The PFA Gas Washing Bottle is the ultimate solution for high-cleanliness gas scrubbing, purification, and solvent stripping. Designed for environments where even the slightest contamination is unacceptable, these bottles replace traditional glass when higher thermal stability and chemical purity are required. The non-porous, "low-memory" surface of PFA prevents the absorption of gases or impurities, ensuring that the vessel can be decontaminated easily for repeated, high-precision use in trace metal laboratories.
We offer a high degree of design freedom to match your specific gas-handling manifold:
Custom Internal Spargers: Available with straight tubes or porous PTFE/PFA frit tips to create micro-bubbles, maximizing the gas-liquid contact area for better scrubbing efficiency.
Modular Port Design: The cap can be precision-machined with multiple inlet/outlet ports, supporting standard PFA compression fittings or specialized flare connections.
Tailored Column Heights: Bottle height and internal dip-tube lengths can be adjusted to fit specific fume hood dimensions or to optimize gas residence time.
PFA Tubing & Fittings: Create a completely metal-free and leak-proof gas line from the source to the analyzer.
PTFE Needle Valves: Allow for the ultra-fine adjustment of gas flow rates into the washing bottle.
PFA Collection Vials: Ideal for receiving and storing the liquid fractions after the gas scrubbing process for immediate ICP-MS testing.
Secondary Trap Bottles: Can be configured in series to ensure 100% removal of volatile contaminants in complex gas streams.
Semiconductor Industry: Purifying specialty process gases and scrubbing acidic vapors from cleanroom exhaust.
Environmental Monitoring: Capturing trace-level atmospheric pollutants and heavy metals in high-purity absorption solutions.
Geochemistry & Isotope Analysis: Precise gas handling where the chemical and isotopic integrity of the sample must be strictly preserved.
Specialty Chemical R&D: Removing moisture or unwanted byproducts from reactive gas streams in organic synthesis.
