Product Description
Recover small quantities of solid with minimal loss using a compact fritted Hirsch funnel. It is ideal for microscale work where every milligram counts, and a choice of porosities lets you match the frit to the particle size of your product.
This listing is for Kimble catalog number 955250-7526: KONTES Fritted Hirsch Funnel, 4-5.5 µm, 75 mm. Made from low extractable 3.3 borosilicate glass meeting USP Type I and ASTM E438, these funnels are offered in fine (4-5.5 micron), medium (10-15 micron) and coarse (40-60 micron) porosities. Choose from several sizes to match your sample volume and filter flask. LIGHT LABS ships genuine DWK Life Sciences products with knowledgeable support from our Englewood, Colorado team.
Key Features
- Three porosities – Fine, medium and coarse frits available.
- No filter paper – Fritted disc collects solids directly.
- Microscale friendly – Compact design minimizes sample loss.
- Low extractable glass – Meets USP Type I and ASTM E438.
