Our glass separating funnel is a precision laboratory instrument crafted from high-grade borosilicate glass, designed for safe and efficient liquid-liquid separation and extraction. Featuring a leakproof stopcock and clear graduated scale, it enables controlled release of immiscible liquids, with excellent chemical resistance to acids, alkalis and organic solvents. Suitable for academic research, pharmaceutical testing, food analysis and environmental monitoring, it ensures stable performance and accurate phase separation in routine and specialized lab operations.
This glass separating funnel is core for separating immiscible liquid phases, widely applied in sample pre-treatment of environmental, pharmaceutical and food tests to isolate target components precisely for subsequent analysis.
It extracts active pharmaceutical ingredients from herbal extracts and separates impurities from drug solutions, meeting lab-scale purification demands for pharmaceutical R&D and small-batch drug preparation.
Used in food testing labs, it separates fat, pesticide residues and pigments from food samples, providing qualified pre-treated samples for chromatographic analysis to ensure food safety compliance.
It extracts organic pollutants, oil and surfactants from wastewater and surface water, achieving efficient phase separation to support accurate detection of water contaminants and environmental assessment.
Ideal for separating essential oil layers from aqueous distillates, its non-adsorptive glass surface retains active ingredients, serving cosmetics, flavor and fragrance industries’ extract preparation.
With strong corrosion resistance to solvents and reagents, it separates reaction mixtures in fine chemical pilot production, ensuring the purity of intermediates in batch chemical synthesis processes.
As a standard lab teaching tool, it demonstrates liquid-liquid separation principles intuitively, helping students master basic extraction operations and understand core chemical separation technologies.
This glass separating funnel is essential for separating immiscible aqueous and organic layers, widely used in sample pretreatment for environmental, pharmaceutical, and food testing to ensure accurate component isolation before instrumental analysis.
It extracts active pharmaceutical ingredients from herbal extracts and separates impurities from drug solutions, supporting lab-scale R&D and small-batch preparation while complying with basic laboratory quality standards for pharmaceutical processing.
Applied in food laboratories, it isolates fat, pesticide residues, and pigments from edible oils, beverages, and meat samples, providing reliable pre-treated samples for chromatography to meet food safety detection requirements.
It efficiently extracts organic pollutants, oil, and surfactants from wastewater and surface water, enabling clear phase separation to support precise quantification of contaminants and accurate environmental quality assessment.
First, check the stopcock for leaks and close it tightly. Pour mixed liquids into the funnel, then let them stand until fully separated. Open the stopcock slowly to drain the lower layer, and close it once the interface reaches the stopcock. Finally, remove the upper layer separately for complete separation.
