Plastic Wave Apparatus for Longitudinal and Transverse Motion Base_Octagonal delivering fuel from the lab

delivering fuel from the lab gas jet to Bunsen

this cast double burette clamp secures two burettes side by side for back-titration and comparative analytical procedures

Aluminum-handled collecting net swings lightweight through tall grass and air sweeps for classroom field trips and introductory entomology sampling work

and gas control on natural gas for high-temperature chemistry heating applications

sized for finer-gauge resistance demonstrations and small-scale heating elements where the heavier gauges would over-deliver current

Plastic Wave Apparatus for Longitudinal and Transverse Motion Base_Octagonal delivering fuel from the labPlastic bodied wave apparatus with eccentric discs that drive metal rods up and down as the handle turns, exposing the longitudinal and transverse components of wave motion mechanically.
