The MEDILAB Funnel Filtering is a precision-crafted laboratory funnel made from premium Borosilicate Glass 3.3 for efficient and reliable filtration processes. Designed with a 60° bowl angle and a smooth, narrow stem, it ensures optimal flow control and compatibility with standard filter papers. This funnel is essential for accurate sample transfer, clarification, and separation in research, industrial, and analytical environments.

 Key Features

  • Made from Borosilicate Glass 3.3: Exceptional resistance to chemicals, thermal shock, and mechanical stress.
  • 60° Bowl Angle: Ensures efficient filtration and correct seating of filter papers.
  • Smooth Surface Finish: Allows uniform flow without sample retention.
  • High Transparency: Easy visual monitoring of fluid levels and filtration progress.
  • Compliance with DIN ISO 4798 & USP Standards: Guarantees international dimensional and quality consistency.
  • Uniform Wall Thickness: Ensures durability and reduces breakage risk.
  • Straight, Long-Stem Design: Improves flow control and minimises splashing.
  • Autoclavable & Reusable: Suitable for repeated sterilisation and long-term lab use.
