These foam plugs are designed to fit most test tubes and vials.

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

Nose cone variety pack for Estes BT-50 rocket body tubes.

Teach fundamental concepts of genetic diversity and real world applications in marine biology.

Pre-calibrated test tubes and labware give fast, accurate results in the classroom or in the lab.

This nickel-plated spoon and spatula tool is 14.9 cm long.

Study the motion and behavior of gas molecules with this intriguing demonstration. An electric motor, running at 4 to 12 V DC, vibrates a small platform inside a transparent tube. This platform then violently vibrates the many small stainless steel balls inside the tube.

Generate a uniform magnetic field perpendicular to the axis of the Teltron D series tubes.

Pre-calibrated test tubes and labware give fast, accurate results in the classroom or in the lab. 

The HOBO® water Level data logger features high accuracy at a great price and ease-of-use, with no cumbersome vent tubes or desiccants to maintain.

This unusual-looking Echinoderm, a small ball-shaped organism, displays radial symmetry. It moves via tube feet.

Check valves allow one way passage of water or air through tubing.

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.
