PM-25 ABSORPTION TUBES, NESBIT

The PM-25 Gas Washing Bottle is an advanced, highly efficient piece of laboratory glassware designed for gas purification, scrubbing, drying, and precise vapor treatment. Crafted from premium borosilicate glass, this apparatus stands out with an innovative structural design: an external delivery tube channels incoming gas down to the bottom of the cylinder, freeing up internal chamber volume and ensuring optimal gas-liquid contact as bubbles rise through the solution. The top neck features a precision ground-in key stopper that manages both fluid lines simultaneously. A simple rotation of the stopper instantly opens or blocks both the inlet and outlet tubes, providing immediate fluid containment without the need for external clamp valves.

Key Features

• Simultaneous 2-Way Rotary Key Stopper: The precision-ground glass stopper acts as an elegant, dual-line control valve. Rotating the top key opens or completely blocks both the inlet and
outlet paths at the same time, simplifying system isolation during multi-stage experiments.

• Space-Saving External Delivery Tube: Designed with a specialized external bypass arm that safely delivers incoming gas directly to the bottom reservoir, maximizing bubble path travel
while keeping the central basin unobstructed.

• Premium Borosilicate Glass Construction: Manufactured with uniform, heavy walls from inert borosilicate glass 3.3 to provide exceptional thermal shock resistance and complete immunity to
aggressive scrubbing reagents or concentrated acids.

• Stable Cylindrical Base: Features a flat-bottomed, compact cylindrical profile that fits securely into standard laboratory clamps, multi-tube manifolds, and crowded workstation benches.

• Fire-Polished Hose Side ports: Both horizontal connection tubes at the top are meticulously fire-polished to ensure airtight, tear-free fitting of flexible rubber, PVC, or silicone
laboratory hoses.
