Product Description
Pouring solvent onto a packed chromatography column can disturb the bed and ruin a separation. These solvent addition funnels let eluent run gently down the column wall instead, protecting the top layer of silica gel and keeping bands sharp during loading.
This listing is for Kimble catalog number 629050-0000: KONTES Polypropylene Solvent Addition Funnel. Each funnel has a closed-end design and a perforated stem that directs solvent outward against the column wall. The set includes five polypropylene funnels: 60 mL, 120 mL, 240 mL, and two 960 mL versions with 50 mm and 70 mm stem lengths, covering a range of column diameters. Add it to your LIGHT LABS order alongside the rest of your glassware and closures.
Key Features
- Gentle solvent delivery – Perforated stem sends solvent down the column wall.
- Closed-end design – Prevents a direct stream from hitting the silica bed.
- Set of five – Sizes from 60 mL to 960 mL for different columns.
- Polypropylene construction – Lightweight and resistant to common eluents.
