If students must hand in data, choose the Superconductivity Experiment Kit ($1,550–$1,710). It measures the resistive transition of a YBCO bar near 92 K by four-point resistance, and it measures levitation force with hysteresis, which is the signature of flux pinning. Data stream over USB and plot live. If force curves alone are enough, the Force Experiment Kit ($899–$1,149) costs less. For a lecture-hall demonstration, the Maglev Kit with its Ø72 cm track is the flagship. See Which kit? for the full comparison.

The Mini Maglev Kit (from $1,497) is a portable Ø40 cm track on a wooden stand. It is light, quick to set up and in stock to ship in 5–7 days. The Outreach Program Package ($2,877) adds a DIY Kit Pro track, a handheld magnetic device and three levitators, so visitors can try it themselves. Both need liquid nitrogen, about 0.5 L per demonstration, plus a shallow tray or dewar, cryogenic gloves and eye protection.

Every superconducting kit needs liquid nitrogen, and dry ice is not cold enough. Almost every university with a physics, chemistry or biology department has it on tap. Industrial and welding suppliers often sell it for about $0.50–$2 per litre collected, and the liquid nitrogen guide explains how to source it. If cryogenics are not allowed in your space, the magnets-only kits (Magnetic Train and DIY Maglev, from $69) need nothing cooled. They teach forces, stability and levitation with permanent magnets, though they are not superconductor demonstrations. The no-LN2 maglev path explains the difference.

We can send safety data sheets for the superconducting materials and magnets, a liquid-nitrogen risk assessment template already filled in for a teaching setting, a neodymium magnet handling notice and, where your contract rules require one, an insurance certificate. Ask once in the quote form and we send them all together. The standard precautions are gloves, eye protection, ventilation and an open tray or vacuum dewar. Never use a sealed container.

Yes, and the material is free whether or not you buy a kit. For teachers has a ready-to-adapt 45-minute lesson outline with objectives, discussion questions and assessment ideas. The teacher’s guide to superconductivity has four chapters: theory, problem sets, Predict-Observe-Explain activities, and quantitative experiments and science-fair projects. It was written for high-school and undergraduate teachers and is also available as a PDF.

Yes, and it is often the sensible order. Buy one levitator or one kit first and run it past your safety officer and students. Then quote for the track or extra stations once you know it works in your setting. The range is designed to be compatible across kits. The PO and net-30 terms apply at any order value. If the money must be spent this financial year, we can invoice now and ship in the next.

Yes. Send us the link and a contact in your procurement team and we’ll work through it. Ariba, Jaggaer, Coupa, university-specific systems — we’ve done most of them.

Start this early. It’s routinely the longest step, and it runs in parallel with everything else if you begin at the same time as the quote.

The superconductor itself doesn’t degrade from use — it’s the thermal cycling and moisture exposure that eventually take a toll. Handled per the manual, a levitator in regular classroom use typically lasts several years.

Your actual recurring cost is liquid nitrogen, at roughly $1–3 per litre and half a litre or so per demonstration. See the liquid nitrogen guide.
