Product Description
Weigh and transfer in one step with a funnel that sits flat on the balance pan and threads onto the receiving vessel. Weighing directly in the funnel eliminates a transfer from a weigh boat, improving accuracy when working with small quantities of solid or liquid.
This listing is for Kimble catalog number 747585-0013: KONTES Transfer/Weighing Funnels, 20-400, 45 mm Wide. These funnels are designed for use with micro volumetric flasks as accessories for MICROFLEX threaded kits. Two versions fit 13-425 and 20-400 threads, about 45 mm and 50 mm wide. They are made from 33 expansion, low extractable borosilicate glass meeting USP Type I and ASTM E438, Type I, Class A. Add it to your LIGHT LABS order alongside the rest of your glassware and closures.
