The MEDILAB Buchner Funnel with Thin Stem is a precision-engineered porcelain filtration funnel designed for vacuum filtration of chemical, biological, and analytical samples. Featuring a fixed perforated plate and a refined thin stem outlet, it ensures smooth filtration flow and consistent separation. Its robust construction makes it essential for laboratories requiring reliable, contamination-free solid–liquid separation in routine and high-precision workflows.

Key Features

• Manufactured from premium, chemical-resistant porcelain
• Fixed perforated plate ensures stable support for filter papers
• Thin stem facilitates controlled liquid discharge and vacuum compatibility
• Glazed inside and outside (except rim) for easy cleaning and sample purity
• High mechanical strength and chip-resistant body
• Heat-resistant, chemically inert, and suitable for repetitive filtration cycles
• Smooth interior finish reduces sample adherence and enhances flow efficiency

 Material Specifications

• Material: Laboratory-grade porcelain
• Thermal Properties: Withstands moderate heating during filtration processes. Resistant to thermal shock when used properly
• Chemical Properties: High resistance to acids, alkalis, and most laboratory reagents. A glazed surface minimizes porosity and contamination
• Mechanical Properties: Strong ceramic body with reinforced walls and stable base
• Standards: Manufactured under ISO-aligned quality and dimensional control

Technical Specifications

• Available Sizes: Multiple diameters and capacities to fit standard filter papers
• Design: Fixed perforated plate, Thin stem outlet for improved vacuum performance
• Dimensions & Tolerances: Consistent shape and plate perforation pattern for uniform filtration
• Calibration: Not required
• Accessories: Compatible filter papers available separately

 Handling & Precautions

• Do not expose the funnel to sudden temperature changes
• Use with the appropriate filter paper size for best performance
• Clean with non-abrasive detergents; avoid metal scouring pads
• Do not exceed recommended heating limits; avoid open flame contact
• Ensure proper support when used with the vacuum apparatus
• Store securely to prevent chipping or breakage

 Applications

• Routine laboratory filtration in academic, industrial, and research labs
• Solid–liquid separation in chemical, pharmaceutical, and biotech processes
• Sample clarification, recrystallization, and precipitate collection
• Essential for QC/QA departments requiring consistent filtration results
• Ideal for microbiology, analytical chemistry, and general lab workflows
