[3dem] [External] Cryo claw

[Walsh, Richard]

We use these to fish out falcon tubes (and spilled grid boxes too).

Ask an astronaut, the gloves of their suits must be good enough for low temperatures

Hi all, we have one of these (attached) and I have retrieved a puck with it before. However, I got lucky and did it without looking!

Best,

Hi Reza, David,

Alternatively, you can buy very long crucible tongs (~ 20 inches or longer) and hope to get lucky. If you empty out all the cylinders from the dewar and wait for a few minutes you should be able to get a good view with a flashlight to find its location and get it out.

HTH,

Axel

Reza,

Your best bet is probably to empty the entire dewar.  Large styrofoam boxes are very good for this sort of thing...

Hi,

We've lost a 50ml falcon tube in our cryo dewar. Is anyone aware of a good claw that can retrieve it? Thanks.

Best wishes,
Reza
