Jensen Inert Products Jensen Inert PTFE Boiling Stones, 1lb
Resistant to almost all chemicals Minimize superheating Ideal for boiling organic liquids Won't scratch glassware These ultra pure TFE stones promote gentle, efficient boiling, even of highly volatile liquids, and minimize bumping during reflex and distillation. They are ideal for continuous extraction methods (i.e., EPA SW846). They are not affected by boiling acids, hydrocarbons, ketones, esters, alcohols or alkalies. Easily cleaned and non contaminating, Jensen Inert TFE boiling stones show no trace of acidity or alkalinity and leave no powdery residue. Jensen inert boiling stones have the complete chemical inertness of TFE. They effectively promote gentle efficient boiling by having many projections on which small bubbles can form. Thus, small amounts of vapor are released at many places on the bottom of the flask or test tube, preventing superheating, with its erratic and undesirable bumping vaporization.
