"micro tube racks"

WARNING: CHOKING HAZARD–Small Parts. Not for children under 3 yrs.

Investigate the spectral pattern of different gases.

To Accompany Your Tuning Fork!

Every classroom that wants to investigate spectroscopy needs a good-quality spectrum tube and power supply.

Guinea and feather tube apparatus with 6 induction coils connected in series.

Demonstration tool for fluid dynamics and the Bernoulli effect of water flow.

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

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.

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

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

100 feet of extra tubing for TeacherGeek projects.

Easy and safe way to hold and power your tubes.

Demonstrate the free-fall motion of objects in atmospheric pressure and vacuum conditions.

Investigate the relationship between the speed of a fluid and its pressure

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.
