Thermo Scientific GCF400 Flask 4L with Foam Ring for Savant SpeedVac

Thermo Scientific GCF400 4-Liter Glass Condensation Flask with Insulating Foam Ring for Savant SpeedVac Systems. A heavy-walled glass vapor trap reservoir designed to capture and condense evaporated solvents, protecting vacuum pumps and maintaining optimal vacuum levels during centrifugal vacuum concentration.

Condition: (1) Flask - new; (2) foam ring - excellent used condition.

• MPN / Catalog Model: GCF400
• Manufacturer & Line: Thermo Scientific (Savant) / SpeedVac Concentrator Accessories & Vapor Traps
• Volumetric Capacity: 4.0-Liter (4 L) collection capacity, supporting extended evaporation runs and high-volume sample drying without frequent emptying
• Material Construction: Heavy-walled, thermal-shock-resistant borosilicate glass engineered to withstand deep vacuum pressures and extreme cryogenic temperature differentials
• Included Insulating Ring: Comes complete with a fitted high-density closed-cell foam insulating ring that seats the flask securely within the refrigerated vapor trap chamber while minimizing ambient thermal transfer
• Solvent Vapor Retention: Acts as the primary cold trap condensation vessel, freezing out and accumulating aggressive organic solvents, aqueous vapors, and volatile acids before they can migrate to the vacuum pump
• System Compatibility: Direct replacement condensation flask engineered for Thermo Scientific Savant refrigerated vapor traps, including the RVT400, RVT4104, RVT5105, and integrated SpeedVac vacuum concentrator workstations
• Operating Function: Preserves high vacuum pump oil integrity, prevents internal mechanical corrosion, and reduces hazardous atmospheric solvent exhaust
• Primary Application: Centrifugal vacuum concentration, DNA/RNA oligonucleotide drying, proteomics sample preparation, drug discovery compound evaporation, and lyophilization/freeze-drying pre-trapping
