Ideal for continuous extraction methods. Stones minimize "bumping" during reflux and distillation. The boiling stones are not affected by acids, hydrocarbons, ketones, esters, alcohols or alkalis. They are easily cleaned and non-contaminating. Shows no trace of face acidity or alkalinity. They will not scratch or abrade glassware and leave no residue. Usable up to 288 °C. - Chemical resistant - Ideal for boiling organic liquids - Minimizes superheating 2 Saint Gobain Weight PK Cat. No. g 450 1 9.012 310 2 Balls, PTFE PTFE balls minimize "bumping" during boiling. They are inert and can be used up to 288 °C. 100 balls per package. - For column packing and mixing beds - Resistant to most chemicals - Non-contaminating 3 Saint Gobain Diam. PK Cat.

They are made of nickel-plated stainless steel and fluoropolymer coating. The coating eliminates surface buildup or loss of valuable sample due to sticking. Will not scratch or damage delicate surfaces. - Extra heavy-duty PTFE coatings - Resistant to low and high temperatures - Use for handling chemically active materials 4 Saint Gobain Description Length Figure PK Cat.

Chisel tip on one end and diagonal cut on other end permits applications in confined vessels. Chemically inert PTFE offers resistance to adhesion of any material. Unbreakable and heat resistant to 288 °C, they will not crack or break under severe conditions, such as thermal and mechanical shock, and will not scratch glassware. - Highly inert PTFE coating - Non-stick, easy to clean - Low and high temperature resistant 5 Saint Gobain Length PK Cat.
