Summary A simple, relatively inexpensive refractometer has been developed for use in testing flaxseed and soybeans for oil iodine number. The refractometer reads directly in iodine‐number units and the temperature correction thermometer is likewise calibrated to read directly in iodine‐number units. With this refractometer and a simple, hand‐operated laboratory hydraulic press, an operator with little technical training can test flaxseed or soybean samples for oil iodine numbers at the rate of about one test every five minutes. It is anticipated that this instrument will prove to be very useful in the routine testing of flaxseed, soybeans, and possibly certain other oil‐bearing seeds.
