We used similar thermometers in my labs when I was a professor and had  

absolutely no issues.  The company that I run now sells a similar  
product and we've had no complaints or inquiries from customers:

Chemglass Life Sciences (formerly just plain "Chemglass") has a MS  
Word file on their web site that discusses how to reunite separated  
mercury and organic liquid columns in these thermometers:

My experience with these thermometers is that they work ok for aqueous  

applications, but not well at all for boiling/ melting point  
determinations for temperatures over 100 Celsius.  The liquid will  
separate in the in column if they are left horizontally in drawers -  
in fact it is recommended that they be stored at an angle to help  
prevent the liquid from separating in the column.

Our laboratory currently has approximately 100 of these thermometers  
in use.  We recertify them annually and have had a very low  
replacement rate.  They are sturdy and accurate.  As for separation, I  

am unaware of any notable issues with this.

I hope this is helpful.
