Deluxe Boyle's Law Apparatus with Colored Oil, No Mercury

This Deluxe Boyle's Law Apparatus provides a safe, mercury-free method for demonstrating the relationship between gas pressure and volume. Colored oil is gradually pumped from a reservoir into a tube containing air, allowing students to observe volume changes on a clearly visible scale behind the tube while pressure is simultaneously measured by a Bourdon gauge. The Bourdon gauge is fitted with a transparent plastic back so students can observe its internal working parts, adding an additional layer of understanding to the demonstration. The strong glass tube is further protected by a plastic safety screen for added safety in classroom environments. The apparatus stands 31 inches tall on a base measuring 14 inches long and 9 inches wide, with non-slip stoppers underneath for stability. Colored oil is included with the apparatus.
