Amber Class A Burette with PTFE Stopcock, 50mL, 0.1mL Graduations, Borosilicate Glass Base Size_5 x 8" operated on a 30-on/30-off cycle

operated on a 30-on/30-off cycle to display the noble-gas emission spectrum without overheating the gas filling

offering additional kink resistance for bench setups that route gas or fluid lines through tight bends

running on 3-6V DC to illustrate both motor and generator operation

and a dual-scale manometer reading 0-4×10⁵ Pa and 0-58 PSI for measuring P-V inverse relationships

supporting larger-displacement kinematics investigations
