Review: Cela fait plusieurs fois que je fais confiance à cette marque et dans différents "grades" de filtration. Rien à dire. Le produit est fiable, robuste (pour créer des zones de filtrations dans des environnements de cultures mycologiques) et d'un bon rapport qualité prix. Review: Exactly what I needed for my Krups since it was discontinued. Found some on ebay without box for much more. These are fairly priced and work perfect. ## Features - GRADE 2 : 9cm - Equivalent to Whatman qualitative grade 2 standard lab filter paper (90mm) - AGRICULTURE - Soil pre-filtration fertilizer analysis nutrient absorption in seed tests - BREWING TESTS - Beer and malt analysis removal of turbidity in wort and yeast filtration - AIR / GAS FILTRATION - Pollution monitoring of specific atmospheric contaminants smoke - HIGH RETENTION / SLOW FLOW - Retains fine crystalline particles (5~10 micron) ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07MHNF5H4 | | ASIN | B07MHNF5H4 | | Batteries Included? | No | | Batteries Required? | No | | Customer Reviews | 4.6 4.6 out of 5 stars (38) | | Customer reviews | 4.6 4.6 out of 5 stars (38) | | Date First Available | 10 July 2019 | | Date First Available | 10 July 2019 | | Item Weight | 60 g | | Item model number | ST002-90 | | Item model number | ST002-90 | | Manufacturer | Fluted Filter | | Manufacturer | Fluted Filter | | Part number | ST002-90 | | Product Dimensions | 9.3 x 9.3 x 2 cm; 60 g | | Product Dimensions | 9.3 x 9.3 x 2 cm; 60 g | ## Images ![9 cm Lab Filter Paper, Standard Qualitative Grade 2 - Slow Flow 90 mm (100 Discs) - Image 1](https://m.media-amazon.com/images/I/71H8Y4ymNIL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by B***N on 4 June 2025* Cela fait plusieurs fois que je fais confiance à cette marque et dans différents "grades" de filtration.
