Very strong N35 Super Ball Magnet with a diameter of 0.25 inch (about 6 mm). A neodymium magnet (a special type of rare-earth magnet) is a powerful magnet made of a combination of neodymium, iron, and boron — Nd2Fe14B. These magnets are very strong in comparison to their mass, but are also mechanically fragile and…

It is also available in Sterile packaging (individually wrapped) for medical and biological uses.Total Capacity: 7 ml, Graduated: 3 ml.Length: 15.5…
For handling test tubes with 12 to 40 mm outer diameter. Overall length about 220 mm. Made from rolled brass strip with a spring clip. Mounted in a polished wooden handle.
MSJA144 is a high quality, high precision, industrial grade, general purpose tally counter or hand counter used to count people for security, accounting or compliance issues. The internal counter made of hard plastic is a self supporting unit complete with its own frame. The plastic shell acts as a strong protective cage to add the…
Iron filings, high purity for science experiments, industrial applications and laboratory use. For quantities over 100 lbs, the product will be shipped in a bucket.
Iron filing, 12 ounce, in a shaker for convenience plus screw cap for safe-keeping. They are ideal for experimentation with magnetic fields. When you place these filings on any magnet, you can visualize 3D magnetic fields. This demonstration is very common in the classroom and this is your chance to further study the magnetic properties…
This modestly priced mechanical stroke counter provides a convenient 5 digit readout of up to 99999. This counter may be mounted on stamping machines, printing machines, packaging machines and any other machine with a turning wheel or moving arm. The spring attached to the mechanical arm prevents excess force on the mechanical arm of the…
