Automated External Filtration System for Carbon Black and Other Additives of Small Particle Size in Polyolefins.

May 29 2017

Polymer Char’s External Filtration System, EFS is a breakthrough in external filtration, currently being the only automated system in the market capable of completely eliminating carbon black from samples in an effective and safe process. This automated apparatus also eliminates rests of catalysts and other additives of small-particle size that may be present in polyolefin samples.

The process is fast, easy and safe for the user since there is no solvent handling and no manual transfer of vials involved. It takes about 2 minutes for the sample to be clean and ready to be injected into the GPC instrument. After each filtration process, another one can be started right away, minimising the user’s dedication to the filtration tasks, which usually are tedious and consume significant amounts of time within the daily laboratory operations.

Thanks to its smart design, the solution travels through disposable cartridges only, so no-cross contamination may occur and no vapors are released to the ambient since the solvent circulates through a closed-circuit only; unlike the manual and traditional method that uses glass-fiber filters, or the available semi-automated equipment from other providers.
