Sartopore~R 2 XLM: A Next-Generation 0.1-mu m Filter for Media

摘要

Filters rated at 0.1 mu m have been increasingly used for cell culture media filtration due to concerns about mycoplasma contamination of cell cultures. Sartorius Stedim Biotech has recently launched a new 0.1 -mu m, mycoplasma-retentive, sterilizinggrade filter: Sartopore~R 2 XLM. It is a heterogeneous, double-layer PES membrane filter with a highly asymmetric 0.2-mu m prefilter layer in-built with the same 0.1 mu m mycoplasma-retentive final membrane as its predecessor Sartopore~R 2 0.2/0.1. Sartopore~R 2 0.1-mu m. 10" cartridges have been validated as mycoplasma-retentive by testing at a third-party laboratory using a modified ASTM F838-05 method to show removal of Acholeplasma laidlawii at LRV = 7/cm~2.
