Cellulose extraction thimbles 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.
