Accurately and safely observe your reactions! Inert borosilicate glass construction with PVC coating for safety Millimeter reference scale to mark changes in your sample volume Aero-Tech's pressure reaction vessels allow for full observation of chemical reactions in a safe vessel. These vessels are made from heavy wall, inert borosilicate glass with a PVC safety coating. Each vessel is graduated with a millimeter reference scale. These pressure reaction vessels are sometimes referred to as “Fisher and Porter Bottles”. They are ideal for viewing reactions of mixed compounds and viewing temperature and pressure changes to liquids or gasses. Typical applications include hydrolysis, hydrogenation, polymerization, catalysis and isomerization. Other uses include corrosion studies, solubility studies and spray and pressure characteristics of compounds. All reaction vessels are pressure tested to 2x their pressure rating. Specifications Capacity 9 oz Internal liquid volume 250 mL Max operating pressure 100 psi
