A contact key is used for experiments which require momentary current. The contact key is used to open or close a circuit. The key is mounted on a 3” x 4.5” x 3” black base with two binding posts. The arm of the contact key is plated metal with an insulated button.

Borosilicate Glass Petri Dish with reinforced rims

The Serological Pipettes are used to transfer liquids in a laboratory. The sterile serological pipettes are individually packaged. They have a capacity of 2ml and are graduated by 0.02ml. They are plastic and graduated in black and have a color-coded band at the top for easy identification.

A tuning fork is an acoustic resonator. When struck it produces several tones, a fundamental and a harmonic. The tone is primarily determined by the length of the tines. Longer tines vibrate more slowly and produce a lower tone. This tuning fork can play the note D at 288 Hz.

Borosilicate glass tubing has a low expansion rate and high chemical resistance, which makes it the most popular type of glass for laboratory use. Our borosilicate glass tubing has a wall thickness of 1mm to 1.2mm, and is available in various pack sizes. PRODUCT WARNINGS Our products are not toys ....

The Mechanical Wave Kit helps students explore standing wave patterns at different resonant frequencies. The Mechanical Wave Kit was designed to include everything needed to study wave patterns, including two Chladni plates. Sand is used with the Chladni plates to show the wave patterns produced by...

Thermometers are essential for taking temperatures in the lab. These thermometers have a white backing to make graduations easier to read and they are approximately 6" (150mm) long. Our thermometers are filled with alcohol instead of mercury for safety purposes and come in a protective plastic...

The closed design provides a significant level of added safety in the classroom by reducing the potential for spilling chemicals. It is possible to use a chemical solution for several days, as they are contained inside the structure, allowing use over multiple class periods. The tanks can easily be...

Great for demonstrating difficult-to-explain resonant waves such as propagation, reflection, and interference. Two cast metal supports, 15.25” tall x 9.5” depth, are extended by connector rods making a frame. A white cotton cloth backing is stretched between the frames to help make the demonstration...

A Gyroscope is a fascinating mechanical device that at time seems to defy the laws of gravity. The unique characteristic of a gyroscope is that once it is set spinning, it tends to want to remain in its original plane regardless of rotation of its housing. The tendency to resist change in direction...
