Re: Immersion Oil

Hi all,

sorry I am late in the discussion about the oil immersion but I only
have a small practical doubt....

How it could be that Cargille oil cost less than half compared with
Leica or Zeiss ones?

And so where is the starting point where the immersion oil plays a
decisive role in your experiment?
It depend on the magnification you are working with (and consequently
the NA) or it depend on what you are looking for?Is for the confocal
acquisition better to buy the "good" one?

Thanks in advance

Valeria

EBSA2009 Last days for early registration rates!

Dear friends,
a reminder... these are the last days for early regsitration rates at  
EBSA2009. An exciting program will be published on next week  
accordingly to the Pleanry and iNvited lecturers that you can find on  
the www.ebsa2009.org webpage. Genoa is always marvellous but in July  
is at the top!
All the best
Alby

Re: Immersion Oil - 37oC

Hi all,

I refer back to a thread from two years ago when 37C immersion oils were discussed.

We have been using the Cargille 37DF oil since then for live cell imaging.

However we have just been informed by the local supplier that Cargille has discontinued DF oils.

Does anyone know if there is a suitable replacement for use at 37C on a confocal.

Regards,

Adrian

Re: Immersion Oil - 37oC

*****
To join, leave or search the confocal microscopy listserv, go to:
http://lists.umn.edu/cgi-bin/wa?A0=confocalmicroscopy
*****

Also, is it the same as 'type 37'?  I use 'Type 37' myself but I hadn't
heard they were discontinuing it!

I spoke with one of the Cargille engineers a few weeks ago about this.  He said one of the ingredients they use for the type DF oil is no longer available.  They are currently reformulating the oil and hope to have it ready soon.  I asked to be put on a notification list so we can order it ASAP.

Adrian, just curious, did they give a reason for discontinuing these types of oils?

Re: Immersion Oil - 37oC

*****
To join, leave or search the confocal microscopy listserv, go to:
http://lists.umn.edu/cgi-bin/wa?A0=confocalmicroscopy
*****

When they let you know about the replacement, would you mind posting it on
the list?  I'm glad to see they're not just dropping the product but are
taking the time to reformulate it.

Thanks,

Craig

Re: Immersion Oil - 37oC

To join, leave or search the confocal microscopy listserv, go to:

The Cargille new formulation, called Type LDF, is now available for evaluation....received my sample today.  I don't believe it can be ordered yet but you can contact them for a free evaluation sample.  The one spec they mentioned to me that was different from the old Type DF is the viscosity index which is 500 vs. 330 for DF.

When they let you know about the replacement, would you mind posting it on
the list?  I'm glad to see they're not just dropping the product but are
taking the time to reformulate it.

Thanks,

Craig
