into large tanks to make a variety of substances. For instance, in a bakery, a mixing tank may contain flour, yeast and water. The ingredients are smoothly blended together for baking. Many mixing tanks have paddles or agitators to mix ingredients together. PTFE and other plastics are leach-resistant, making the materials a better choice over materials like stainless steel. Stainless steel is still the industry standard for tanks that use agitators. However, more users prefer plastics such as polyethylene and polypropylene for tank and mixer impeller assembly because deliveries are faster and it’s more cost effective. Benefits include:

  • plastics are non-metallic
  • lighter weights
  • portability
  • simpler and lower cost maintenance

Further, many of the plastic tanks meet USP Class VI standards and can be steam-cleaned at high pressure. Using plastics also means faster production. To learn more, visit These lighter systems can be built in less than six months, and they still meet all sanitary requirements. Solid poly mixers are made in kynar, polypropylene and polyethylene and may be supplied with USP VI and FDA grades of plastics.

The biotechnology and biopharmaceutical industries have safer, more efficient mixing equipment. They are used for buffer prep, solution hold and multiple use blend tanks. People who need ultra-pure storage should investigate the new Teflon PTFE barrier. This technique offers an inert surface with no extractables and no ionic contamination. In addition, the Teflon PTFE vessels cost far less than traditional fluoroplastic tanks. The new technology is very useful for environments that need to be sanitary. Additional uses include cell culture mixing and blending, biotech buffer prep, hospital storage tanks and lab mixing and blending.
