Porvair Filtration Group’s PTFE membrane filters are designed to resist repeated steam cycles at high temperatures. The Fluorofil Plus filter cartridges have been tested to withstand 250 steam sterilisation cycles for 1 hour at temperatures of 142°C. The cartridges can also withstand steaming in the reverse flow direction at 142°C.Fermentation processes require a high degree of security and productivity – and Porvair believes that the ability to withstand steam sterilisation for longer periods and at higher temperatures results in better process security and a decrease in unnecessary and costly downtime.The company claims that its Fluorofil Plus filters also offer a number of advantages over standard filters. Benefits are said to include a lower pressure drop and more robust performance in fermentation processes, while the filters can also be steam sterilised, tested, and used multiple times. Furthermore, Porvair believes that repeated testing has shown that its Fluorofil filters can handle more steam sterilisation cycles than other models.The company says that its Fluorofil range of filters has a proven track record of success throughout the process industries, and applications include: cell culture, compressed air, fine chemicals and solvents, pure water supply systems (WFI), and powder handling and tableting.
