High Performance Cellulose Extraction Thimbles Cellulose extraction thimbles are produced from high-quality alpha cellulose cotton linter and have excellent mechanical strength and retention. Standard single thickness thimbles have a wall thickness of approximately 1mm (10.0µm nominal particle retention). Double thickness thimbles have a wall thickness of approximately 2mm (6.0µm nominal particle retention) for applications where higher retention and increased wet or dry strength, or rigidity are required. The high purity of the materials ensures reliable and reproducible analytical results. [B]Available in packs of 25.[B]*Double wall thickness - 2mm**Fits Soxtec Extractor
