Earthquake Shake Table
Earthquake Shake Table
Our Price: $103.00

Earthquakes are a devastating natural phenomena. For people living in areas most affected by earthquakes, it is important to create buildings with strong structural integrity. This Earthquake Shake Table allows students to test different structures to see which ones can best withstand the shaking caused by earthquakes.

The base is 16” x 16” and has four strong springs at the corners, with adjustable mountings to hold a variety of tower bases. The two included C clamps hold the base firmly to the table. A tower model can have a base up to 12” on each side. A pair of motors are mounted underneath and have a protective cage to protect fingers while the table is in motion. The motors can be easily powered individually or together by a 1–5 V DC power supply (required but not included) and are intended to be a reliable and consistent source of vibrations. If a more energetic vibration is needed to test a design, the base can be manually shaken.

This is a shaking apparatus only. Users need to provide the building materials and power supply.

  • Investigate horizontal and vertical vibration
  • Motors provide reliable and consistent motion for demonstration
  • Broad base for a variety of building design

Precision Boyle's Law Apparatus
Precision Boyle's Law Apparatus
Our Price: $251.00

• Precise measurements of absolute pressure and volume for convincing verification of Boyle’s Law

• Dial gauge measures absolute pressure in kPa and psi

• Built-in length scales with movable markers for volume measurement

• Included bicycle pump permits easy and precise control of pressure

• Pressure-resistant gas tube has surrounding safety shield

Based on proven designs, this updated Boyle’s Law Apparatus permits a quantitative verification of Boyle’s Law to be quickly and easily performed. The results are reliable and more convincing than measurements obtained from a simple syringe-based apparatus.

The air sample is enclosed in a thick-walled glass tube of constant bore, so that the length of the air column is strictly proportional to the gas volume. Hydraulic oil seals the air sample in the tube and partially fills a reservoir, so the pressure in the reservoir equals the pressure in the air sample. The pressure is measured by an absolute pressure dial gauge with a range of 0 - 500kPa.

Pressure is applied using a supplied high pressure bicycle pump, which allows precise fine control for making a large series of measurements or for using the volume proportions method. A needle valve allows for controlled pressure release and a vent knob is provided for the tube.

NOTE: This item cannot be shipped USPS.
