Why choose this product

Premium Quality from USA

Whatman filter papers are manufactured in the USA, ensuring high standards for purity and consistency. Their pore size of 20-25 microns is ideal for sensitive lab applications, outperforming local alternatives that often lack uniformity. Imported directly, they arrive quickly in India, supporting precise research and testing needs.

Ideal for Indian Labs & Water Testing

Designed for liquid clarification, these papers suit Indian water analysis, environmental testing, and analytical labs. They are packaged 100 per box, offering cost efficiency and reliable results. Skip if your application requires sterile or air filters; these are for liquid and water analysis only.

How to use

  • Prepare the filter setup — Place the filter paper in the funnel, pour the liquid sample, and collect the filtrate for analysis, replacing paper after each test.
  • Ensure proper sealing — Secure the funnel to prevent leaks, and avoid overloading to maintain filtration efficiency.
  • Replace after use — Use a new filter paper for each sample to prevent cross-contamination and ensure consistent results.
