Pyrex hopper for the Harrells Precision Powder Measures
The Harrells Hoppers come in the standard size which holds approx 1 pound of most powders.
This is a direct replacement for the plastic bottle. It will screw right in and give you a much wider mouth to pour in powder.
They come with an improved custom cap that has an O-ring to seal the hopper and help keep moisture out. They also come with a custom baffle to insure consistent powder drops.
