The Speed of a Bubble Set connects the mathematical concept of slope to the physical science concept of velocity.

Demonstrate the combining volume ratios of gases.

Preloaded Syringes For Your EMS, ACLS Or Nursing Training

Tube holder is made of robust plastic for holding D-series electron tubes. Stand has a wishbone, 360° rotating clamp made of heat-resistant plastic and two base holes for affixing the Teltron Helmholtz Coils. On rubber feet to prevent slipping.

Modern, More Efficient Tubes for General Lab Work.

Mounted on a wooden stand with a scale, the apparatus is comprised of a three-limbed glass tube with rubber tubing on the center.

100 feet of extra tubing for TeacherGeek projects.

Illustrate how spectral patterns can be analyzed from a combination of gases.

Easy and safe way to hold and power your tubes.

Boomwackers are brighly colored plastic tubes tuned by length to musical notes.

With the Resonance Apparatus, students investigate the effect of frequency on wavelength.

Demonstrate the power of a tornado in a bottle.

Comprises an inverted “U” tube with its ends closed by sintered discs. For use in experiments involving the measurement of cell EMF under conditions of forward, zero and reverse current flow. The bridge comprises an inverted “U” tube with its ends closed by sintered discs. This apparatus provides a more effective method of making reversible cells then the wet filter paper or agar gel methods. Dia. of arms 13mm, overall width 80mm, overall height 100mm.
