RE: H&E Auto Stainer

From:dizefamily <>

Hi all,

We have had the Hacker stainer for about 10 years now. We have two of them
actually. We tend to have a backup instrument for all of our equipment if
feasible. Yes they are BIG but we have adjusted to that. We do not dilute
anything. Our time is set for 1 minute 20 seconds. When running down
specials we simply count the number of containers then set a clock for the
appropriate time then go get our slides off the stainer at that time. You
can remove slides at anytime you wish. You can change reagents on the
stainer at anytime without stopping the instrument. In that 10 years we have
had a problem only three times I think. We do use Richard Allan staining
solutions now but have not always. For several years we used only homemade
stuff (even hematoxylin)and that was fine too. We plan to replace our oldest
one in January and will get another Hacker. We have Sakura coverslippers.
Please feel free to email if you have more questions.

More info,

Sorry that I forgot to mention that Fisher is including the Hacker
coverslipper, too. I really like the coverslipper and our cytology personnel
will be able to use it for their coverslipping needs, too. All in all, it is
a good deal. I just have to think about the size of the stainer and if it is
worth giving up precious bench space for it, besides all of the technical
aspects of this stainer. I know that there are other stainers that offer
more flexibility with individual station time programming, etc. This is a
big plus especially for deparaffinization special stains, etc. I want a
stainer that is dependable, ease of operation (I have some assistance from
military med. techs), and mostly trouble free operation in the least. So, if
anyone has used this stainer, keep the comments coming. I'm "listening".

We had a Hacker Linear stainer at the lab I used to work at.  It worked very
well, but did require a lot of work to get the staining right.  I believe
station was set at 2 minutes and you just need to add or subtract the number
stations to get the desired result (e.g., 4 Hematoxylin stations at 2
each = 8 minutes total in the stain, 1/2 strength Eosin to eliminate
overstaining and very low concentrations of acid alcohol to prevent totally
de-staining the tissues).  I can get you the exact times, stations, etc., if
