[Nhcoll-l] Heatsealer

[Mariana Di Giacomo]

Hi Lennart,

I have to second Rachael's comments. Make sure you are not leaving any
holes while you are doing the taping and the specimens will be well
protected before going into the freezer. The difference between freezer and
low oxygen in this sense is that in both cases if you see the hole, it's a
problem, but microholes are a problem for low-oxygen but not an issue for
freezing, so heat sealing is not necessary.

Best,
Mariana
