Look at all the automated H&E stain instruments on the market. I suggest that 
you consider those that offer the best benefit to your workload and workflow. 
Instruments that utilize the concept of co-location (related tasks linked 
together; oven fro drying, flexible stain configuration and Coverslipping) will 
assist you in developing a LEAN workflow. Consider how many times you need to 
touch the slides to complete all the tasks and how much walk away time you 
gain.  
 
I do not suggest by-passing the validated staining instrument oven. Placing 
slides in another oven creates variation and often results in short and 
extended drying times. All automated H&E stain instruments should be used 
according to manufacturer recommendation. My experience is that when shortcuts 
are used, quality suffers. The automated H&E stain instruments have great 
through put and you should adjust workflow to maximize the designated batch 
size and stain time.
 
Film coverslip lasts longer than 7 years. Sakura  film is the best and has 
testing to exceed 10 years. I have used it for 13 years and never had the film 
peel. If you use the knock off film products, they only have short term 
accelerated stability testing and probably do not have any version of their 
many changes to the emulsion that have real time stability testing to exceed 10 
years. There are reasons to use glass and reasons to use film. Both are great 
products, when you use them correctly and purchase quality products. Glass 
automated cover slip options on instruments do have more required maintenance 
than film.
 
CAP has made no statement about film cover slipping. In fact, the Hologic (was 
Cytech) Cytology Thinprep system is FDA approved with film as the cover slip 
and the stained and film cover slipped Thinprep slide is digitally scanned for 
analysis. To be CAP compliant, you must keep blocks and slides for 10 years. 
With the advancement of cancer hospital protocols and molecular testing, many 
institutions are considering retaining blocks and slides beyond 10 years. 
Keeping blocks and slides longer than regulation requires introduces a large 
risk factor for the retaining institution and pathologists.
 
Always be forward thinking when considering the purchase of a new essential 
instrument. Will it bar code read, can it be interfaced to LIS or tracking 
system, what analytics can be extract and will the instrument help or hinder a 
LEAN workflow? There are many choices that will meet your basic needs, but 
which one meets your essential needs?

 f with the tissue still attached.  I can say that I never seen this in my past 
position.  It is very dependent on Xylene only during coverslipping.  You 
cannot use a xylene substitute in the coverslip portion and expect to get good 
results.
