For Gentle, Efficient Boiling; Prevent Superheating

Ultra-pure, virgin PTFE chips promote gentle, efficient boiling and help to prevent superheating, even of highly volatile liquids. Ideal for continuous extraction methods, such as EPA SW846 and EPA Method 1664 for oil and grease. Stones minimize "bumping" during reflux and distillation.

Not affected by boiling acids, hydrocarbons, ketones, esters, alcohols or alkalies. Easily cleaned and non-contaminating. Show no trace of face acidity or alkalinity. Will not scratch or abrade glassware and leave no powdery residue. Usable up to 550°F (288°C).

Large-size stones are used in environmental labs with "slow dry" concentration tubes. A stone is placed in the uninsulated region to promote a more normal boiling rate without sacrificing the "slow dry" advantages of the insulated tip.
