Glass Filtration Assembly

HPLC Solvent Clean-Up All-Glass Filtration Assembly

  • Durable all-glass filtration system—ideal for HPLC solvent clean-up applications

Designed for solvent purification and particulate removal prior to HPLC analysis, this all-glass filtration assembly ensures that liquids contact only high-quality borosilicate glass, maintaining chemical purity and minimizing the risk of contamination.

The integrated base design features an integral vacuum connection positioned above the filtrate drip point—effectively preventing contamination of the vacuum line with solvent droplets or aerosols.

Each assembly includes a glass funnel, a coarse porosity fritted glass filter support base with integrated vacuum port, and a collection flask with an inner joint connection. An aluminum clamp securely fastens the funnel and support base using standard 40/35 joints for stability and easy disassembly.

All components are fully compatible with Millipore and Kontes all-glass filter systems, allowing interchangeability with existing laboratory setups for solvent preparation and filtration.

Frequently Asked Questions

What is the benefit of using an all-glass filtration assembly for HPLC solvent clean-up?

All-glass construction prevents solvent contamination from plastics or metals, ensuring ultra-clean HPLC solvents and minimizing baseline noise in chromatograms.

Is the assembly compatible with existing Millipore or Kontes systems?

Yes. The filtration assembly’s 40/35 joints and component dimensions are fully compatible with Millipore and Kontes all-glass filtration apparatus.

What materials come into contact with the solvent during filtration?

Only borosilicate glass contacts the liquid, ensuring chemical resistance, low extractables, and compatibility with a wide range of HPLC solvents.
