Hi Jeff,
I don't know how much of the sample they actually need or what they are
testing for but here are somes ideas.
Certainly smaller samples would help.
What is the size of their reactor vessel? Maybe they could increase batch
sizes so they could sample less frequently.
Even if they stay with the same batch sizes, they may want to look
critically at their sampling frequency -- it may be that they can reduce
sample frequency without really affecting quality. There are some good
papers on application of Taguchi methods that examine this in painful
detail.....I'll see if I can dig one up from my files. Also, they may
be able to substitute other measurements (horsepower requirements on the
agitator, for example) as a means of monitoring reaction progress,
especially early in the batch....
Return the sample to the batch. A local paint company does that here when
they create their paint resins in a large reactor.
Could they use a container with a thin plastic liner like a paint pot liner
and recycle the liner?
Drain the jars in a chilled atmosphere. Stops or slows the resin curing process.
Interesting thought. I would've suggested just the opposite because of
the viscous nature of the fluid (heating should make it flow better).
However, the curing issue creates an interesting problem. They ought to
experiment with temperature at any rate.
