Product Description

Straight Gas Washing Bottles are commonly used apparatus for gas washing, drying, and absorption in laboratories, precision‑manufactured from borosilicate glass 3.3. Featuring a straight inlet tube that delivers gas directly into the washing liquid, they offer simple structure, easy operation, and low gas resistance. Widely used in gas analysis, chemical synthesis, and environmental monitoring.

Key Features

Borosilicate glass 3.3: ISO 3585 compliant, thermal shock resistant to 280°C, excellent chemical resistance
Straight tube design: Simple structure with low gas resistance — ideal for applications requiring higher gas flow rates
High clarity: Pure, transparent glass allows easy observation of bubble condition and washing liquid status
Standard ground joints: Facilitates easy connection to gas tubing
Chemical resistant: Excellent resistance to most acids, alkalis, and organic solvents

Quality Assurance

Every unit undergoes rigorous dimensional inspection, leak testing, and visual examination to meet the high standards required in professional laboratories.

Note: Straight Gas Washing Bottles are designed for gas washing, drying, and absorption operations. Ensure the bottle is clean and dry before use. Maintain proper liquid level to ensure the straight tube outlet is submerged. Clean promptly after use to prevent residue buildup.

Applications

Typical Uses

Gas analysis

Washing, drying, and pretreatment of gas samples

Chemical synthesis

Purification and drying of reaction gases

Environmental monitoring

Gas absorption and enrichment in air sampling

Laboratory gas purification

Washing and drying of various laboratory gases

Teaching experiments

Gas washing and drying operations in gas property experiments

Compatibility Recommendations

Bottle + Washing Liquid

Select appropriate washing liquid based on gas properties (water, acid, alkali, organic solvent, etc.)

Bottle + Desiccant

Can be loaded with desiccant for gas drying operations

Bottle + Tubing Connection

Connect gas tubing via ground joints

Bottle + Porous Gas Washing Bottle

Can be used in series for multi‑stage washing and drying

Tip: Straight and Porous Gas Washing Bottles can be used together — straight type offers low resistance and simple structure, while porous type provides superior gas dispersion. Choose based on your gas treatment needs.
