PM-21 ABSORPTION TUBES, U – FORM

The U-Form Absorption Tube is an essential piece of laboratory glassware precision-engineered for gas absorption, moisture drying, desiccation, and chemical synthesis experiments. Crafted from high-transparency, heavy-wall borosilicate glass, this apparatus features a perfectly molded U-shape configuration with two open parallel vertical limbs. Designed to be filled with granular chemical absorbents—such as calcium chloride, soda lime, or silica gel—the PM-21 allows gases to pass smoothly through the tube layout, ensuring optimal chemical contact for efficient drying, purification, or extraction processes.
