A gas washing bottle treats a gas by bubbling it through a liquid. Gas enters through a tube that reaches near the bottom of the bottle, rises through the liquid as bubbles and leaves through an outlet at the top. Along the way the liquid can scrub out impurities, dry or humidify the gas, or absorb a component for analysis.
A sintered glass disc on the inlet breaks the gas into much finer bubbles for better gas-liquid contact. The classic design is the Drechsel bottle.
Gas washing bottles are used to scrub and wash gases, dry gas streams over sulfuric acid or other drying liquids, humidify gases, trap components for analysis and treat reaction off-gases before venting. They appear in synthesis and research labs, in analytical sampling trains and in environmental gas analysis. Empty bottles also serve as safety traps between a reaction and a bubbler to stop suck-back.
The bottle is borosilicate 3.3 glass with a ground-glass head carrying two tubes: an inlet that runs down to near the base and a short outlet at the top. The inlet ends in an open tip or a fused sintered disc for fine bubbles. Head and bottle are matched through the ground joint, and amber glass is available for light-sensitive absorbing solutions.
Fill with the washing or absorbing liquid to well below the outlet, connect the inlet to the gas source and the outlet onward, and check the flow direction; reversing the connections can push liquid back up the line. Watch for suck-back if the gas supply stops. Choose a fritted inlet only where fine bubbles are needed, because it raises back-pressure. Keep each head with its own bottle.
We form the bottle and head from borosilicate 3.3, set the tubes, grind the joint to match the bottle and anneal the assembly. Where specified, sintered discs are fused into the inlet in the porosity you need. Joint fit, tube placement and frit porosity are checked in production. Options include hose barbs or ground joints on the tubes, screw-cap GL heads and amber glass. Send us your capacity and inlet type for a quote.
Customization
We specify the container, closure, decoration and transit packing as one package, so every part fits and arrives ready for your filling line.
Choose from standard sizes or request a custom capacity. We supply drawings with tolerances, label panel dimensions and nominal and brimful capacity.
We match caps, liners, pumps, droppers and stoppers to the neck finish and check the seal against your contents and filling process.
Flint, amber and colored glass, with frosting, spray coating, screen printing, hot stamping or labels. Material documentation is available on request.
Partitioned cartons, layer pads or bulk pallets, with shipping marks and pallet patterns planned for your route and warehouse.
Applications
Typical markets and uses. Tell us your contents, filling process and storage conditions and we will recommend the right model and components.
We confirm availability of the standard model, and review any changes to size, color, decoration or tooling for feasibility and lead time.
We send samples and specification sheets so you can check dimensions, component fit and finish before you place the order.
Your quotation covers packing design, shipping route, Incoterms and export documents, so landed cost is clear from the start.
