".2mL PCR tubes"

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

100 feet of extra tubing for TeacherGeek projects.

Study Wavelengths and Energy All With One Device

This apparatus is used to Verifying the Boyle’s law when air is decompressed and compressed. A horizontally mounted acrylic tube having a graduated scale (0- 300cm3) along one side. A gas tap closes the tube. Pressure gauge is present next to gas tap. By changing the position of rubber stopper, the effective length of the tube can be selected. The scale measures volume and pressure by means of pressure gauze. Boyle’s law is investigated by changing position of the stopper.

With the magnet is on the outside, it's easy to see the science behind these eddy tubes.

Achieve an airtight seal with any bell jar using our economy vacuum plate. The plate measures 24×24 cm, is constructed of polyeythlene and has a rubber pad. The hose connector accommodates 6.4 mm (¼") standard tubing.
