Fantastic videos---well done
The cannula transfer technique is beautifully demonstrated in these videos:

I would like to add that the technique of using syringes in handling pyrophorics is highly ill-advised.
I metioned this in one of my posts a few years go on this topic.
Use a double-tipped cannula and transfer under Argon or Nitrogen for the source bottle. The amount of materials transferred can be determined by the loss in weight.
I just don't want to read about another syringe-based accident.
PLEASE BE CAREFUL!

Subject: [DCHAS-L] Butyl Lithium & syringe safety
I have a question from our Chem dept about nButyl Lithium & syringes after I forwarded them the CEN blog on safer syringes. http://cenblog.org/the-safety-zone/2013/02/engineering-safer-syringes/
The lab's SOP calls for not reusing their syringes & only filling them 50%. I asked them to write in more clearly that they are to dispose in sharps container.
The questions I'm hoping any of you with similar hazards can help with:
1. Is there enough residual material in the syringe that it could be hazardous?
2. Should there be a sharps container stored in the fume hood for the exclusive use of these syringes (avoiding incompatible material that may be left in the syringe)
3. If not a sharps container, what/how does your labs dispose of these syringes?
