High-purity cellulose thimbles hold solid and semisolid samples in the extraction system, prevent plugging, and provide reliable and reproducible results. Made from alpha cellulose, these thimbles have excellent mechanical strength. The thimbles dimensions accurately match Dionex ASE 350/150 System Extraction Cells to ensure an optimum fit during accelerated solvent extraction. Simplifies cell cleaning when extracting sticky samples or samples that melt at high temperatures. Enables direct weighing of samples and avoids sample loss during transfer. Prevents fine particulate samples from clogging the cell.
