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.

Subject: [DCHAS-L] New procedure for transferring tert-butyllithium from Sure/Seal bottles


Hi all,


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


Compared to, say, the one in the ChemUCSD videos:
