Hi, Would be interested to hear your views on air-conditioning requirements for a confocal microscope rooms.

We have central airconditioning with temperature sensors in each microsocpe room but this set up does not keep the temperature sufficiently stable. We are thinking of installing a dedicated air-con unit as used in computer rooms (CRAC). This should maintain the temperature and control humidity but prices for such units are very high.

Best regards,
Anya

Hello Dr. Anya Salih,

Talk with the vendors of your confocal microscopes to get suggestions, if
you have not done so.

Hi Anya,

We found that there's a benefit to using a large room (with a large
plenum above the acoustical tiles) subdivided into sections using
blackout curtains. The large size of the airspace evens out temperature
differences. The only important thing to ensure is that the supply
registers are NOT above your confocals. This type of setup also promotes
a more social microscope experience but that may not be great for everyone.

Another option we are using is a modular cleanroom. We're using a
biobubble (see: http://www.biobubble.com/biobubble_ppt/img127.html) to
house 2 microscopy setups. Airflow and temperature are stabilized.

Cheers,
- Damir

Hi Anya

We had the same problem with our argon and 2 P lasers warming up the room (3 other microscopes) and the air con not being able to stabilize the temperature. Installing above the lasers hoods (no fan, just large metal funnels) that channel the heat to the main ventilation output worked well for us and was cheap. Additionally, you can also hang a curtain around the lasers, but  you must make sure that you have the proper ventilation/hood on the laser side of the curtain. This has the advantage that the curtain can be pushed to the side for servicing. It often requires moving the lasers lightly away from the microscope and grouping them together which is not always possible.

Med vänlig hälsning / Best regards
 
Sylvie
