The funnel for collecting the oil and water portion tapers from 8 inches to 5/8 inches with a 3-inch length. The oil and water are collected in a 30 ml. at 20EC. pharmaceutical graduate manufactured according to the National Bureau of Standards Specifications.) The drained weight is the weight of the sardines remaining on the screen after a 3 minute draining period.
