Featured Equipment

Banana Plug Cord-Red (5 Pack)

These heavy, insulated patch cords are convenient, durable and inexpensive. The grips are stackable and made of soft plastic for flexible strain relief. The spring connectors rotate in the grips, reducing wear due to friction. Length of 75 cm, set of 5.

Student Power Supply

Student Power Supply, 18 VDC, 3 A

This high-quality, compact power supply provides the DC voltage and current levels necessary for most introductory student labs.



A great way to demonstrate the 3-D nature of magnetic fields.

AC/DC Electronics Laboratory

AC/DC Electronics Laboratory

Facilitates electricity experiments for AC and DC. Can be used as a stand-alone with a multimeter or with PASCO sensors and software.

Alnico Bar Magnets

Alnico Bar Magnets (2 Pack)

Comprised of alloy mix of Al, Ni, and Co, is stronger and last longer than Iron magnets.

Magnet Wire (22 Gauge)

Magnet wire used for crafting a coil used as an electromagnet.

Many lab activities can be conducted with our Wireless, PASPORT, or even ScienceWorkshop sensors and equipment. For assistance with substituting compatible instruments, contact PASCO Technical Support. We're here to help.
