Product Description
Side-Arm Filtering Flasks are specialized containers for vacuum filtration in laboratories, precision‑manufactured from borosilicate glass 3.3. Featuring a side tube at the upper body for connection to a vacuum pump, they create a negative‑pressure environment inside the flask for efficient solid‑liquid separation and sterile filtration when used with filter assemblies such as Büchner funnels, sintered glass funnels, or membrane filter holders. Widely used for HPLC mobile phase filtration, buffer sterilization, particulate removal, and sample preparation, they are essential tools in pharmaceutical, chemical, biological, and food testing laboratories.
Key Features
- Borosilicate glass 3.3: ISO 3585 compliant, thermal shock resistant to 280°C, excellent chemical resistance
- Side tube design: Upper‑body side tube allows easy connection to a vacuum pump for negative‑pressure filtration
- High clarity: Clear glass body enables easy monitoring of filtration progress and filtrate collection
- Uniform wall thickness: Maintains structural integrity under vacuum conditions
- Multiple capacities: Available in 125mL, 250mL, 500mL, 1000mL, 2500mL, 5000mL, 10000mL, 15000mL, and 20000mL
Quality Assurance
Every unit undergoes rigorous dimensional inspection, wall thickness testing, and visual examination to ensure safety and reliability during vacuum filtration operations.
Note: Side-Arm Filtering Flasks are designed for vacuum filtration operations. We recommend operating at a vacuum pressure not exceeding 0.08MPa. Inspect the flask for cracks or defects before use to prevent breakage under negative pressure.
