PTFE/Quartz Fiber Thimbles

Advantec PTFE Thimble Filters are seamless and high purity.  PTFE media is inherrently hydrophobic and contributes little or no trace metal contamination to the sample.   

Durable Fibrotic PTFE (Grade No.89) and PTFE/Silica Fiber (Grade No.89S) Thimble Filters are recommended for use at elevated temperatures or for sampling in areas where it is critical that the filter media be non-adsorptive with respect to acid gases.
