Powder Addition Funnel

These funnels facilitate the delivery of free-flowing, granular solids into reactions. The pressure equalizing arm is equipped with a vented stopper for air-free operations and it also permits access into the delivery stem for easy clean-out. A one piece, easily removed grooved PTFE auger delivers powders at a uniform rate. The 250 and 500mL capacities have the larger, deep cut auger (Size B) for use with coarse material. The funnel has a lower inner joint and top outer, both of the size listed. Replacement Augers are available by special order.

The 10 mL size with 14/20 joints (CG-1723-01) has an overall height of ~7-7/8"(200 mm) overall width of ~4" (102 mm), and knob diameter of 1.26" (32 mm).
