Glass Vacuum Filter – Laboratory Vacuum Suction Filtration Device

The Glass Vacuum Filter is a laboratory‑grade vacuum suction filtration unit engineered for efficient liquid‑solid separation and ambient‑temperature stirring reactions. Built on a reinforced stainless steel frame with GG17 high borosilicate glass, this filtration system combines excellent chemical resistance, reliable vacuum performance, and easy operation. It is widely used for sample filtration, solvent purification, precipitate separation, and small‑scale reaction processing in chemistry, pharmaceuticals, cosmetics, materials science, and environmental labs.

Under vacuum pressure up to 0.098 MPa, liquid materials are drawn through a filter medium, separating solid particles from the liquid phase. The integrated stirring system ensures uniform mixing before filtration. After processing, filtered materials can be easily discharged through the bottom PTFE‑glass discharge valve. The fully transparent glass body allows real‑time observation of the entire filtration and reaction process.

• Leak‑proof PTFE sealing structure ensures stable vacuum and zero leakage
• High‑quality GG17 high borosilicate glass provides excellent corrosion resistance
• Convenient bottom discharge valve for fast and clean material collection
• Multiple capacities available: 10L, 20L, 30L, 50L to meet various lab demands
• Flexible selection for funnel and flask materials based on application
• Stable stainless steel support frame for safe and durable operation
• Customizable configurations for volume, materials, motors, and controllers
