After posting my message this morning by coincidence I had a call from a
lab about a comment I had put on a report of a high plasma zinc about
sample contamination. They have been using standard vacutainers for some
time without noting any problems - but this may explain why I have not seen
too many very low zincs from this source!
I have no experience of the sarstedt system.
