Product Description
Knowing your homogenate volume without a separate measuring step saves time, and this Potter-Elvehjem grinder has graduations fused right into the glass tube. Radial serrations on the PTFE pestle push the homogenate into the cylindrical section of the tube for efficient, even grinding.
