We have our reactors made by our local glass blower, which reduces
replacement time and costs. If you have access to a good glass blower, they
aren't too difficult a job. Faced, however, with a similar problem of delays
in the quartz tubing arriving we managed to get by by having the glassblower
cut a couple of reactors in half (horizontal cut) and then cleaning out the
old Cr. The reactors were then resealed and reused with no noticable
difference in results. I'm not certain that I would use this method for
anything other than an emergency as there is a worry about the physical
integrety of the join and whether it may introduce memory effects (although
we did not see the latter in our standards when we tried it). Anyway, if you
have a local glassblower who can do small jobs in a hurry, you might give
this ago.

Is anyone willing to temporarily part with a spare quartz HDevice
reactor?  We have some on order, but it will be 4-6 weeks before they
arrive.  We'd be happy to pay or replace it when ours arrive.
