Ultra-pure, virgin PTFE chips promote gentle, efficient boiling and help prevent superheating, even of highly volatile liquids. Ideal for continuous extraction methods, such as EPA SW846. These chips are not affected by boiling acids, hydrocarbons, ketones, esters, alcohols or alkalies. They are easily cleaned and non-contaminating. They will not scratch or abrade glassware and leave no powdery residue.
