Hello Everyone,

I have a question about the sample temperature range people have been able
to achieve/ use the BCU 1 chiller for.

I have a user who has not used the chiller in a few years and last worked
with the chiller prior to my time here. The user was wanting to know what
were the low end of sample temperature ranges we could realistically
achieve with the BCU 1 chiller? I know according to the manual the
recommended range is from 0 C to Room Temp. When I tried to see if I could
get the temp lower it seemed to only be able to get a sample down to around
-3 C. But the user insists that it was the BCU 1 to achieve the lower temp.
I am just looking for real-world experience from users.

We do have a Cryo Diffusion CDL 27 that is not currently in use but had
been used in the past, but the user is insistent that the BCU 1 was the
chiller used for the temps he wants to achieve?

I am just wanting to get peoples experiences on what they could
achieve with the BCU1.

Sincerely,

Silas
