Hi Jyllian,
I've looked at both, and I think Neal's comments are spot on. This procedure is fine for small volumes, and is reasonable for a teaching lab scenario where, say microscale
procedures are in place. If the lab is designed to teach applications that might occur for practicing chemists and larger volumes, learning good cannula skills might be more important.

The device will perform well for 1 mL titrations and perhaps up to 10 mL reactions, beyond that it will be difficult to use and offer no advantage over a canula.
The device will require some practice to learn to use and careful attention to proper procedure - that is to say, it will need operator training.
Finally, it has an equipment barrier to use that a lab will need to commit to overcoming.
Bottom line - I see an incremental advantage for small scale pyrophor use. For the application described - a teaching lab, it does make sense.
Thanks for bringing this to our attention.
Neal

Curious to know what people think of the tBuLi transfer procedure proposed in this paper just accepted by OPRD:
