Jay and Doug,<br>
The chiller used for NPS has developed a leak. They are trying to fix it, but the first attempt<br>
yesterday failed. It is a Model 030. It circulates water at ~20C+\- 0.1 c. WOuld you have an idea<br>
if someone around the lab has something similar that we could use if it cannot be fixed that<br>
we could ask?<br>
<br>
Cheers,<br>
Mark<br>
