The item

  • www.mansfieldcryogenics.com
  • Basically, we want something along the lines of one Dewar as a one off delivery. We also need a set of gloves to handle the stuff.

update

Delivery is scheduled for the 8th of May. We are being given a set of gloves for free (which is very nice). A cage with a lock will be provided, next to the laser cutter near the window slots on the ground floor. Safety instructions will be printed and posted here, and on the mailing list in the next few days.

We didnt meet the extension pledge in time, so these who pledged for the initial one off batch are the only ones liable to pay on this pledge. If demand outstrips supply, a new extension pledge will be formed.
