Barnant Co., of Barrington, Ill., introduces a dual-headed version of its popular Easy-Load pumphead. A simple lever release allows users to change two tubing lines without disassembling the pumphead in less than 30 seconds. Each pumphead accepts two tubing lines of 13, 14, 16 or 25 sizes, for dispensing precise doses from 0.06 to 1.7 ml per revolution. With the standard 600 rpm motor drive, this arrangement allows up to 1,000 ml/min flow rate per channel, or 2,000 ml/min total.
