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
