Abstract
A hydraulic press fitted with an adjustable torque wrench, together with a stand made of iron bars will form an auto-stop hydraulic press for making KBr disc in IR studies. Total material cost is about $100. All parts are readily available from the local hardware stores. The modified torque wrench is also useful to replace the lever in the standard laboratory press.
