Pledge: Liquid Nitrogen

Liquid Nitrogen and a bald chef with glasses looking evil

We are looking at purchasing some Liquid Nitrogen, preferably in time for the 12/05/2013 party

Pledge leader: Oni

Maintenance: Volunteer needed

Training / safety: Volunteer needed

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.

Budget estimation

• £130.00 plus VAT per delivery up to 50 litres for the Nitrogen - £156
• £??? Thermos flasks

Actions / Information

• http://stores.biochem.uiowa.edu/Pages/ln2msds.htm - current safety handling
• Secure a supplier for the correct gloves: http://www.boconline.co.uk/en/products-and-supply/cryogenic-equipment/cryogenic-protection/hand-protection/hand-protection.html
• At present, it is estimated that 50L of LN2 will covert to 30.5 cubic metres; around 5% of the volume of floor one.
• Check if the Dewar still has a functional vacuum
• Wheel upstairs and lock into place
• Liaise with Mansfield and get a date set
• Sort out a training session for these wanting to use it
• Place safety notices on cage

Specification

• Make tasty meats
• Make ice-cream
