Superconductivity, Demo Kit, Spare Disc Only

Used with Superconductivity Kit EM1584-01

Disc Size:  29mm d x 2.9mm thick

Lifespan:  depends on maintenance (approx. 2 years).  Humidity, moisture and water will break the disc down.  When the crystals break down they will produce a whitish haze.  Increase their life span by storing them protected in a freezer or refrigerator to keep the humidity down.

You can place them in a small oven at 150 deg C. after use just to dry them out.
