300ml FEP gas wash bottle, wide mouth

Product Overview

The FEP Gas Washing Bottle is an essential component for high-purity gas purification, solvent stripping, and analytical gas scrubbing. Designed to replace fragile glass assemblies, these bottles allow gases to be bubbled through a liquid medium to remove impurities or to saturate the gas stream with a specific vapor. Because FEP is virtually chemically inert and features extremely low extractables, it ensures that neither the gas nor the scrubbing liquid is contaminated by the vessel itself. This makes it the gold standard for laboratories performing environmental air monitoring or semiconductor-grade gas analysis.

Bespoke Customization Services

We offer extensive design flexibility to meet your specific gas-handling requirements:

• Tailored Capacities: Available in standard volumes (e.g., 100ml, 250ml, 500ml, 1000ml) or custom-sized vessels for large-scale scrubbing.

• Internal Tube Configurations: The inlet tube length and diameter can be customized; we can also provide perforated PFA/PTFE spargers at the tip to create finer bubbles for increased gas-liquid contact area.

• Variable Connection Ports: Can be equipped with GL-threaded caps, PFA compression fittings, or tapered joints to ensure a leak-proof interface with your existing tubing.

• Dual-Bottle Manifolds: Custom-engineered series or parallel configurations for multi-stage gas purification.

Product Synergy & Workflow

• PFA Tubing & Fittings: Provides the primary gas intake and exhaust lines, maintaining a fully inert fluid path.

• PTFE Valves: Used to control gas flow rates or to isolate the washing bottle during system maintenance.

• FEP/PFA Bottles: Often used as secondary trap bottles or collection vessels for the scrubbed liquid.

• Inert Hot Plates: Can be used to warm the scrubbing liquid to increase the solubility of specific gas-phase impurities.

Application Fields & Industries

• Environmental Analysis: Scrubbing of ambient air samples to capture trace pollutants for ICP-MS or Ion Chromatography analysis.

• Semiconductor Industry: Purifying carrier gases or removing acidic/basic vapors from exhaust streams in wet-bench environments.

• Specialty Chemical Synthesis: Removing moisture or unwanted byproducts from gas streams during air-sensitive reactions.

• Isotope Analysis: High-purity gas handling where the isotopic integrity of the sample must be protected from vessel contamination.
