Product Description
Speed up routine gravity filtration and pouring with a funnel angle designed around filter paper. Because folded paper forms a 60 degree cone, a 58 degree funnel holds it by the top edge and leaves most of the cone free to filter instead of just the tip, saving time on every sample.
This listing is for Kimble catalog number 28950-75: KIMAX Short Stem Funnel, 90 mL, Case of 48. Short stem funnels are made from low extractable 33 expansion borosilicate glass designed from ASTM E1095, Type I, Class A. They resist chemical attack and mechanical and thermal shock. Eight sizes are offered, from 3 mL to 225 mL capacity, with stem lengths from about 40 to 97 mm for use in a wide range of flasks and bottles. LIGHT LABS ships genuine DWK Life Sciences products with knowledgeable support from our Englewood, Colorado team.
