Description
This Filtering Flask with Integral Sidearm is made of durable, chemical-resistant borosilicate glass, engineered to withstand vacuum filtration pressure in laboratory environments. The integral sidearm offers a secure hose connection for vacuum lines, making it ideal for suction filtration procedures involving Büchner funnels and filter papers.
The flask features a thick-walled design that ensures both safety and strength during negative pressure operations. Graduated volume markings allow for accurate measurements during filtration, extraction, and distillation tasks. Commonly used in microbiology, analytical chemistry, and industrial quality control settings.
