[NHCOLL-L:5509] Re: alcohol meter suggestions?

[Couteaufin at aol.com]

Dear All,
 
The Anton Paar DMA 35 meter is certainly a 'State of the Art' instrument  
and has many other applications, I always recommend it on the fluid 
preservation  courses that I run.  It's price tag can be hefty however (c. 1300 UKP) 
and  if you need something to use in the meantime, the alcohol hydrometers 
are  still available and can occasionally be found in eBay for not much.
Has anyone ever used the Mettler 'Toledo' meter in this context?
 
With all good  wishes, Simon

Hi  Kirsten,  


The one I use is the Anton Paar DMA 35 density meter. You can measure the  
percentage of formalin through specific gravity or can change it to measure 
%  alcohol straight out.

I recommend it!


Email me if you need any more info from someone who's used it  specifically 
for fluid-preserved specimens.

Does anybody have any recommendations for alcohol  meters?  We need a 
hydrometer and when I was a graduate student we used  the old style glass bulb 
contraption to measure the specific gravity of the  fluid in our jars or 
carboys to determine the percent alcohol content, but  surely there's a much 
better digital version folks are using today?   I've seen a few online, but 
thought I'd ask for advice from folks in the  field.

Thanks,

Kirsten
