Single Glass Filter Holder SGFH
Vacuum filter aqueous, organic or corrosive liquids for particulate contamination analysis. Also recommended for HPLC solvent filtration. Contact membranes for filtering organic solvents and the suitable diaphragm vacuum pumps.
Specification :
Borosilicate glass parts in contact with liquid, with ground glass sealing surfaces. Vacuum connection to integral base and flask cap is above filtrate exit level, avoiding drawing filtrate into vacuum tubing.
Precision Filtration with the Single Glass Filter Holder SGFH
Achieve clean, contamination-free sample preparation with the Single Glass Filter Holder SGFH—a high-quality, borosilicate glass filtration unit designed for laboratory use under vacuum or gravity flow. Ideal for microbiological testing, environmental analysis, HPLC sample prep, and sterile filtration, the SGFH offers chemical inertness, optical clarity, and seamless compatibility with standard membrane filters.
Engineered for Purity and Simplicity
The SGFH Single Glass Filter Holder is crafted from borosilicate glass 3.3, providing excellent resistance to thermal shock and a wide range of aqueous and mild organic solutions. Its simple, single-sample design ensures minimal dead volume and easy visual monitoring during filtration. The holder accommodates standard membrane diameters (typically 25 mm or 47 mm) and features ground-glass joints or threaded ports for secure, leak-free assembly with funnels, flasks, or vacuum manifolds.
- Borosilicate Glass 3.3 Construction – Chemically inert, non-leaching, and resistant to most acids, bases, and solvents (excluding HF and strong alkalis).
- Compatible with 25 mm / 47 mm Membranes – Works with cellulose, nylon, PES, MCE, and other common filter types.
- Transparent Design – Allows real-time observation of filtration progress and filter condition.
- Autoclavable at 121°C – Suitable for sterile and aseptic workflows in microbiology and pharmaceutical labs.
- Low Extractables & Low Binding – Preserves sample integrity for sensitive analytical applications.
- Easy to Clean & Reusable – Smooth internal surfaces prevent residue buildup; ideal for repeated use.
Trusted in Analytical and Regulated Labs
The SGFH is a staple in water quality testing (e.g., total suspended solids, microbial enumeration), clinical diagnostics, and research labs where sample purity and visual control are essential. Unlike plastic holders, it won’t absorb organics or swell in solvents—ensuring accurate, reproducible results.
Whether you’re filtering culture media, clarifying environmental samples, or preparing standards for chromatography, the Single Glass Filter Holder SGFH delivers reliability, clarity, and lab-grade performance in a simple, elegant design.
Filtration you can see—and trust.
