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 ...
PFA vials with threaded closures designed primarily for storage of samples. Available with flat, conical and rounded inner style configurations. Some vials are molded with solid outside bottoms for use on hot plates.
All vials also available in packs of 10 with tray. For vials with tray, add the letter "T" to the end of each catalog number for this configuration.
All Plain Closure (Non-Septum) PFA vials available with PTFE liner inside closure. Add the letter "L" to the end of each catalog number for this configuration.
For distillation of strong alkalis or acids and for aggressive solvents. Can also be used for the distillation of pure liquids which should not come into contact with glass. An important advantage of this apparatus is the transparent reaction vessel with a large opening and a very smooth interior surface. Reactions, such as vaporization, boiling or bubbling, as well as the filling height, are visible in this reaction vessel. This apparatus can be heated by a heated bath, by an electric heating jacket, or on a hotplate, but should not exceed a temperature of 200°C in the reaction vessel. Stirring with a PTFE-coated magnetic stirring bar is possible when the flat bottom of this transparent reaction vessel is heated on a hotplate. The ...
