Rice Test Filter Flask

Heavy-Duty Borosilicate Laboratory Filter Flask for Vacuum Filtration and Rice Testing

The CANTROL Filter Flask (also known as a Büchner flask) is an essential component for laboratory vacuum filtration and asphalt Rice testing procedures. Designed with thick, high-quality borosilicate glass, this flask is engineered to withstand the intense pressure differentials required for efficient liquid-solid separation and air evacuation.

This Filter Flask features a heavy-duty side arm (tubulature) for secure connection to vacuum hoses and pumps. Its conical shape and stable base make it ideal for supporting heavy filtration assemblies, such as Büchner funnels. Whether used in chemical analysis, soil testing, or asphalt binder extraction, this unit provides the durability and chemical resistance necessary for rigorous laboratory environments.

Key Technical Advantages:

• Pressure Resistance: Reinforced glass walls designed specifically for vacuum applications to ensure safety and performance.

• Side-Arm Design: Integrated glass tubulature for quick and airtight connection to standard laboratory vacuum tubing.

• Versatile Use: A critical tool for the Rice Test (Theoretical Maximum Specific Gravity) and other asphalt laboratory procedures.

• Chemical Durability: Fabricated from premium borosilicate glass to resist thermal shock and a wide range of corrosive chemicals.

• Standard Fit: Designed to be compatible with various rubber stoppers and filtration funnels for seamless lab integration.
