Deluxe Boyle's Law Apparatus, 1 Each

The Deluxe Boyle's Law Apparatus by United Scientific is a gas-law teaching apparatus that lets students measure pressure, volume and temperature of a trapped air sample on one compact unit. A screw-adjusted cylinder with mL markings sets the volume, a thermocouple feeds a built-in digital thermometer, and an absolute pressure gauge shows pressure. High school and college physics and chemistry instructors use it for Boyle's law labs and demonstrations. It measures 6" x 4.5" x 10" and needs one AA battery.
